USPS Label Printing & Shipment Issues – Multi Carrier Shipping Label App for Shopify FAQs

    Troubleshoot USPS label printing problems and shipment creation issues in Shopify

Questions in this section:

Will the USPS Ground Advantage service update fix all previously stuck labels or only new ones in PluginHive?

The USPS Ground Advantage service enhancement automatically applies only to new orders. For previously stuck or failed labels, you need to manually reprocess those orders to apply the updated settings and generate shipping labels successfully.

Why were USPS rates failing for multiple box sizes in my order, and why was UPS label generation failing before integrating UPS OAuth?

The USPS rates were failing because the system encountered issues calculating shipping rates for the three different box sizes in your order. UPS rates were successfully retrieved; however, label generation was failing because the integration was using an old UPS API method lacking OAuth authentication. Without OAuth, the UPS labels could not be generated properly. Updating to the new UPS OAuth integration (using the UPS Rest API) resolves these issues by providing secure, authenticated access to UPS services, enabling accurate rate fetching and label creation for multiple boxes.

Why is my USPS business account not authenticating in the PluginHive app, and how can I properly add it?

The USPS business account must be added using WebTools API credentials, not your USPS login credentials. Follow these steps to properly add your USPS account: 1. Register your USPS account for the WebTools API on the USPS website. 2. After registration, USPS will send you an email with API credentials and activation steps. 3. Complete the activation steps as outlined in USPS’s instructions to activate your WebTools API credentials. 4. Obtain the required credentials (API username, password, etc.) after activation. 5. Use these WebTools API credentials to add your USPS account to the PluginHive app. Additionally, to generate USPS shipping labels, you must have a USPS eVS (Electronic Verification System) account. If this process is complex or not feasible, you can alternatively use a Stamps.com USPS account or USPS through EasyPost integration, both of which offer simpler setups.

Why does the shipment cancellation in PluginHive show “Cancel Shipment process completed. 0 of 1 canceled” and how can I successfully cancel a USPS label?

Stamps USPS labels, once generated through PluginHive, cannot be canceled directly via the PluginHive app API. To cancel such a shipment label, follow these steps: 1. Log in to your stamps.com account where the label was created. 2. Locate the specific shipment label using the order or tracking number in your stamps.com dashboard. 3. Use the stamps.com platform to void or cancel the label directly. 4. If you face any issues canceling the label, contact stamps.com support and provide them with the tracking number to request label voiding. PluginHive cannot override this limitation because it depends on the carrier API’s capabilities. Always manage the cancellation directly through stamps.com for USPS labels.

Why does my USPS shipping label show as VOID and SAMPLE in the PH Multicarrier shipping app, and how can I prevent this from happening?

The VOID and SAMPLE markings on your USPS shipping label occur because the “Enable for Sample Label” option was enabled under the Carrier Settings during label generation. This option causes the label to be generated as a sample, which displays these markings. To prevent this, ensure that the “Enable for Sample Label” option is disabled before generating shipping labels. For future orders, when generating a label, do not fulfill the order immediately—first generate and review the label to confirm it prints correctly without the sample markings.

Why do USPS shipping labels fail to generate in PluginHive after connecting the USPS account?

USPS shipping labels typically fail to generate if the payment method is not set up or configured correctly on your USPS account. To resolve this: 1. Log in to your USPS.com account. 2. Verify whether a valid payment method is configured for shipping label payments. 3. If not set up, add or update the payment method in your USPS account. 4. Contact USPS support if you encounter issues verifying or setting up the payment method. Proper payment configuration is mandatory for label generation in PluginHive.

Why do I get an “Authentication failed” error when setting up my USPS account for shipping through the PluginHive plugin, even though I entered the correct information?

The “Authentication failed” error occurs because USPS requires a specific type of account to generate labels via their API. To use USPS shipping integration directly in the PluginHive plugin, you need a USPS eVS account, which is a High Volume Shipping account authorized to create labels through the USPS API. If you do not have a USPS eVS account, you cannot generate labels directly with a standard USPS account. Instead, you can integrate USPS shipping through EasyPost, which acts as a middleware service to handle USPS shipments without needing an eVS account. To resolve the authentication issue: 1. Verify if you have a USPS eVS account; if not, consider applying for one if you qualify for high-volume shipping. 2. Alternatively, integrate USPS shipping via EasyPost within the plugin settings. 3. Refer to the detailed USPS integration options and setup instructions here: https://www.pluginhive.com/shopify-usps-shipping-options/ 4. If further assistance is needed, you can schedule a support call with PluginHive for guided setup lasting around 15-20 minutes.

Why can’t I print USPS labels, and what causes the label failure error in PluginHive Merchant (PHM)?

Label failure when printing USPS labels in PHM typically occurs because the billing details in your USPS account are not fully set up or verified. To resolve this: 1. Check your USPS account billing information for completeness and verification (such as bank account details). 2. If labels fail to generate, review the RequestResponse XML file provided with the label failure error and share it with USPS API Support ([email protected]) for detailed diagnostics. 3. Verify that your USPS account credentials associated with PHM have the required scopes enabled, including payments and label APIs. Missing payments scope can cause unauthorized errors during label generation. 4. Confirm that the Mail Owner IDs (MIDs) and Manifest IDs configured in PHM exactly match those assigned to your USPS account. Mismatched values can cause label generation to fail. After addressing these factors, attempt generating a label again to validate the fix.

