Patient-authorized EHR integration
Practical, technically grounded answers for product and engineering teams choosing a FHIR platform, connecting to multiple EHRs, and building patient-authorized data access.
Choose the right health data access model, understand what one EHR API can unify, and evaluate FHIR platforms with practical, use-case-specific guidance.

Engineering field report · August 2026 · 14 min read
A transparent implementation report covering the patterns that repeated, the behaviors that did not, and the evidence boundary behind FinchNode’s current integration work.
Working implementation guide · 13 min read
A security-first walkthrough of discovery, authorization, callback validation, and token exchange for a standalone patient-facing application.
FHIR R4 tutorial · 11 min read
A practical TypeScript pattern for reading common patient resources without assuming that every FHIR server behaves identically.
Epic implementation guide · 10 min read
The production work around an Epic connection extends beyond the authorize URL: application registration, organization routing, exact callbacks, patient context, scopes, and source-specific validation all matter.
Oracle Health implementation guide · 10 min read
A developer guide to the parts of an Oracle Health connection that live outside the resource request itself.
Data architecture guide · 12 min read
Normalization should reduce application branching while retaining the evidence needed to explain, reconcile, and refresh every clinical fact.
FHIR operation guide · 9 min read
The operation can simplify record retrieval, but it does not promise every resource, identical server behavior, or a small response.
Reliability guide · 10 min read
A production integration needs a failure model that separates authentication, authorization, unsupported behavior, source outages, and incomplete synchronization.
Consent architecture guide · 9 min read
Source authorization answers whether data can be retrieved. Application consent answers whether a specific product may receive and use selected categories for a stated purpose.
TypeScript architecture guide · 11 min read
A timeline is not a giant sorted array. It is a source-aware projection over records with different clinical dates, update times, identities, and completeness.
Standards comparison · 10 min read
These standards overlap, but they solve different integration problems. The right choice begins with the workflow and access relationship—not whichever acronym is newest.
Buyer’s guide · 2026 · 12 min read
A practical comparison of leading healthcare data platforms—and a clear framework for choosing the right one for patient access, treatment workflows, payer data, or enterprise EHR integration.
Architecture guide · 9 min read
“One connection to all EHRs” is possible at the application layer—but only when the platform handles the source-specific work behind a consistent API. Here is what gets unified, what does not, and how to build it responsibly.
Implementation guide · 10 min read
The fastest path is not a shortcut around authorization. It is choosing the right access model, using one integration layer, and making consent, provenance, and updates part of the architecture from day one.
