Why can I not purchase a label with Fedex through Coreware?

This typically happens when the FedEx meter number you are using has not been certified for us over their API. These steps need to be performed on your EasyPost account. Coreware makes API calls to FedEx in order to retrieve production FedEx labels and FedEx requires you to go through a certification process. You’ll want to follow these steps to obtain your API credentials. If you already have your Test credentials in EasyPost you can move to step 6:


  1. Log in to your FedEx Account and head over to their "Developer Resource Center".
  2. Click "FedEx Web Services".
  3. For test credentials, click “Develop and Test”.
  4. For production credentials, click “Move to Production”.
  5. Once you’ve completed these processes, your full credentials will be provided via a page that FedEx brings you to, as well as an email that FedEx sends you automatically. You’ll need the information from both of these sources in order to accurately fill out the entire set of credentials.
  6. After you’ve put all that information into EasyPost, you’ll need to create a Test shipment using your EasyPost Test API Key, buy the shipment, and download the label.
  7. Contact FedEx here and let them know you need help getting your account certified. Make sure to include that label you downloaded.
