Security Checklist for Healthcare API Integrations

Keep credentials, PHI, logs, and third-party data flows bounded.

Classify incoming data

Classify incoming data is the first design decision for healthcare API security. Keep credentials, PHI, logs, and third-party data flows bounded. Write the boundary down before choosing endpoints or drawing clinical-looking UI so reviewers can test the actual promise.

Keep secrets server-side

For healthcare API security, keep secrets server-side should remain observable rather than becoming hidden adapter behavior. Give resolution, lookup, and interpretation separate states, then decide which failures a user may retry.

Redact logs and analytics

Redact logs and analytics needs an operational test, not only a happy-path example. Add a bounded timeout, stable error handling, request IDs, privacy-safe logging, and a fixture that proves the healthcare API security workflow fails closed.
