Authentication - Target Circle API

Authentication for the API is handled using standard Bearer token authentication within your HTTP request headers. To authorize your requests, format the header as Authorization: Bearer <your_api_key>. You can obtain your unique API key at any time by navigating to and copying it directly from your account settings page.

Because your API key grants access to protected API endpoints, it should be treated with the same care as a password. Keep it strictly confidential by avoiding hardcoded values in public code repositories or client-side applications to ensure your account remains secure.