Why are some USPS labels stuck and not generating for orders in my stores when using EasyPost USPS with the Ground Advantage service?

The issue arises because the Ground Advantage service, which you are trying to use for USPS label generation via EasyPost USPS, is currently not included in the available service list within the PluginHive automation rules. This means: 1. The automation rule cannot assign Ground Advantage, resulting in stuck label generation. 2. Manually attempting to select Ground Advantage for these orders also fails because the service is not selectable within the app interface. To resolve the issue for now, you should: – Avoid using the Ground Advantage service until it is officially supported in the automation rule and manual selection. – Select an alternative USPS service that is currently supported by EasyPost USPS in PluginHive. – Monitor the PluginHive updates or announcements for when Ground Advantage support is added. This limitation is a known issue related to the EasyPost USPS integration and the service offerings defined in the automation rules. Currently, no workaround exists within the app to force label creation using Ground Advantage.

Why am I unable to print USPS labels and receiving an “Insufficient account balance” error?

The “Insufficient account balance” error indicates that your Stamps.com account does not have enough funds to generate USPS shipping labels. To resolve this issue: 1. Log in to your Stamps.com account. 2. Check your current account balance. 3. Add funds or recharge your Stamps.com account balance as needed. 4. Once the account balance is updated, try generating the USPS shipping label again. This should resolve the error and allow you to print labels without issues.

Why am I unable to cancel a shipment label generated via USPS Stamps service in PluginHive?

Canceling shipment labels generated through the USPS Stamps service is currently not supported in PluginHive. This means you cannot directly cancel the label once it is created using Stamps. However, as an alternative, you can request to manually reset the order status back to “Processing” without canceling the existing label. This reset allows you to generate a new shipping label for the same order. To proceed with this option, you need to contact support and ask them to perform the manual reset for your specific order.

Why am I seeing the error “no valid services available” when trying to generate USPS shipping labels, and how can I resolve it?

This error can occur if your orders are not in the proper status for label generation. To resolve this: 1. Change the order status to “Processing” in your store’s dashboard. This action allows the system to recognize valid shipping services for label creation. 2. If the issue persists after changing the status, select the affected orders and use the “Prepare Shipment” option to manually initiate the label generation process. This workaround helps bypass the service availability issue linked to order status. Stay updated with PluginHive’s communications for permanent fixes.

Why am I receiving the error “a6cdc3c4428f4f2d888c43b7571112a4ea59d0ce8fa795f6514c6fff7d4dd6f5 unavailable contact support” when generating USPS shipping labels, even after getting approval from USPS to run transactions?

This error typically occurs when the USPS account registration or configuration in your shipping app is not completed properly. To resolve this: 1. Verify that your USPS account is correctly registered and configured within the shipping app (PluginHive). 2. If label generation fails with this error, contact your shipping app’s support team to check the carrier configuration. 3. The support team may need to reconfigure or re-register your USPS account in the app. 4. Once reconfigured correctly, label generation should proceed without this error. 5. After the fix, validate by generating a label for a test order. You may cancel the test label if needed. Ensuring proper USPS account setup in the app is crucial to avoid this cryptic error code and successfully generate shipping labels.

Why am I receiving an “authentication failed” message when trying to synchronize my store with USPS through the PluginHive app?

The “authentication failed” message occurs because to generate shipping labels through the USPS API, you must have a USPS eVS account, which is a High Volume Shipping account. Without this account, the integration cannot authenticate your store with USPS properly. To resolve this issue, you can use a workaround by connecting your USPS account through EasyPost, which automates your shipping process without requiring a direct USPS eVS account. The setup process for EasyPost integration is quick (approximately 15-20 minutes). Detailed setup instructions are available in the PluginHive article here: https://www.pluginhive.com/shopify-usps-shipping-options/. Additionally, if you need personalized assistance, you can schedule a support call using the provided appointment link to get step-by-step help with the setup.

Why am I receiving a 403 error with the message “The requested payment information is not authorized to access /payment-authorization” when generating USPS labels through the API?

This 403 error typically indicates that the app is not properly authorized to access the payment authorization endpoint with the provided account information. To resolve this: 1. Verify that the correct USPS account number is being used in the payment API request. An incorrect or unauthorized account number can cause this error. For example, switching from account number “1000287394” to “1000283864” may resolve the issue. 2. Complete Step 5 in the USPS “Getting Started” guide: Authorize your app to access protected information by entering your Consumer Key at https://cop.usps.com/navigator?wf=apisonboarding. This step authorizes your app to access payment accounts, permits, CRIDs, MIDs, and subscriptions, which are required for various USPS APIs. 3. Ensure the OAuth token has been generated properly using valid client credentials before making payment authorization requests. 4. Confirm that the app is correctly configured with the right product and permission scope in USPS’s API portal. Following these steps should resolve authentication and permission problems causing the 403 error.

Why am I receiving a 401 error with the message “EPS Primary Payment Method is not Active” when generating USPS labels through the API?

