From ac1226c367e3c3562c46efcffb2f6666cba54097 Mon Sep 17 00:00:00 2001 From: alvis Date: Fri, 15 May 2026 05:42:05 +0000 Subject: [PATCH] feat(integrations): migrate google-health from Fit REST to Google Health API v4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Google Fit REST API was closed to new sign-ups on 2024-05-01 and shuts down end of 2026, surfacing as "Access blocked: this app's request is invalid" when starting the OAuth flow. - Swap the 10 fitness.* OAuth scopes for the 3 googlehealth.*.readonly scopes (activity_and_fitness, health_metrics_and_measurements, sleep). - Replace fitness/v1 dataset:aggregate + sessions calls with health.googleapis.com/v4/users/me/dataTypes/{steps,total-calories, heart-rate,sleep}/dataPoints, filtered to today's window. - Read the v4 DataPoint union defensively (the per-type schema is sparsely documented) and log the first raw sample at debug so we can refine field paths after the first real OAuth. - Output Signal contract is unchanged — agents and downstream consumers see the same steps/activity/heart_rate/sleep signals. Cloud Console still needs: enable Google Health API, add the 3 scopes to the consent screen, add test user (all googlehealth scopes are Restricted).
