API REST Migration Deadlines

UPS, FedEx, USPS, and DHL are all migrating from XML based APIs to oauth JSON "REST" (not actually restful) APIs.

Deprecation dates of legacy APIs:

• UPS - 2024/06/03 2024-08-05
• FedEx - 2024/08/31 2026-06-01
• FedEx Web Services test environment - 2026-12-31
• USPS Label APIs Webtools - 2024/07/14
• USPS Webtools - 2025/01/25 2026/01/25
• DHL - TBD

FedEx Web Services test environment#

FedEx will disable the Web Services (WS) test environment on December 31, 2026. After that date the legacy fedex carrier with test=true stops working, and there is no way to develop, test or troubleshoot against FedEx Web Services. Finish any testing that needs the WS test environment before then, and move to the fedex-rest carrier. See Switching to New UPS, FedEx, and USPS REST API.