This error indicates that the EPS (Electronic Payment System) account linked to your USPS account does not have an active primary payment method. To resolve this issue: 1. Log in to your USPS EPS account. 2. Verify that a valid primary payment method is configured and active. 3. If no valid payment method is set or the primary method is inactive, update or add a new active payment method. 4. After updating your payment method, retry generating the labels through the API. If issues persist, contact the USPS Mail Shipping Support Center (MSSC) from your EPS account page for assistance with payment-related account issues.

Why am I getting errors when trying to generate USPS or Priority labels through PluginHive, while FedEx labels work fine?

USPS label generation errors typically occur because the USPS account is not fully onboarded with the USPS Developer Portal or the USPS Ship API. Common reasons include: – Missing enrollment in the USPS Ship outbound and returns program. – Lack of an active ACH debit or payment method attached to the account. – Incomplete API onboarding steps in the USPS Customer Onboarding Portal (COP). PluginHive support can liaise with USPS on your behalf to clarify and resolve these issues. You may need to complete USPS onboarding steps via https://cop.usps.com, ensure ACH debit is active, and confirm your USPS account information matches what is registered with USPS.

Why am I getting an error message when printing my USPS shipping label, and how can I fix it?

The USPS label printing error typically occurs because the shipping address is missing a required phone number. To resolve this: 1. Open the order details page in your PluginHive dashboard. 2. Locate the shipping address section for the relevant order. 3. Edit the shipping address to add a valid phone number. 4. Save the changes. 5. Retry printing the USPS shipping label. Ensuring the phone number is included and marked as mandatory will prevent this error in the future.

What support does PluginHive offer if I face issues or need personalized help configuring USPS integration and order fulfillment workflows?

Once enrollment is successfully completed and active, you will be able to generate USPS labels via the API. If you encounter any issues with enrollment or no active USPS Ship account is detected, recheck these steps and ensure all actions, especially ACH debit setup, are fully completed and confirmed.

What should I do while waiting for USPS to review and upgrade my API permissions needed for label generation through PluginHive?

While waiting for USPS to complete their manual review and upgrade process, you should: 1. Monitor your email and communication channels for any updates from USPS or PluginHive support. 2. Avoid attempting advanced functions like label printing until you receive confirmation that permissions have been granted. 3. Follow up politely but persistently with both USPS and PluginHive support if the wait exceeds expected time frames (noting they may have backlogs). 4. Keep necessary account information ready to respond promptly to any further USPS requests. 5. After receiving confirmation, test label generation immediately to verify the upgrade success.

What should I do if USPS mailing options are generating labels without enough postage for large items like fishing rods?

If USPS label postage covers are insufficient for large packages such as fishing rods, and labels generated through PluginHive do not cover delivery cost: 1. Temporarily disable problematic USPS mailing options within PluginHive to prevent customers from selecting them at checkout. 2. Manually create shipping labels for such orders using an external service or USPS directly to ensure correct postage. 3. Keep PluginHive support informed about this issue, providing examples of affected orders. 4. Await the PluginHive fix addressing USPS rate inaccuracies and postage calculation errors, which is currently in development. 5. Once the fix is released and deployed, re-enable USPS mailing options in PluginHive for seamless label generation with accurate postage.

What should I do if USPS labels are not generating and the carrier support says we need another API version, such as the Domestic 3.0 API?

If USPS labels are not generating and the carrier support indicates the need for a different API version like the Domestic 3.0 API, follow these steps: 1. Confirm with USPS that you need to upgrade or switch to the Domestic 3.0 API or any other updated API version. 2. Wait for USPS to approve or provide the necessary credentials or permissions for the required API version. This may involve new API keys or enabling permissions on existing credentials. 3. Once approval and credentials are received, update your PluginHive settings to integrate with the new API version accordingly. 4. Test label generation again to verify that the issue is resolved. 5. Keep communication ongoing with USPS and PluginHive support to troubleshoot further if needed. This process ensures that you comply with the latest USPS technical requirements and that your label generation functions correctly.

What should I do if USPS informs me there is an issue with my payment account affecting shipping label generation?

If USPS notifies you of a payment account issue that is preventing label generation, follow these steps to resolve it: 1. Access your EPS (Electronic Payment System) Account page within USPS to review your payment status and account details. 2. Contact the USPS Mailing & Shipping Solutions Center (MSSC) directly for assistance specific to your payment account issues. The MSSC staff can provide detailed support and help resolve any payment or authorization problems. 3. Once the payment or authorization issue is resolved by USPS, you should be able to generate shipping labels successfully again. 4. If the issue persists or you need further help, you may reach out again to your shipping app support (such as PluginHive) with updates for additional guidance or troubleshooting.

What should I do if the USPS API changes cause my USPS integration with PluginHive to fail during registration?

When USPS updates its API and causes integration failures, use the following approach: 1. Be aware that PluginHive updates its app to comply with USPS API changes, so integration may temporarily fail. 2. Reinstall the PH Multi Carrier Shipping Label app after PluginHive announces the API update release. 3. Reconnect your USPS account using your current credentials once the updated API integration is live. 4. If issues persist after reinstalling, confirm your credentials are valid and that the app version reflects the USPS API update. 5. Contact PluginHive support to confirm whether the USPS API update has been fully deployed on your app instance.

What should I do if my USPS account linked with PluginHive only has basic API access and I am unable to generate shipping labels?

