USPS from ShipStation Troubleshooting Tips

Here are some common issues, potential causes, and troubleshooting tips.

Issue

How to troubleshoot or resolve

When I try to void a label, I receive the error message 'Authentication Failed'.

If you void a label and receive this error message, it could be that you have updated your Stamps.com password but haven't updated the password in ShipStation.

To fix this error, go to Settings >> Shipping >> Carriers & Fulfillment and 'Edit' your Stamps.com account. You can 'reauthorize' using your updated password and confirm when you are done.

First Class Mail International (FCMI) shipments' tracking numbers not sent to marketplaces or customers.

What it means: The tracking number provided for FCMI shipments is not always fully trackable and will often not provide any additional tracking details beyond the shipment leaving the country. Since these tracking numbers do not always provide full delivery information, ShipStation considers them to be "non-trackable" and will not include them in notifications by default.

What to do: If you want ShipStation to include FCMI tracking numbers in notifications, go to Settings > Shipping > International Settings and enable the option Send non-trackable Tracking Number to Marketplaces at the bottom of the page.

Despite the wording of the setting, it applies to both marketplace and customer notifications.
