A legacy cutoff already passed, and a new EU requirement is coming
UPS's older SOAP-based API reached full end-of-life in August 2024, a harder cutoff than some carriers' softer 'maintenance-only' transitions, forcing a genuine migration to OAuth 2.0 Client Credentials authentication through the current UPS Developer Portal. Any integration still assuming SOAP access simply doesn't work anymore.
There's also a real deadline ahead worth building for now: from 1 November 2026, the EU requires Product Identifier (PID) information for certain B2C shipments entering the bloc. If your freight operations touch e-commerce shipments headed into the EU, this isn't optional documentation, it's a new required data field. Separately, if your operations include LTL freight through TForce Freight, worth knowing that UPS moved Pickup, Shipping, Rating, and Tracking for TForce entirely off the main UPS Developer Portal in May 2024, that's now its own, distinct integration at developer.tforcefreight.com.