If your USPS account linked with PluginHive only has basic API access, which does not allow label generation, you need to request an upgrade of your API permissions from USPS. Follow these steps: 1. Submit a request to USPS to enable the necessary API permissions for label generation. Include all required information such as your consumer key, CRID, estimated peak daily shipping volume, and the name of the third-party software (PluginHive). 2. Understand that USPS manually reviews such requests and there may be delays due to backlog. 3. Maintain communication with USPS and PluginHive support, following up to emphasize urgency. 4. Await confirmation from USPS that the permissions have been upgraded. 5. Once upgraded, attempt generating shipping labels again via PluginHive. 6. If label generation still fails, contact PluginHive support for assistance.

What should I do if label generation fails in PluginHive even after clearing postage dues on my USPS account?

If label generation continues to fail after clearing any postage dues: 1. Contact USPS support to confirm there are no remaining billing or account problems affecting label services. 2. Request USPS to verify that your account status is fully updated in their system and that there are no delays in reflecting your recent payments. 3. If possible, obtain the RequestResponse XML file from the failed label generation attempt, which can help USPS and PluginHive support diagnose the issue further. 4. If the problem persists despite USPS confirming your account is in good standing, contact PluginHive support with your order details and relevant files for additional troubleshooting assistance. This approach ensures that both USPS billing and PluginHive configurations are checked thoroughly to resolve label generation issues.

What should I do if I linked my USPS account but am unable to print shipping labels using PluginHive?

If you cannot print shipping labels after linking your USPS account with PluginHive, follow these steps: 1. Confirm that your USPS account is linked correctly in PluginHive with the correct consumer key and credentials. 2.

Test generating a USPS shipping label from the PluginHive app once approval is received. 5. If issues persist, continue working with PluginHive and USPS support to troubleshoot further.

What permissions do I need to enable in my USPS account to print shipping labels after linking it with PluginHive?

When linking your USPS account with PluginHive to print labels, the app uses the USPS APIs that require specific permissions enabled. By default, the connected app (via your consumer key) has access to these USPS API products with a quota of 60 calls per hour each: OAuth, Addresses, Service Standards, Service Standards File Download, International Pricing, Domestic Pricing, Shipping Options, and Locations. To print shipping labels (which involve APIs beyond these default permissions or higher usage), you may need additional API permissions or a quota increase. This requires providing USPS with details such as your consumer key, CRID, estimated peak daily shipping volume, and the 3rd party software used (PluginHive) so they can review and enable the necessary API access or increase quotas accordingly.

What permissions and credentials are required to successfully connect a USPS Ship (REST) account in PluginHive?

Successful USPS integration requires: – Customer Registration ID (CRID) – Account Number – Mailer Identifier (MID) – Manifest MID – Return MID (optional) – Consumer Key and Consumer Secret (API credentials from https://developer.usps.com) Additionally, your USPS account must have full permissions enabled to: – Display accurate shipping rates – Generate shipping labels Ensure the credentials are current and authorized by USPS, especially after any API updates or account changes.

What information should I provide to USPS to request additional API permissions or quota increases for shipping label printing?

To request additional API access or quota increases from USPS, provide the following details: – Your USPS consumer key (a unique app identifier). – Your CRID (Customer Registration ID), if available. – Your estimated maximum daily shipping volume during peak periods (e.g., 300-500 labels per day). – The name of the third-party software or plugin you use to access USPS APIs (e.g., PluginHive). Supplying this information allows USPS to validate your usage needs and grant appropriate API permissions or quota expansions.

What information should I provide to USPS API Support when investigating label generation errors with a 401 status code?

To facilitate effective troubleshooting by USPS API Support, provide the following information: 1. The full OAuth authorization request and response involved in the API calls. 2. The payment request and response payloads that correspond to the label generation attempts. 3. Exact timestamps when the errors occurred to correlate logs and system statuses. 4. Any XML or API request/response files related to the failed label generation attempts for detailed analysis. This detailed information helps USPS Support pinpoint authentication or payment method issues accurately.

What information do I need to provide to USPS customer service when they ask about PluginHive software for API permission upgrades?

When USPS customer service requests information about the third-party software for API upgrades, provide the following details: – The name of the software/plugin: PluginHive. – Your USPS consumer key and account information. – Estimated maximum daily shipping volume during peak periods (e.g., 300-500 labels per day). This information helps USPS validate your usage and enables them to approve the necessary API access or quota increases.

What does the error message “unavailable” mean when generating USPS shipping labels in PluginHive, and how can it be resolved?

The “unavailable” error indicates that the USPS API is denying label generation due to incomplete authorization of the PluginHive app to access protected USPS resources. To resolve this, you need to complete Step 5 in the USPS developer onboarding process called “Authorize App to Access Protected Information Resources.” This involves: 1. Visiting the USPS API onboarding page at https://developers.usps.com/getting-started 2. Entering your Consumer Key in the USPS authorization portal at https://cop.usps.com/navigator?wf=apisonboarding 3. Granting access permissions for the app to retrieve payment accounts, permits, CRIDs, MIDs, and subscriptions required for several USPS APIs. Once authorization is complete, notify PluginHive support to proceed with generating shipping labels. This step ensures the app has the required permissions to interact with USPS services and prevents the “unavailable” error from occurring.

