# Health Data API Sandbox: Test Mode with Sample Patients

Flexpa Test Mode lets developers test Consent and FHIR response handling with sample data instead of real patient records. The interactive demo uses sandbox payer, EHR, and TEFCA sources. Test Mode does not predict live data completeness, latency, or reliability.

How it works: Test mode keys -> Consent session -> Sample FHIR responses. Test Mode does not predict live data completeness or endpoint performance.

## Get started

### Steps

1. Complete the interactive demo, including the follow-up questions.
2. Read the quickstart and the FHIR API reference.
3. Use test mode API keys for a Flexpa Consent session and inspect the sample FHIR responses.

## Questions

**Is there a sandbox for health records APIs?** Yes. Flexpa Test Mode supports payer, EHR, and TEFCA test sources. Use test mode API keys for the Consent flow. Test responses help validate integration code, but do not predict live data completeness or endpoint performance.
