# Authorization

Obtain and manage access tokens via **OAuth 2.0 Client Credentials**.
Send `grant_type=client_credentials` with your `client_id` and `client_secret`.
Use the returned `access_token` in `Authorization: Bearer <token>`.
Tokens are short-lived—reuse during validity and renew on expiry.