What does the error message “Only mail classes Priority Mail and Express Mail are allowed for this account” from Stamps USPS mean, and how can I resolve it?

This error indicates that your Stamps USPS account is restricted to creating shipping labels only for Priority Mail and Express Mail services. To resolve this issue: 1. Verify that you are selecting either Priority Mail or Express Mail as the shipping service when generating labels through PluginHive. 2. If you need to use other USPS mail classes, contact the Stamps USPS support team to inquire about your account restrictions and request enabling additional mail classes. 3. Ensure that your shipping settings in PluginHive align with the allowed mail classes linked to your Stamps USPS account. 4. After confirming or updating your account permissions, try generating the shipping label again using the allowed service types. If the error persists after following these steps, provide the error details to Stamps USPS support for further assistance.

What does the error “The X-Payment-Authorization-Token token provided with the request is invalid or missing” mean when generating USPS shipping labels, and how can it be resolved?

This error is returned directly by USPS and indicates a payment-related issue at the USPS account level. It means the authorization token used in the label generation request is either invalid or missing. To resolve this: 1. Verify the USPS account credentials and payment status to ensure the account is active and in good standing. 2. Contact your USPS account representative or the USPS API Support team at [email protected] for detailed assistance related to your account payment setup. 3. Provide them with the label request logs (which your shipping app or PluginHive support can provide) to help diagnose the issue. 4. You may also share your support ticket from PluginHive support with USPS to streamline communication. If needed, keep PluginHive support in the loop by contacting [email protected] for additional help coordinating with USPS.

What does the “Insufficient OAuth scope” error mean when generating USPS labels through the API and how can it be resolved?

The “Insufficient OAuth scope” error indicates that the OAuth token used in the API request does not have the necessary permissions or scopes to access the requested USPS resource. This usually happens because the default USPS API product assigned to the consumer key only includes a limited set of API access permissions and call quotas. To resolve this issue: 1. Verify the authentication credentials (Consumer Key and CRID) to ensure they are correct and linked to the appropriate USPS account. 2. Confirm which USPS API product is currently assigned. The default “Public Access I” product includes only a basic set of APIs with a limited quota (60 calls per hour). If your application requires access to additional APIs or higher quotas, you must apply for an upgraded API product. 3. Provide USPS API Support with: – Your Consumer Key – Your CRID – An estimated maximum daily shipment volume (peak load) 4. USPS API Support will then evaluate your request and may upgrade your API access or grant higher quotas to cover your application needs. 5. After approval, update your OAuth token to include the new scopes granted with the upgraded product. Following these steps will ensure that your OAuth token authorizes the required API calls and prevents “insufficient scope” errors.

What does the “Insufficient account balance” error mean when generating a USPS shipping label, and how can I resolve it?

The “Insufficient account balance” error indicates that your USPS account linked to PluginHive does not have enough funds to process the shipment. To resolve this: 1. Check your USPS account balance to verify the available funds. 2. If the balance is low, update or add funds to your USPS account to meet the shipment requirements. 3. Contact the Stamps USPS support team for guidance on how to update the account balance, if needed. 4. After replenishing the balance, attempt to generate the shipping label again through PluginHive. This should clear the error and allow shipment creation.

What credentials are required for integrating my USPS account with the PH MultiCarrier Shipping Label app and how are shipping label payments handled?

You need to provide your own USPS REST API credentials to connect your USPS account with the app. Payments for shipping labels are handled directly by USPS through your USPS account billing. The app does not process payments; you will be charged by USPS for all shipping labels generated via the app. To start, install the app, add your USPS account credentials, and test the features during the free trial period.

What credentials and setup steps are required to successfully integrate USPS with PluginHive?

To integrate USPS, you need the following: 1. USPS Web Tools API Username and Password, which you obtain by registering at https://registration.shippingapis.com/. These credentials are different from your regular USPS login. 2. Ensure you have a USPS eVS account (for high volume shipping) as it is required to generate shipping labels through the USPS API. If you do not have an eVS account, you may alternatively use a Stamps USPS account for label generation. 3. After receiving your Web Tools API credentials, you must enable the required USPS APIs for your account. The instructions for enabling these APIs are usually provided in the email containing your Web Tools API credentials. Completing this step is essential for authentication and successful integration. 4. Detailed USPS integration options and guidance are available in this article: https://www.pluginhive.com/shopify-usps-shipping-options/. 5. If API credentials are correct but you get an ‘Authentication Failed’ error, verify that the USPS account’s APIs are activated as per the next steps mentioned when you obtained your credentials.

What causes the “Insufficient OAuth scope” error when generating USPS labels through the API and how can it be resolved?

The “Insufficient OAuth scope” error occurs because the OAuth access token lacks the necessary permissions to access the requested USPS API resource. To resolve this: 1. Verify that your USPS Ship account is fully enrolled and active, as API access requires enrollment in the USPS Ship payment platform. 2. Ensure that your application has been assigned the appropriate OAuth scopes corresponding to the USPS API features you need (e.g., label generation). 3. If you are only on the default product plan, which includes limited APIs and a quota of 60 calls per hour, you may need to request an app upgrade to gain access to additional APIs and higher quotas. 4. Confirm that you are using a valid OAuth access token generated with the correct client credentials (consumer key and consumer secret) and that this token is not expired (tokens are valid for 8 hours). 5. If your app requirements have changed, submit a request to USPS API support to review and upgrade your app’s access and quota accordingly.

