-The postman queries to demonstare Common Endpoint Application routing calls to external EMPI service and AHDS FHIR Service via single endpoint are available under `FHIR-EMPI  Integration` folder in `Fhir-EMPI Collection` postman collection available in this repo. For Queries in this collection, we are using APIM URL as our base URL and auth token of FHIR service to authenticate requests.
