Authentication in Callaba Engine is token-based. In practice, the dashboard gives you a ready-to-use JWT token for API requests, so most users do not need a separate sign-in flow before calling the API.
Open General settings in your Callaba dashboard and look for the API Token field inside the account settings block. That JWT token can be copied directly and sent in the x-access-token header of your API requests.
x-access-token header.This is the most practical starting point when you need to test requests from cURL, Postman, or an internal integration script.
Include the JWT token in the x-access-token header:
x-access-token: <your_api_token>
Once you have the token, the easiest next step is usually to move into a concrete workflow such as creating an SRT server, configuring RTMP ingest, or building a player-facing delivery path.
