DentaQuest FHIR Patient Access API is one of 3 APIs that [Sun Life](https://apis.io/providers/sun-life/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include FHIR, Patient Access, SMART on FHIR, Dental, and CMS Mandate. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and authentication docs.

FHIR R4 (4.0.1) read-only Patient Access API from DentaQuest, the Sun Life U.S. dental company, published under the CMS Interoperability and Patient Access Final Rule (CMS-9115-F). Third-party applications authorize a member with SMART App Launch 1.0.0 (authorization code + PKCE S256, scopes patient/*.read, launch/patient, offline_access, openid, fhirUser) against an Okta CIAM authorization server, then read that member's Patient, Coverage, Organization, Practitioner and RelatedPerson resources, including _history and version reads. Conforms to HL7 US Core (3.1.1, 6.1.0 and 7.0.0-ballot instantiated in the CapabilityStatement). Errors return a FHIR OperationOutcome. The same API is served for the Delta Dental of Massachusetts brand.
