Defining OAuth2 security scheme components

An OAuth2 security scheme component defines the settings for controlling access to the API operations through the OAuth authorization standard.

1. Open the API for editing, as described in Editing an OpenAPI 3.0 API definition.
2. Expand Components then, if there are already one or more security scheme components defined, expand Security Schemes.
3. To create an OAuth2 security scheme component, click the add icon alongside Security Schemes. To edit an existing OAuth2 security scheme component, click the component name in the navigation pane.
4. If you are creating a new OAuth2 security scheme component, you can either create it from scratch or you can reference another OAuth2 security scheme component.
   To create an OAuth2 security scheme component from scratch, provide the following information on the Definition tab:

   • Security Scheme Name: A key that enables this OAuth2 security scheme component to be referenced from elsewhere in the API definition; the reference has the following format:

     #/components/securitySchemes/Security_Scheme_Name

   • Security Definition Type: Select oauth2.
   • Flow: Select one or more of the following options:
     • Implicit
     • Resource Owner - Password
     • Application
     • Access Code
     Note: The flow options that are available for selection depend on which options are supported by the selected OAuth provider.

     If you selected Resource owner - JWT as the supported grant type when you created the OAuth provider, you must select Resource owner - Password as the Flow for this security scheme.

   • OAuth Provider: The name of the OAuth provider to be used. This is the value of the name field that was auto-generated when the OAuth provider was created.
   • Description: An optional description of the OAuth2 security scheme. You can use CommonMark syntax for rich text representation.

   To reference another OAuth2 security scheme component, provide the following information on the Reference tab:

   • Security Scheme Name: A key that enables this OAuth2 security scheme component to be referenced from elsewhere in the API definition; the reference has the following format:

     #/components/securitySchemes/Security_Scheme_Name

   • Reference from: Select a reference to another OAuth2 security scheme component.
5. If you are editing an existing OAuth2 security scheme component, provide the following information:
   • The URL endpoints (the applicable endpoints depend on the flow type):
     • Authorization URL
     • Refresh URL
     • Token URL
     Note: The URL endpoint values supplied here are maintained only for informative purposes, no validation or other action is applied to them by API Connect. The OAuth security that is applied depends on the specified OAuth provider.
   • Scopes:
     • To add a new scope, click Add. To edit an existing scope, click the options icon alongside the required scope, then click Edit.
     • Provide the following information:
       • Scope: The scope identifier.
       • Description: An optional description of the scope. You can use CommonMark syntax for rich text representation.
6. If you are creating a new OAuth2 security scheme component, click Create.
   The security scheme component details are displayed for further editing.
7. Click Save when done.
