Configuring a third-party OAuth provider

Enter the secure endpoints to provide OAuth authentication from a third party.

About this task

One of the following roles is required to configure OAuth Providers:

• Organization Administrator
• Owner
• Custom role with the Settings > Manage permissions

1. In the API Manager, click Resources.
2. Select OAuth Providers > Add > Third party OAuth Provider.
   1. Complete the following parameters for the first screen and click Next.

      Field	Description
      Title	Enter a descriptive title for the gateway service. This title will be displayed on the screen.
      Name	This field is auto-populated by the system and used as the internal field name.
      Supported grant types	Select from the following options: Implicit: An access token is returned immediately without an extra authorization code exchange step. Application: Application to application. Corresponds to the OAuth grant type Client Credentials. Does not require User Security. Access code: An authorization code is extracted from a URL and exchanged for an access code. Corresponds to the OAuth grant type Authorization Code. Resource owner - Password: The user's username and password are exchanged directly for an access token, so can only be used by first-party clients. Resource owner - JWT: a JSON Web Token (JWT) Bearer Token is used as a means for requesting an OAuth 2.0 access token, and for client authentication, as defined by the JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants.
      Gateway type	Select the gateway type, either DataPower® Gateway (v5 compatible) or DataPower API Gateway. For information about types of gateways, see API Connect gateway types. OAuth Providers apply to one gateway type.

   2. Specify configuration settings for the endpoints.

      Field	Description
      Authorization URL	An authorization URL where the resource owner grants authorization to the client application to access a protected resource. Example: https://example.com/oauth2/authorize
      Token URL	A token request URL where the client application exchanges an authorization grant for an access token. Example: https://example.com/oauth2/token
      Introspect URL	The introspection URL is where the API gateway validates the access tokens that are issued by the third party provider. Example: https://example.com/oauth2/introspect For more information on integrating third party OAuth providers for introspection, see OAuth introspection for third-party OAuth providers.
      Introspect cache type	The cache type determines how long responses from the third party provider are cached, if at all. Select one of the following options: No cache (default): Responses are not cached. Protocol: Defined by the cache-control header in the provider response. Time to live: Defined by the provider.
      Cache Time to Live	The length of time, in seconds, for which provider responses are cached, if the Introspect cache type is set to Time to live. The default value is 900.
      TLS Profile (optional)	Select an optional TLS profile for communicating with the third party provider.
      Security	Default is Basic Authentication.
      Basic authentication request header name	The x-introspect-basic-authorization-header is available to provide a user-configured HTTP Basic authorization header.
      Basic authentication username (optional)	The default user name for HTTP Basic authentication.
      Basic authentication password (optional)	The default password for HTTP Basic authentication.
      Token validation	Specifies the method used to determine the success of the introspection request that is sent to the third party service to validate the provided token. Select one of the following options: Connected: The query is successful if the status return code is 200. Active (default): The query is successful if the status return code is 200 and the response JSON body includes the property active: true.
      Custom header pattern (optional)	A regular expression for request headers that are to be passed to the third-party provider; for example, x-Introspect-*.
      Authorization header pass through	Select this check box if you want to retain the Authorization header for a bearer token. The default behavior is to remove this header.

   3. Enter the scopes in the third screen. A scope becomes an option in the request and response for an access token. Click Add to add additional fields for scopes. Click Next when done.

      Field	Description
      sample_scope_1	Scope for token
      sample_scope_2	Scope for token
      additional scopes	Scope for token

   4. Review the settings on the Summary panel.
