Nylas IAM credentials API is one of 43 APIs that [Nylas](https://apis.io/providers/nylas/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include IAM credentials. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, API documentation, a getting-started guide, authentication docs, and rate-limit docs.

Create and manage IAM credentials of type `api_key` attached to principals. Credentials inherit the principal's policy, and creation returns the secret only once. Requests require an organization-bound IAM API key with the corresponding `iam.credentials.*` permission. See [credential creation and rotation](/docs/v3/auth/nylas-iam/manage-principals-with-api/#create-an-iam-credential).
