Prerequisites
- A WWEX API Client ID and Client Secret, from Worldwide Express.
- The UPS.com account number used for billing.
- A distribution center with a complete address. Rate and label calls fail without one.
Setting up WWEX takes two steps: save the carrier settings, then add WWEX shipping methods. Checkout returns no WWEX rates until both are done.
Configuring Account Credentials
Navigate to Configuration > Checkout > Shipping, then select Carriers > Worldwide Express.

Fields appear on the screen in the order below.

Required to generate both rates and labels

Click Save.
Currently domestic shipping labels only are supported for label printing. For international labels, log into your WWEX account.
Make sure your distribution centers contain all address fields, or labels will fail.
Add WWEX shipping methods
Checkout only quotes carriers that have shipping methods. After you save the carrier settings:
- Go to Configuration > Checkout > Shipping > Methods and click New Method.
- In option 1, All shipping methods for, select WWEX and click Continue.
- UltraCart adds every WWEX service to the methods list, already enabled: WWEX: LTL (freight), the UPS domestic services, and UPS Canada Standard plus three UPS Worldwide international services. Disable or delete the ones you don't want to offer.
Because UltraCart prints domestic WWEX labels only, consider disabling the Canada and Worldwide services unless you are ready to create those labels in your WWEX account.
See Shipping Methods for the full Add Method screen.
If the store already has UPS methods from another source, for example ShipStation or the native UPS carrier, disable those once WWEX is working so customers do not see two sets of UPS options.
Troubleshooting
No WWEX rates at checkout
Check that:
- WWEX shipping methods exist and are enabled. See Add WWEX shipping methods.
- Every field in the "Required to generate both rates and labels" section is filled in with real values.
- Test Mode is set the way you intend.
- Your distribution center has a complete address.
If items have a maximum number of days in transit, use View Packing Solution on a test order to confirm WWEX methods return a delivery estimate. Methods without one are dropped for those items.
