What is the token_auth and where can I find this token to use in the API calls? - Analytics Platform - Matomo
The token_auth acts as your password and is used to authenticate in API requests. The token_auth is secret and should be handled very carefully: do not share it with anyone. Each Matomo user has a different token_auth.
