Fetch FHIR R4 - Full

The API enables the fetching of discrete FHIR data (version R4). Data is delivered in json format, paginated for transport.

Note that the Greenlight API adds some metadata to the FHIR json. We introduce the metadata per resource, including information about when we retrieved it. This data helps customers who retrieve these same resources many times from Greenlight, and use these Greenlight specific elements to detect duplicates and make other decisions about the resource. Within the resource itself, the json appears the way the EHR gave it to Greenlight.

R4 data is fetched for a Request based on the date Greenlight retrieved it. New and updated R4 data elements will appear as recently retrieved.

Data needed to make a FHIR Data API request are provided in the response to a Find Changes API request. They include your customerId, the patientId, the orderId, the requestId, as well as the time of retrieval. This collection of values identifies an individual set of R4 data (patient + records source) and allows validation.

See the All FHIR Data reference for more technical details, such as handling pagination and timestamp parameters.
