We have a patient online service and have just upgraded to an interoperable FHIR back end data store. We wanted to see if a 3rd party app could connect to the back end.
Very challenging as we were learning FHIR as we were going along, as well as having to create new services in our Azure instance and that was new too. We got it working. Next time we’ll bring API documentation so others can play with it to 100% prove it (rather than us proving it)
