Updating billing details of an active consultation service order (Java)
In this use case, the user updates the details of an active consultation like the patient’s billing details, or add a test report, or change the appointment slot (if the consultation has not started) etc. Sometimes the healthcare service provider also updates an active consultation order.
Code snippets
Client calls the BAP server to trigger update:
@PostMapping("/healthcare_consultation/update_billing_details")
public ResponseEntity updateBillingDetails(
@RequestHeader HttpHeaders headers,
@RequestBody ClientUpdateOrderRequest request) {
var response = bapApplicationService.updateOrder(request, headers);
return ResponseEntity.ok(response);
}
BAP server generates the protocol request body
