Migration Overview: Why Fitabase Is Moving to the Google Health API
Learn why Google is retiring the Fitbit Web API on October 30, 2026, why participants must reauthorize Fitabase, and what stays the same for your study.
Fitbit API to Google Health API Migration
What the move from the Fitbit Web API to the Google Health API means for your study: who must reauthorize, how to do it, key dates, and export changes.
Who Needs to Reauthorize
Find out which participants must reauthorize for the Google Health API: active, longitudinal, demo, and test accounts, versus those finishing before the cutoff.
How to Reauthorize Participants
Walk participants through Google Health API reauthorization in the Google Health app Partner apps screen or a Fitabase link, and track who needs to reconnect.
Reauthorizing Demo and Test Accounts
Reauthorize study-managed demo and test accounts yourself from the Requires reauthorization tab using Connect to Google Health and the account's credentials.
What Happens If a Participant Doesn't Reauthorize
See what happens when a participant misses the reauthorization deadline: past data is kept, new data pauses, and Fitabase backfills the gap once they reconnect.
Changes to Data Exports
Review how Fitabase exports change with the Google Health API: new UTC, time zone, and source columns, unchanged column names, and tips for export scripts.
Dataset Availability
See which Fitabase exports include Google Health API data today, which are delayed, which stay Fitbit API only, and which datasets are new in Google Health.
Sample Message for Participants
Use this sample email or script to tell participants they must grant Fitabase permission again, in the Google Health app or with their reauthorization link.
Key Dates and Timeline
Plan around key Google Health API migration dates: when reauthorization opens, the October 30 Fitbit Web API shutoff, and the November 30 reconnect window.
