The Fast-Weigh REST & GraphQL API services use token-based authentication with a custom x-api-key HTTP header record. The token should be included with every call.

Basic Authentication has been deprecated.

We have transitioned from using Basic Authentication with username/password credentials to token-based authentication. Existing integrations will continue to work, but please note that Basic Authentication has been deprecated.
