# FedEx API Connection Changes Effective June 1, 2026

## Effective June 1, 2026, FedEx changed the way its parcel shippers connect to its API in third-party applications.

Starting on June 1, 2026, FedEx parcel customers using a third-party app to connect to their account are required to reauthorize their API credentials using a new multi-factor authentication (MFA) process. The reauthorization is executed entirely within the third-part application. The User Guides for the Eniture Technology products impacted by this change are linked below. Use the relevant link to access the instructions for how to reauthorize your FedEx account number.
