FedEx Last Mile Webhook Migration: Known Issues and Status Update

Dear Valued Customer, Following the recent FedEx-mandated migration to webhook-based event delivery, project44 has identified several issues affecting a subset of Last Mile shipments. We are proactively sharing this to ensure full visibility into what we are tracking and where things stand. Action Required No action is required from customers at this time. Known Issues- • Missing Tracking Events — Some shipments are not receiving events after being subscribed to the webhook, causing them to appear stuck in a Scheduled or In Transit status. • Missing Event Location and/or UTC Offset — On some shipments, events are being received without location and/or UTC offset data. This is most commonly seen on the Delivered event and can impact delivery timestamp accuracy and downstream reporting or workflows that rely on this information. • Status Mapping Corrections — The webhook is introducing new exception codes that are not yet mapped in our system, causing some shipment exceptions to surface as standard In Transit events rather than being flagged correctly. • EDD Updating After Delivered Status — In a small number of cases, Estimated Delivery Dates (EDD) are updating after a Delivered event has already been received. project44 is actively working with FedEx technical support and our internal engineering team to investigate and resolve each of these items. We will provide updates as there are meaningful developments to share. We appreciate your understanding and patience during this period. At project44, we remain committed to delivering reliable, high-availability services to our customers. If you have any questions or concerns, please feel free to contact us at support@project44.com Best regards, Customer Support Team project44
