Authentication

All endpoints described in this document require API key authentication.

API access is enabled per company on request — ask your Sitemark contact, or see API access in the help center. Once it is enabled, a user who can manage users creates the key in the Sitemark web app under Settings > Integrations > API.

Include your API key in the Authorization header using the ApiKey scheme:

Authorization: ApiKey <your-api-key>

If the API key is missing or invalid, you will receive a 401 Unauthorized error.
