Overview
This guide explains what shipping carrier API credentials are and when you might need to retrieve your credentials for Marketplace returns.
What are shipping carrier API credentials?
When configuring your Returns settings in Seller Center, you have the option to generate customer-initiated return shipping labels using either Walmart’s default carrier service or your own carrier account. If you want to use your existing carrier account, you’ll need to enter your complete shipping carrier API credentials in Seller Center, as it includes key information needed to generate the labels.
Where can I find my credentials?
FedEx API credentials
Log in to your FedEx account and visit the FedEx developer resource center.
