Get all appointments by date / Clinic / Consultant or doctor

I need to send HL7 message to get all the appointments by date, clinic and doctor.

The appointments response include appointment informaion. Schedule information, clinic information and doctor information. Please guide.

Presume you’re wanting to do a FHIR RESTful query. If you want to actually use FHIR messaging, you’ll need to get agreement with your communication partners on what the message should look like.

You can do a query on Appointment and filter by the date, location and practitioner criteria and do an _include on Appointment.practitioner and Appointment.location. I’m not sure what you mean by “schedule” information.
