    OAuth2:
      type: oauth2
      description: 'OAuth 2.0 is an authorization protocol that gives an API client limited access to user data on a web server.


        OAuth relies on authentication scenarios, that allows the resource owner (user) to share the protected content from the server, hosting the resource, without sharing their credentials. For that purpose, an OAuth 2.0 server issues access tokens that the client applications can use to access protected resources on behalf of the resource owner.


        Moneris recommends the use of OAuth 2.0 as it provides fine grained authorization levels.
