Enter your credentials to Maventa testing environment, to authenticate and try things out with the Swagger UI. This will fetch a Bearer token using OAuth2 with the endpoint POST https://ax-stage.maventa.com/oauth2/token. The token is stored in your browser's session storage (cleared when you close the tab) and used in Swagger calls done from this documentation website. The token is valid for 1 hour.

Never use your production credentials here. This is only for testing the Maventa test environment in the Swagger UI.
