One of the key principles of REST is that its stateless. In the Google example above, Google sends an access token to the app after the user logs in and provides consent for the app to read or write to their Google Calendar. Tokens can be managed through the NetSuite API from RESTlets to add, update and remove access as necessary; Tokens are also SSO and 2FA compatible; The NLAuth scheme is a simple, quick authorization practice that can be setup and used easily but the advantages of token authentication greatly outweigh the additional upfront configuration. The payload is where the actual information that we want to send is stored. We need to set headers on this new file so that it will only accept JSON data from a specific URL.
