NOTICE

As of September 30, 2025, the B2B Edition API authToken will be deprecated and replaced by the standard BigCommerce API X-Auth-Token. For information concerning this change, see B2B Authentication.

While authToken authentication is not expected to be fully sunset in the near future, it is advised to migrate to the new system as soon as possible to prevent disruption of functionality.
