Marketo Engage Identity API is one of 68 APIs that [Marketo](https://apis.io/providers/marketo/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Identity and Authentication. The published artifact set on APIs.io includes an OpenAPI specification, authentication docs, and API documentation.

The Marketo Engage token endpoint. A two-legged OAuth 2.0 client-credentials grant issues a bearer access token with a 3,600-second lifetime, scoped to a single LaunchPoint Custom Service and inheriting that service's API-Only user's role permissions. Support for passing the token as the access_token query parameter is removed on 2026-08-31; the Authorization header is the only supported transport thereafter.
