Getting permission to read and write health data

To read health data, follow these steps:

Make sure your app complies with Google's API User Data Policy and the Google Fit Developer and User Data Policy.
Apply for your consent screen to be verified by Google.

Note: If your app isn't verified when it requests access to a sensitive OAuth scope, Google will assess its risk and apply quotas accordingly. Your users might also see warning screens. You can still test your app but the quotas will restrict how many new users you can get.

If your app gets verified, it can read health data that users have consented to being read.

Health data types Stay organized with collections Save and categorize content based on your preferences.
