Challenge
Polling-based designs miss the push model
Agnotic approach
We build webhook-first ingestion around Garmin's ping/pull so data arrives promptly and efficiently.
We integrate the Garmin Health API end to end — its push-based ping/pull model for research-grade activity, HRV, pulse ox, respiration, and stress data — normalized into FHIR Observations through a HIPAA-compliant pipeline. Real integrations, not just familiarity.
Trusted by global innovators
























Garmin's differentiator is research-grade data — high-fidelity activity, heart-rate variability, pulse ox, respiration, stress, and Body Battery from devices with long battery life and strong sensor accuracy, which makes Garmin a favorite for clinical studies and serious RPM. Access is through the Garmin Health API under a partnership, using OAuth for user consent and a push (ping/pull) delivery model rather than constant polling.
That push model is the crux of a good integration. Garmin pings your webhook when new summaries are available and you pull the detail, which means your pipeline must be built around reliable webhook handling, backfill, and de-duplication rather than scheduled fetches. Turning those rich summaries into FHIR Observations — with correct coding for each metric — is what makes Garmin data usable in a clinical or research platform.
A push-driven pipeline from the Garmin Health API to a FHIR-native record for clinical and research use.

Challenge
Missed or re-delivered webhooks corrupt data
Agnotic approach
Idempotent handling, retries, and de-duplication keep the longitudinal record clean.
Challenge
New users start with empty history

Historical backfill so trends and baselines are populated from day one.
Challenge
Partnership access delays the project
Agnotic approach
We start Garmin Health onboarding early and run engineering against sandbox access in parallel.
The exact Garmin Health API surface your integration rides on.
Summary endpoints for daily activity, epochs, sleep, HRV, pulse ox, respiration, and stress.
Webhook pings on new data plus detail pulls — built for reliability instead of constant polling.
OAuth user consent under a Garmin Health partnership with scoped access to summary types.
High-fidelity HRV, pulse ox, respiration, and stress data suited to studies and serious RPM.
Each summary metric mapped to FHIR R4 with LOINC codes, UCUM units, and device provenance.
Historical backfill and de-duplication so gaps and overlaps don't corrupt the longitudinal record.
Where it runs
Research-grade HRV and activity for study endpoints.
Pulse ox, respiration, and stress feeding an RPM dashboard.
HRV and Body Battery trends for recovery programs.
Fatigue and stress signals for high-demand workforces.
Training load and recovery for athlete health.
Activity and respiration tied to care-plan goals.

Phased rollout with webhook-health and de-duplication monitoring once live.
Delivery model
Garmin's push model shapes the whole integration.
| Surface | Method | Typical use | Notes |
|---|---|---|---|
| New-data notice | Webhook ping | Trigger detail pull | Signature-validated; retry on failure. |
| Summaries | Detail pull | Activity, HRV, sleep | Pull after ping; avoid unnecessary polling. |
| Backfill | Historical pull | New-user onboarding | Fill history so trends start populated. |
| Consent | OAuth | Per-user access | Scoped to the summary types you requested. |
Garmin Health API access requires an approved partnership; new builds are webhook-first, not poll-first.
Related proof of compliant, integration-heavy delivery: the privacy-first data layer we built for Lera Health is the same foundation we bring to ingesting research-grade Garmin data into a compliant FHIR record.

We ship Garmin integrations built for the push model and research-grade fidelity.
HIPAA, OAuth consent, and partnership requirements designed in from sprint one.
We understand research-grade endpoints and their FHIR mapping — no ramp-up on your budget.
Partnership onboarding, webhook build, and FHIR mapping run in parallel.
