4b Payer Appointments Route

The route receives a POST request with a slot ID and a patient ID to create a new appointment on the Payer's FHIR Server. The corresponding route component checks to see if the incoming request contains all of the mandatory parameters, and then the route creates and submits a FHIR resource of Appointment type to the Payer's FHIR server. The appointment resource contains the practitioner ID, the slot ID, and the patient ID that you extracted in the previous steps. If the appointment is created successfully, the route returns a good response message.
