To access the Fixture API you will need to use a username, password and api key supplied by Betgenius. Please contact your integration manager for further details.
Steps for calling APIs:
Call the Auth API to sign in using the username and password:
https://api.geniussports.com/Auth-v1/PROD/login
Take the "IdToken" returned by the auth call and add it as the "Authorization" header in the api call you are going to make to FixturesAPI
Add your API key as the "x-api-key" header in the call to FixturesAPI also
Call FixturesAPI
Note: IdTokens last for 1 hour, after which you need to sign back in or call the refresh endpoint using the "RefreshToken" from the first Auth API call
