Connect mints the PKCE pair, stashes the verifier on the OAuth-state row, and
sends the S256 challenge to the authorize endpoint. Callback reads the verifier
back and presents it on the token exchange, refusing cleanly when it is absent.
The connection-test probe hits the classic /1/user/-/profile.json endpoint.
Give the Google Health (Fitbit & Pixel) integration the same settings-card
parity WHOOP and Withings already have. It is a BYO-key provider — the user
pastes their own Google OAuth client id/secret, then connects — so the card
mirrors the WHOOP flow rather than the server-brokered Withings one.
- New POST /api/integrations/fitbit/test does a live, rate-limited
(5/60s per user) probe against the Google Health profile endpoint via
the refreshed token from getValidToken, returning { ok, latencyMs,
lastSyncedAt } and the same error-code union WHOOP uses. The Bearer
token and upstream host are scrubbed before any annotation.
- New POST /api/integrations/fitbit/resume clears a parked integration
via resumeIntegrationFromPark, rate-limited to match the test route.
- FitbitCard renders the credentials form, OAuth connect, sync now /
sync all data / test connection / disconnect action row, the parked
resume banner, and a backfill-in-progress line. Status reads from the
existing /api/fitbit/status; the pill/error/parked state comes off the
cross-integration envelope, which now carries a fitbit entry.
- Card strings added under settings.fitbit* across all six locales.
