Working with Datasets

The Fitness REST API lets you create, obtain, and add points to datasets. A dataset represents a set of data points from a particular data source.

Datasets are represented by the Users.dataSources.datasets resource.

Add points to a dataset

This example demonstrates how to add ten new step count delta points to a previously empty dataset. This example assumes that you created a data source as described in Managing Data Sources.
