Connecting to FedEx’s SOAP (legacy) API consists of the following steps:

Obtain a Your API Authentication Credentials


For 2024, FedEx released a new RESTful version of its API that replaces its SOAP version. Customers are asked to transition to the new RESTful API by August, 2024. If you’ve opted for these instructions, then you believe you still have access to FedEx’s SOAP (legacy) API. If so, you are welcome to follow these instructions to connect the app to your FedEx account.

To successfully connect the app, first need your API authentication credentials. If you don’t have them, sign into the carrier’s website using your username and password and then use the following link to access the Web Services page located in the Developer Resource Center.

If you prefer to navigate to the carrier’s Web Services page instead of using the Web Services link, the link to the Developer Resource Center can be found in the footer of the carrier’s home page. Once you’re on the Developer Recourse Center page, look for and then click on the link for Web Services that is present under the Other products section in the left side bar menu.

On the Web Services page, locate and then click on the MOVE TO PRODUCTION link.
