+Use Swagger OAuth2 Authentication
+---------------------------------
+
+Swagger can automatically redirect to OAuth2 URLs and retrieve a token for use as an Authentication Header. See the `Swagger OAuth2 Docs`_ for more information. Your redirect to supply to your OAuth provider will be ``{HOST}://{OPENAPI_URL_PREFIX}/{OPENAPI_SWAGGER_UI_PATH}/oauth2-redirect``. The code below is an example of what should be supplied as config to app in order to activate this feature.

+.. code-block:: python
+
+  app.config['API_SPEC_OPTIONS'] = {'components': 
+    {
+      'securitySchemes': {
