Fasten Connect API

Fasten Connect is the commercial REST + FHIR API for retrieving patient clinical records from 50,000+ U.S. healthcare systems. The API surface is documented in OpenAPI 1.0.11 at api.connect.fastenhealth.com/v1 and uses HTTP Basic authentication with public/private key pairs prefixed public_test_/private_test_ or public_live_/private_live_. Capabilities include catalog discovery (search brands, fetch organization metadata, brand logos, bulk catalog export), patient-to-provider connection orchestration via the /bridge/connect and /bridge/reconnect endpoints, organization-connection status checks, bulk EHI (Electronic Health Information) export requests with task polling and signed downloads, TEFCA synthetic-patient revocation for testing, and a support-ticket endpoint.

Fasten Connect API is one of 11 APIs that Fasten Health publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include FHIR, Healthcare Connectivity, EHI Export, TEFCA, and REST. The published artifact set on APIs.io includes API documentation, an OpenAPI specification, an API reference, authentication docs, and a getting-started guide.

Requests are made against the base URL https://api.connect.fastenhealth.com/v1.

Where this information came from

This is an independent, third-party profile of Fasten Connect API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
