To complete the progressive profiling action, the flow service calls the POST /{environmentId}/flows/{flowId} endpoint operation and uses the application/vnd.pingidentity.user.update+json custom media type in the Content-type HTTP request header to identify the action.

The progressive profiling action asks for a value for the mobilePhone user schema property in the request body. If provided, the user.update action adds the user’s mobile phone number to the user record.
