For any questions about specific items, please reference the associated number (if provided) when contacting Descartes Customer Support.
New Features and Enhancements
USPS service offering for non-USPS users
🟪 USPS services are now included in rate shopping for users without an active USPS account.
ShipRush has expanded its rate shopping functionality to display USPS service rates even for users who are not currently configured with a USPS account.
This enhancement allows users to:
Compare USPS rates alongside other carriers
See whether shipments could be more cost-effective with USPS
Better understand the full range of shipping options available within ShipRush
By exposing USPS rates to non-USPS users, we aim to provide greater transparency and help users make more informed shipping decisions across our complete USPS service offering.
This feature is available to all non-USPS users as part of this release.
Resolved Issues
Finale Inventory Integration – Order Completion Reliability Improvement
🟩 Improved order completion handling for the Finale Inventory integration in ShipRush.
In certain cases, an exception during shipment creation or update could prevent an order from being fully completed in Finale Inventory, leaving it in an incomplete or inconsistent state.
To resolve this, ShipRush now always creates a new shipment in Finale Inventory containing the ordered items and immediately marks it as shipped with tracking information, following Finale’s recommended integration approach. Once the shipment is successfully marked as shipped, the corresponding order is automatically set to completed.
After an order is completed in Finale Inventory, it becomes read-only and can no longer be modified, ensuring data integrity and consistent order fulfillment.
Notification
FedEx Integration – Migration to REST APIs (Action Required at a Later Date, Beginning of 2026)
Upcoming required migration of FedEx integrations to the new REST APIs.
FedEx has announced the retirement of their legacy Web Services APIs, with a mandatory shutdown date of March 31, 2026. To remain compliant, ShipRush will be migrating all FedEx integrations to the FedEx REST APIs, which also use a new OAuth-based security protocol.
This change is required by FedEx and applies to all ShipRush users shipping with FedEx.
Important: No Immediate Action Required
At this time, no action is required from users.
ShipRush will begin prompting users to migrate starting January 5.
The notification will appear directly within the ShipRush application as a UI pop-up / in-app message.
Users should only take action after receiving this in-app notification.
No manual configuration changes are expected before this message is received.
What to Expect When You Are Notified
Once you receive the in-app notification, ShipRush will provide clear guidance on how to migrate your FedEx account. The process includes:
Updating your FedEx account to use the new REST APIs
Configuring the required OAuth authentication
Validating your FedEx credentials within ShipRush
Step-by-step instructions will be available in the following documentation:
Why This Change Is Required
FedEx is officially discontinuing their legacy Web Services integration in favor of REST-based APIs that offer improved security, performance, and long-term support. As a FedEx partner, ShipRush is required to move all users to this new integration to ensure uninterrupted shipping functionality.
Final Migration Deadline:
All FedEx accounts must be migrated by March 31, 2026. Users who do not complete the migration by this date will no longer be able to create FedEx shipments in ShipRush.
If you have questions, please refer to the documentation above or contact ShipRush Support.
