Sequoia Project Healthcare Directory Implementation Guide
1.0.7 - Release 1 United States of America flag

Primary API - CRUD Operations

The current version of the Sequoia Implementation Guide and all guides derived from it use the standard REST API defined in the FHIR R4 specification, found here:

RESTful API

There are some key differences between the FHIR R4 REST API and the previous Sequoia directory API, specifically with regard to the delete operation, which used to just change the active flag to false. The Sequoia directories now use FHIR versioning, which leaves the active flag alone, but marks the latest version of a resource as deleted, and subsequent reads will return an HTTP code of 410 GONE. Previously deleted entries may be discovered through the use of the FHIR history interaction.

The legacy API for pre-FHIR R4 directories can be found here