What can PluginHive users do if the USPS API upgrade process is taking longer than expected?

If the USPS API upgrade process is delayed: 1. Continue polite follow-ups with USPS API Support to request status updates on your application. 2. Inform PluginHive support about any delays for their assistance in escalation. 3. Confirm you have provided all required documentation and information to USPS accurately to avoid further delays. 4. Keep track of any support threads or communication involving USPS and your account for reference. 5. Understand that manual reviews by USPS can take significant time due to backlog, but consistent follow-up may help expedite the process. 6. Once permissions are confirmed upgraded, resume label printing activities normally in PluginHive.

What are the limitations of USPS and FedEx carriers in PluginHive regarding shipping of alcohol and hazardous materials?

The key limitations to note are: – USPS (via EasyPost) does **not** support shipping of alcohol products at all, leading to label generation failure if alcohol is present. – FedEx does not support processing shipments where both Dangerous Goods (Hazmat) and Alcohol options are enabled for the same product in the shipment. Attempting to ship such a shipment will cause errors. Therefore, when using these carriers through PluginHive, carefully review product attributes: – Avoid combining alcohol and Hazmat products in one shipment. – Choose a carrier that supports your shipment profile based on the product’s special shipping requirements. – Test shipment generation on the carriers’ respective websites to verify allowed shipment types before attempting processing in PluginHive.

What are the key USPS API endpoints involved in OAuth and payment authorization for label generation?

The key endpoints are: 1. OAuth Token Endpoint: https://apis.usps.com/oauth2/v3/token – Used to generate an access token with client credentials. 2. Payment Authorization Endpoint: https://apis.usps.com/payments/v3/payment-authorization – Used to authorize payments associated with USPS account numbers and generate labels. Correct usage involves first obtaining a valid OAuth token and then using this token in the payment authorization request payload containing roles, account numbers, CRIDs, and MIDs as required.

What alternative does PluginHive offer if I face difficulties generating USPS shipping labels with my USPS account?

If you face challenges with your USPS account, PluginHive offers an alternative USPS integration via EasyPost, which is free of cost. Benefits and next steps include: 1. Connect USPS shipping via EasyPost directly through PluginHive. 2. Generate USPS shipping labels quickly within the PluginHive platform. 3. Receive assistance for setup by scheduling a call with PluginHive support. 4. Use the online appointment link provided by PluginHive to book a convenient time slot for personalized help. This alternative provides a seamless way to manage USPS shipping without direct USPS payment or configuration issues.

Is there a way to generate a consolidated USPS scan form in PluginHive that includes all the labels created in a day for easy scanning by the pickup driver?

Currently, PluginHive does not support generating a consolidated USPS scan form that combines all package barcodes into one printable form. Each package label must be scanned individually using the provided labels. The development team is aware of this demand and is actively working on adding this feature, but it is not yet available. Until the feature is released, users must continue scanning labels individually or use external carrier tools for manifest scanning.

Is the policy regarding shipping labels and charges the same for FedEx, UPS, and USPS?

Yes, the policy is consistent across FedEx, UPS, and USPS. When you generate a shipping label for an order, you will not be charged for the shipping amount unless the label is physically scanned by the respective carrier’s agent (FedEx, UPS, or USPS). This means you can generate labels without immediate charges, allowing flexibility in shipment processing.

Is EasyPost’s USPS integration service free, or does it require payment?

Creating and using an EasyPost account is free of cost. However, while EasyPost does not charge for the integration itself, you need to maintain a wallet balance within your EasyPost account to pay for the USPS shipping labels you generate through the app. In summary, the integration is free, but postage fees are paid as you generate labels.

If I want to drop off packages at the USPS branch myself, how should I handle pickups in PluginHive?

If you plan to take packages to the nearest USPS branch yourself and do not require a pickup, simply generate the shipping labels within PluginHive and mark the relevant orders as fulfilled. There is no need to request or schedule a pickup service in this case. This workflow supports manual package drop-off without configuring pickup options.

I only see options to add FedEx or USPS accounts when trying to add another carrier account in Shopify. How do I add a second UPS account?

The option to add a second UPS account does not appear in the Shopify settings because UPS accounts must be connected via the PluginHive Multi Carrier Shipping Label App, not directly through Shopify’s native shipping settings. To add a second UPS account: 1. Open the PluginHive app from your Shopify admin dashboard. 2. Go to the “Add Shipping Carrier Account” section within the PluginHive app. 3. Click “Start” and select UPS (OAuth) to link an additional UPS account. 4. Complete the authentication steps as prompted to connect your new UPS account. This process allows you to manage multiple UPS accounts independently within the PluginHive app for shipping label generation and order fulfillment.

How should I proceed if I encounter a label generation failure due to a temporary USPS API outage?

If you experience label generation errors suspected to be caused by a USPS API outage: 1. Confirm the outage status with USPS API support or system status announcements. 2. Wait until USPS confirms that the outage has been resolved. 3. Retry your label generation requests after the outage is cleared. 4. If errors persist post-outage, provide detailed request-response logs and error messages to USPS support for further investigation.

