> [!WARNING] > **Warning:** The Google Fit APIs, including the Google Fit REST API, will be deprecated in 2026. As of May 1, 2024, developers cannot sign up to use these APIs. We recommend migrating to the [Google Health API](https://developers.google.com/health) for cloud-based integrations or [Health Connect](https://developer.android.com/health-and-fitness/health-connect) for step tracking and mobile-first Android apps. For instructions on which API or platform to migrate to, see the [Fit migration guide](https://developer.android.com/health-and-fitness/health-connect/migration/fit).  **Figure 1**: Google Fit REST API. The Google Fit REST API enables you to store and read health and wellness data in the [fitness store](https://developers.google.com/fit/overview#components) from apps on any platform. The REST API provides resources and methods to: - Create, obtain, list, and modify **data sources**. A data source represents a unique source of sensor data. All health and wellness data in the fitness store is associated with a particular data source. - Create, obtain, aggregate, and delete **datasets**. A dataset represents a set of data points from a particular data source. - List **data points** and add them to a dataset. A data point represents a sample from a particular data source. - Create, list, and delete **sessions**. A session represents a time interval with associated metadata.
