Marketo Engage Identity API

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.

Marketo Engage Identity API is one of 68 APIs that Marketo publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Where this information came from

This is an independent, third-party profile of Marketo Engage Identity API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