How should I manage USPS shipments in PluginHive if I intend to drop off the packages myself without scheduling USPS pickup?

If you plan to drop off USPS packages personally without arranging USPS pickup, follow these steps: 1. Generate and print shipping labels for the orders using PluginHive—either through automation or manual processes. 2. Mark the respective orders as fulfilled within your order management system after printing labels. 3. Since you are handling the drop-offs, do not request or schedule a USPS pickup via PluginHive or the USPS system, avoiding any conflicting pickup instructions. 4. Physically drop off your packaged shipments at the nearest USPS branch at your convenience. This process prevents confusion between manually dropped-off packages and scheduled USPS pickups, ensuring smooth shipping operations.

How does USPS handle API access quotas and what can be done if my shipping volume requires higher quotas?

USPS assigns API access quotas per application and product plan, typically with an initial quota such as 60 calls per hour for the default product, covering core APIs including OAuth, Address validation, Service Standards, Pricing, and Shipping Options. If your shipping volume exceeds this quota: 1. Submit a formal app upgrade request to USPS API support with details including your consumer key, CRID, estimated maximum daily shipping volume at peak, and the software or plugin being used (e.g., PluginHive). 2. USPS may review your needs and approve an increased quota aligned with your actual shipping activity. 3. Once upgraded, ensure that your access tokens and payment tokens are valid and used efficiently to avoid unnecessary regeneration. 4. If your requirements change later, you may resubmit or contact USPS support to redefine your quota and product settings. Managing API quota properly helps avoid rate limiting and ensures smooth shipping label generation and other API operations.

How does PluginHive handle shipping label generation when the phone number is missing from the shipping address for USPS orders?

PluginHive has enhanced the app to make the phone number optional when generating USPS shipping labels. Previously, label generation could fail if the phone number was not provided, but now the app will not send the phone number field if it is missing in the shipping address. This improvement ensures that shipping labels can be generated successfully for all orders, including those without a phone number.

How do I update my USPS account integration in PluginHive after USPS API changes have been released?

To update your USPS integration following USPS API changes: 1. Uninstall the existing PluginHive app from your store. 2. Reinstall the latest version of the PH Multi Carrier Shipping Label app, ensuring the USPS API update is included. 3. Reconnect your USPS account by entering your credentials again (CRID, Account Number, MIDs, Consumer Key/Secret). 4. Verify that your USPS account credentials are still valid and have the proper permissions enabled. 5. Test your integration by attempting to retrieve shipping rates and generate shipping labels. 6. If you encounter any problems, contact PluginHive support for assisted troubleshooting.

How do I resolve the error preventing USPS label generation after linking my USPS account with PluginHive?

The error arises because the USPS app linked by your consumer key is only enabled for default API products with limited usage quotas, which may not cover label printing or the required call volume. To resolve this: 1. Provide USPS with your consumer key, CRID (Customer Registration ID), estimated maximum daily shipping volume at peak, and the name of the 3rd party software/plugin you use (PluginHive). 2. USPS will review this information and adjust your API permissions or increase your usage quota to support label generation. 3. Once USPS upgrades your account permissions, you should be able to generate labels normally via PluginHive without encountering the error. 4. Contact USPS or PluginHive support if the issue persists after USPs confirms the permission update.

How do I resolve the “Insufficient balance” error when generating USPS shipping labels through the PluginHive app?

To resolve the “Insufficient balance” error for USPS shipping labels in PluginHive, follow these steps: 1. Check your Stamps USPS account balance to confirm if there are sufficient funds available. 2. If the balance is low or depleted, add funds to your Stamps USPS account to cover the cost of generating shipping labels. 3. Once the balance is updated, return to the PluginHive app and attempt to generate the shipping label again. 4. Ensure that you monitor your Stamps USPS account balance regularly to avoid label generation failures due to insufficient funds. If the error persists despite sufficient balance, contact PluginHive support for further investigation.

Generate and print the shipping labels for your orders as usual via PluginHive automation or manual process. 2. Mark the orders as fulfilled in your system after labeling. 3. Since you are handling the package drop-off personally, no pickup request or scheduling is necessary within PluginHive or USPS.

How do I fix USPS label generation issues across different store subscriptions using PluginHive?

When facing USPS label generation problems in multiple store subscriptions: 1. Check and move the affected orders in each store dashboard (e.g., equine-eye.myshopify.com) to the “Processing” status. This step enables label creation for those orders. 2. Confirm if label generation works after updating the status. 3. Repeat this process for each subscription as needed. By ensuring orders are in “Processing” status, you align with PluginHive’s current system requirements to generate USPS labels without errors.

How do I fix the error “Invalid USPSAccount credentials: Street Address is required” when creating USPS shipping labels?

How do I disable delivery confirmation for USPS shipments marked as “Limited Quantity” hazmat in PluginHive?

To comply with USPS policies for Limited Quantity hazardous materials shipments: 1. In the shipment or product’s dangerous goods configuration, specify that the shipment is “Limited Quantity.” 2. Disable the “Delivery Confirmation” option when generating USPS shipping labels. This is mandatory for USPS hazmat shipments. 3. Save the changes and generate the label.

How do I complete OAuth token generation and start using USPS APIs after enrolling in USPS Ship?

