After an end user provides the input required by the flow, the callback endpoint returns the flow to the authorization server. This endpoint requires an authorization code query parameter for authorization_code grant use cases. It also supports optional parameters such as state and session_state query parameters in the request URL. The sample shows the GET {{authPath}}/{{envID}}/davinci/oauth2/callback?code={{code}}&state={{state}}&session_state={{sessionState}} operation.
