# Authorization

The ENSC API uses an API key as the primary means of authentication for secured endpoints. This API key is required for endpoints that handle sensitive operations (for example, the [`/approve`](/integrations/endpoints/token-approval) endpoint).

Refer to the [API Key generation guide](/getting-started/security/generating-keys) for instructions on how to generate, obtain, and securely manage your API key.

**Bearer Token Format:**
