# Usage

All authenticated requests to the Drizz Public APIs require the issued access token to be included in every API call. The token acts as the authorization credential for validating the identity of the calling system. Clients must transmit the token using the designated header to ensure secure, consistent, and authenticated communication across CI/CD pipelines and automation frameworks.

The access token must be passed in all API calls using the following header:

**x-api-key:** \<ACCESS\_TOKEN>
