Retroactive Fitbit Data from lost API account

[QuantuProject]

If our API account is lost can we create a new developer account, that has an individuals third party access consent and access data from prior Fitbit usage?

Hi @QuantuProject,

I am assuming this is in regard to your previous threads regarding the lost Client Id. Data is tied to the access token from the user that authorized your application to access their data based on the scopes they've selected in the authorization page.

If you have a new client ID, your users will need to go through the new authorization process again before you can pull their data. Fortunately, you can extract all of the same historical data that your previous client ID had by querying the same endpoints you used in the last application. 

I know there might be a lot of data you may need to pull again, so to avoid hitting our rate limit of 150 API calls per user per hour, you can use our time series endpoints to extract data from specific date ranges in a single call:

• https://dev.fitbit.com/build/reference/web-api/activity/#get-activity-intraday-time-series
• https://dev.fitbit.com/build/reference/web-api/heart-rate/#get-heart-rate-time-series

I hope this helps. Let me know if you have any additional questions.
