To verify the new user account, the flow execution service calls the POST /{environmentId}/flowExecutions/{flowExId} endpoint operation and uses the application/vnd.pingidentity.user.verify+json custom media type in the Content-type HTTP request header to identify the action.

A registration flow that requires a verification action sends a verification code to the new user’s email address. As a result of submitting the form, a verification code is sent to th user, and that code is required in the request body as the verificationCode property value.
