Does anyone know how to retrieve a list of available appointment (booking) slots from OpenEMR through its API? I am looking for ways to support the (FHIR) $prefetch, $find and $book operation as defined in the Argonaut FHIR Implementation Guide (https://fhir.org/guides/argonaut/scheduling/operations.html).
OpenEMRs FHIR API does support the Appointment resource but only in a read-only mode for a specific patient.
The proprietary OpenEMR API does offer an appointment “search” capability (Swagger UI) but seems to retrieve only already booked appointments.
Anyone with a clue?
