View Account Info
To deploy U-Self Serve with Twilio, Account Info, including Account SID, Auth Token, API key and Token, is sent as parameters for authentication.
Account SID and Auth Token act as User name and Password, and passed as parameters in Create of Update Connector Properties at Organization level API.
Instead of Auth Token, you can create API key (SID) and Token (Secret) and use the same in the API request. The API key, Token and Account SID should be sent to the API for authentication. API key and Token helps customers to restrict access to their data. For more information, refer to Create API Key.
