Clara Com Mx Authentication

Authentication

Clara’s API uses two-layer authentication: mTLS (mutual TLS) for the connection and OAuth 2.0 Bearer token for each request. Both must be present — a valid token without a client certificate will be rejected, and vice versa.

Clara declares 2 security scheme(s) across its OpenAPI definitions.
