Retrieving FHIR Data

The last step on your interoperability journey is to pull the data from Zus. You're always able to use the Zus Application to view the patient's clinical data.

Alternatively if you would like to surface the data in your own solution, you can either use our FHIR API or FQS API.

The FHIR API is a flexible standard for pulling FHIR resources either individually or in batches.

The FQS (Fast Query Service) API is a graphql like API where you can define the resources and elements you wish to retrieve.


The best way to pull patient data is by UPID - this allows users to take advantage of Zus aggregating data for a patient from all sources and connecting them via the UPID.
