Configuring Allowed Carriers

Once your API key is saved, Corso loads the carrier accounts connected to your shipping provider. You can control which carriers appear when generating return labels in two separate places.

• Customer Portal Allowed Carriers — Carriers available when a customer generates a return label through the Customer Portal.
• Merchant Admin Allowed Carriers — Carriers available when your team generates a return label from the Merchant Admin.

Select the carriers you want to allow in each field. Leaving a field empty makes all connected carriers available in that context.

If you add a new carrier account to your shipping provider after the initial setup, click Refresh Carriers to pull in the latest accounts. Both the EasyPost and Vesyl configuration forms include this button.
