Reads continuous glucose data via the cgm_data scope, for users with an active Ultrahuman M1 CGM patch - individual readings (mg/dL, ~5-minute cadence), average glucose, glucose variability, estimated HbA1c, and time-in-target-range percentage. Surfaced through the same metrics endpoint, gated on the cgm_data scope. Available only when a user has an active patch.

title: Ultrahuman Partner (UltraSignal) API
description: >-
The Ultrahuman Partner API gives approved partners read access to
user-consented health metrics from the Ultrahuman Ring AIR / Ring Pro and,
for users with an active M1 patch, the Ultrahuman CGM. Access is secured with
OAuth 2.0 (Authorization Code Grant plus Refresh Token flow) across three
scopes: profile, ring_data, and cgm_data. Access is not self-serve - partners
apply to the developer program and are issued a Client ID, Client Secret, and
a registered redirect URI during onboarding; end users authorize data sharing
from the Ultrahuman app (Profile -> Settings -> Partner ID). Access tokens
expire in ~1 day (86400 seconds); refresh tokens rotate on each exchange.
IMPORTANT: This document is MODELED by API Evangelist from Ultrahuman's public
partner developer documentation. Endpoint paths, scopes, OAuth flows, query
parameters, and the documented metric families are drawn from the docs;
exact request/response schemas are approximations and should be verified
against the live developer portal. Ultrahuman also documents a personal-token
variant at GET /api/v1/partner/daily_metrics for a developer's own ring data.
