The POST /{environmentId}/flows/{flowID} operation uses the {flowId} value from the /{environmentId}/as/authorize response to get the flow and the current flow state. The status property in the GET /{environmentId}/flows/{flowID} response specifies the initial flow state, which determines the possible next actions in the authentication workflow.

The HAL links in the response includes the registration.experience action as an option for this flow. This option is available because the sign-on policy has enabled the registration action and uses the flow execution to initiate the flow definition steps defined in the flow definition resource.
