Two connect-in-app enhancements for the native client.
return_scheme: GET /api/whoop/connect accepts an optional custom scheme,
threaded through the server-side OAuth-state row so it survives the round
trip without ever riding in the URL or cookie. When a valid scheme is
present, the callback's final redirect targets <scheme>://whoop?whoop=
connected|error&reason=... so an in-app web session auto-completes on its
custom-scheme match; absent or invalid, the web settings redirect is
unchanged. Schemes validate against a strict allowlist (custom app scheme
only, ^[a-z][a-z0-9.+-]*$, http/https/javascript/data/file/vbscript
rejected, pinned to dev.healthlog.app). A rejected scheme falls back to
the web redirect and never reflects an arbitrary value.
Bearer connect ticket: a purely Bearer-authenticated client holds no web
session cookie, so it cannot start the handshake through the cookie-gated
connect route. POST /api/whoop/connect/ticket (Bearer) mints a one-time,
~60s, opaque ticket bound to the user; only its HMAC-SHA256 hash is stored
(the raw value never persists). GET /api/whoop/connect?ticket=<opaque>
accepts the ticket in lieu of a cookie, consumes it atomically (single-use,
reuse rejected), sets the nonce cookie, and 302s to WHOOP exactly as the
cookie path. Expired, consumed, or invalid tickets return a typed 401. The
two combine. The daily WHOOP OAuth-state cleanup also sweeps expired ticket
rows.
The ticket query param is added to the egress redaction denylist so the
opaque value never reaches logs or error reports.
Migration 0124 adds whoop_connect_tickets (id, user_id FK cascade,
token_hash unique, expires_at, consumed_at, created_at) and a nullable
return_scheme column on whoop_oauth_states.
