This script will access your Fitbit data via the Fitbit API and insert it into a Google spreadsheet.

/* FitbitDownload.gs
This script will access your Fitbit data via the Fitbit API and insert it into a Google spreadsheet.
The first row of the spreadsheet will be a header row containing data element names. Subsequent rows will contain data, one day per row.
Note that Fitbit uses metric units (weight, distance) so you may wish to convert them.

This worked great. Thanks for sharing. I am trying to tweak this code to pull down leaderboard information instead, but I'm running into some difficulties. Any chance you'd be willing to help create the script for use in a Google Spreadsheet to pull down the Leaderboard for all of my Friends on Fitbit? The API call is

http://api.fitbit.com/1/user/-/friends/leaderboard.json

Thanks for any help you can provide on this. I likely only need the sync() method as the rest of your script probably still applies.

Where does it actually save the authorization? I would like to be able to authorize multiple Fitbit accounts.

Starting on line 43, how can I fix the error: "Script is using OAuthConfig which has been shut down. "?
