Comcast Authentication API (SAT) is one of 3 APIs that [Comcast](https://apis.io/providers/comcast/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication and Tokens. The published artifact set on APIs.io includes API documentation.

The Comcast Security Access Token (SAT) endpoint issues short-lived bearer tokens used to authenticate calls to Comcast partner APIs such as the Open Ingest service. Clients exchange an x-client-id and x-client-secret pair for an OAuth-style access token valid for 24 hours, which is then attached to subsequent requests in the Authorization header.
