  2. Register a client application and get the credentials (i.e the app_id and app_secret) associated to it
  3. Encode your credentials using Base64 (Basic base64({app_id}:{app_secret})) to generate the Authorization header
  4. Request an access token using your credentials, the customers scope and the Authorization header

    • access_token is to be used for endpoints' calls
    • expires_in allows you to know token's duration validity
