Get Access Token

Authentication flow

Every protected endpoint requires a Bearer token. Use this endpoint first to exchange your source-key for a short-lived JWT, then pass it as Authorization: Bearer <token> on all subsequent requests. See Source Bank – radix for the full collection-level auth context.

Prerequisites

• You must have a valid source-key, provided to you through a private channel. This key is passed as a request header and is required to call this endpoint.
• The returned accessToken expires in 5 minutes (expiresIn: 300). Re-authenticate before it lapses to avoid 401 errors downstream.
