Health Gorilla API Developer Portal

Welcome to Health Gorilla's Developer Portal. Access API documentation for our suite of clinical data APIs.

This site contains technical documentation for Health Gorilla's APIs, guides, sample code, and workflows. Additional developer code examples, postman collections, and other great resources have been added to the GitHub healthgorilla/examples repository.

Health Gorilla provides FHIR-based APIs that enable developers to access the data they need to power their products. Our APIs are built on a robust master patient index, data enrichment engine, and cloud-based data repository, delivering matched and normalized clinical data.

If you have any feedback on the documentation, please don't hesitate to click "Suggest edits" at the top right of each page.

All API calls require a user key which is emailed to you by a member of the Health Gorilla team. To access keys, please submit your information through our contact form at
