AT&T OAuth Scopes

OAuth 2.0 derived

AT&T publishes 8 OAuth 2.0 scopes via the authorizationCode and clientCredentials flows. Scopes are the fine-grained permissions an application requests at authorization time to act against the AT&T API on a user’s behalf.

Tokens are issued from https://api.att.com/oauth/v4/token.

This index is generated from the provider’s OpenAPI security definitions (and, where available, its documented scope reference) and refreshes on every APIs.io network build. Browse every provider’s scopes at scopes.apis.io.