After enrolling in USPS Ship and setting up your app, to generate your OAuth token and begin using USPS APIs, proceed as follows: 1. Follow Step 6 on the USPS Developer Portal “Getting Started” guide for OAuth token generation: https://developers.usps.com/api/81 2. Use the Consumer Key (client_id) and Consumer Secret (client_secret) obtained during app registration in the COP. 3. Authenticate your application by implementing the OAuth protocol to request an access token using these credentials. 4. Once you receive your OAuth access token, use it as the authorization bearer token in your API calls. 5.

If you are unsure about any OAuth implementation details, refer to USPS API documentation or developer support for code samples and specification details.

How can the USPS Scan Form (Shipment Confirmation Acceptance Notice, PS Form 5630) be integrated into the shipping app to allow a single barcode scan for multiple packages?

Currently, the PluginHive shipping app integrates with USPS APIs to generate shipping labels and track packages but does not directly support the USPS Scan Form (PS Form 5630). This form allows USPS to accept multiple packages at once using a master barcode, streamlining shipment acceptance. However, USPS has not documented support for the Scan Form through their API, and therefore this feature is not available in the app at this time. Users seeking this functionality should confirm with USPS API support whether Scan Form capabilities are offered via API, as PluginHive can only implement features supported by USPS API endpoints.

How can I verify that my USPS app has the correct API access and permissions set up?

To verify your USPS app’s API access and permissions: 1. Confirm your app is correctly associated with the required USPS product (e.g., “Shipping Suite IV”) in the USPS API portal. 2. Check that your Consumer Key (client_id) is properly registered and active. 3. Authorize your app to access protected resources by completing Step 5 on the USPS Getting Started page at https://cop.usps.com/navigator?wf=apisonboarding, which links your Consumer Key to access payment accounts, permits, CRIDs, MIDs, and subscriptions. 4. Generate an OAuth token successfully at the endpoint https://apis.usps.com/oauth2/v3/token using your Consumer Key and Client Secret, ensuring the token contains all the necessary scopes (e.g., payments, shipments, labels). 5. Use the OAuth token in subsequent API requests to verify permissions. If all these configurations are correct, your app will have the necessary permissions to access USPS APIs.

How can I troubleshoot errors when generating USPS shipping labels in Shopify while using PH Multi?

Confirm that your USPS account is connected properly, especially since USPS has migrated to the USPS REST API for label services. 3. Ensure your USPS account is configured to use the USPS REST API credentials; this connection is necessary for label generation. 4. If label creation still fails, reach out to Shopify support to investigate any Shopify-specific errors or account issues affecting label purchasing. 5. Contact PluginHive support if you need assistance linking your USPS account to the REST API or generating labels within the PH Multi app.

How can I test USPS label generation in PluginHive Merchant without creating a false order?

Currently, the only way to confirm your USPS account setup and label generation functionality in PHM is by attempting to create a shipping label for an actual order. This means: 1. Use an existing order in your store that requires USPS shipping and try generating the label. 2. If no suitable orders exist, wait for a new order to come through and then test label generation. PHM does not support generating labels without associating them with valid orders, so creating a “false” or test order is the only alternative method if no real orders are available.

How can I automate shipping via USPS and have labels sent to my 3PL warehouses via email or FTP using the PluginHive app, without granting them backend store access?

The PluginHive app allows you to display shipping rates, generate shipping labels, and send tracking updates automatically. However, label generation requires manual interaction within the app—you must select orders and print or download labels yourself. The app does not currently support automatically sending shipping labels outside the app via email, FTP, or other means to third parties such as warehouses. For your warehouses to access labels without Shopify backend access, no dedicated portal or user interface exists at present. You might consider organizing manual label downloads and securely sharing them with your warehouses or booking a support call for detailed consultation on workflow options.

How can I authorize the PluginHive app to access my USPS account for label generation?

To authorize the PluginHive app for your USPS account, follow these steps: 1. Obtain your Consumer Key from the USPS Developer API dashboard. 2.

Enter your Consumer Key in the portal to grant PluginHive permission to access protected USPS resources linked to your account—this includes payment accounts, permits, CRIDs, MIDs, and subscriptions. 4. Complete the authorization, which is Step 5 in USPS’s developer onboarding guide (https://developers.usps.com/getting-started). 5. After successful authorization, inform PluginHive support so they can proceed with label generation attempts using the updated permissions.

How can I add my part number and product description to 4×6 shipping labels when using USPS and FedEx through PluginHive?

Review the XML Request and Response files for failed shipments lacking phone numbers. 2. Share these XML files with USPS support to verify if a phone number might be required for your specific shipment type or destination. 3.

Could a postage due on my USPS account cause label generation to fail in PluginHive, and how long does it take for USPS to update payments in their system?

Yes, a postage due on your USPS account can cause label generation to fail in PluginHive because the USPS billing settings must be clear and up-to-date for label creation to proceed. After paying the postage due, it may take some time for USPS to process and reflect the payment in their system, which can delay label generation. To address this: 1. Confirm with USPS that your account balance is clear and that all payments have been processed without outstanding dues. 2. Double-check there are no other billing or account issues with USPS that could affect label generation. 3. Once USPS confirms your account is in good standing, retry generating the label within PluginHive. In the meantime, you can manually generate labels to avoid shipping delays. Monitor the account status until the label generation issue is resolved.
