Authorization
The Bright Pattern SMS/MMS API uses basic authentication, OAuth 2.0, which enables secure resources to be retrieved while protecting user credentials.
Basic authentication is used where the username and password are exposed and can be changed by the contact center's system administrator in the Contact Center Administrator application.
All parameters are URL-encoded.
For more on authorization, see the Tenant Management API Specification, section Request Access Token.
