Activity Time Series

The Activity Time Series endpoints are used to query a Fitbit user's activity data over a period of time, either by specifying a date and time period, or a date range. The response will return only the daily summary value over the specified date range for the given resource. The Activity Time Series endpoints support returning Intraday data (see Intraday).

The endpoints available in this section are

  • Get Activity Time Series by Date retrieves the activity data for a given resource over a period of time by specifying a date and time period. The response will include only the daily summary values.
  • Get Activity Time Series by Date Range retrieves the activity data for a given resource over a period of time by specifying a date range. The response will include only the daily summary values.
