Hi All, The existing shipping integrations for UPS, USPS, FedEx, and DHL all use deprecated SOAP/XML APIs, even though these carriers have already moved to modern REST APIs.
- UPS has officially deprecated the legacy access key and legacy SOAP/XML API in favour of RESTful API OAuth 2.0 security protocols. ( https://developer.ups.com/oauth-developer-guide) - FedEx is completely retiring FedEx Web Services (SOAP/XML APIs) by June 1, 2026. ( https://developer.fedex.com/wirc/browser/#/en-us/guides/migrate) - USPS retired the Web Tools API on January 25, 2026. ( https://www.usps.com/business/web-tools-apis/) - DHL integration uses the legacy DHL ShipIT XML API which is obsolete and has been superseded by the modern DHL Express REST API. I propose removing and cleaning up these shipping integrations because they are built on unsupported legacy APIs and are no longer maintained. Regards, Mridul Pathak
