Versioning.
2026.08
- The Fitbit ecosystem is transitioning fully to Google Health. Google Health is now available in the Device Data API (V2) and data collected from Fitbit devices will be available there. The Fitbit-specific API and SDK methods are deprecated. See the migration guide for more details on this transition.
2026.03
- You can now upload and delete participant files from the REST API.
- You can now get and update export configurations.
- The Projects API now lets you download full project details (including notifications, surveys, etc.) and selectively import project modules from one project into another.
- New SDK version 5.5.0 contains some minor bugfixes.
2025.12
- New SDK version 5.3.1 added.
- You can now open a secondary view through the SDK.
- Survey tasks, answers, and results now support survey events.
- getExternalAccountProviders now returns information about whether a provider is enabled for a participant.
- Oura data is now supported in the device data API and SDKs.

- You can now pass detailed options when starting a survey.
2025.06
- New SDK version 4.3.0 added. The major version number changed to distinguish new versions (which target
es2021) from old versions (which target es6), but the 4.x SDK is backwards-compatible with the 3.x SDK.
- The SDK now allows you to prompt for Health Connect Personal Health Record (PHR) permissions from within the MyDataHelps Android app.
- The Participants API now lets you query by selected demographic fields.
- Participant Queries now let you specify sort order even if you’re not using a segment. The old
segmentSortBy and segmentSortAscending fields are still supported for backwards-compatibility, but you should use sortBy and sortAscending moving forward.
- The API and SDK now allow you to query for survey results.
- Device Data V1 now supports a query for available data types in the API and SDK.
2025.03
- New SDK version 3.27.0 added.
- Google Health Connect is now supported in the Device Data APIs/SDKs. In particular, the SDK contains methods for prompting the participant to configure Health Connect from within the MyDataHelps Android app.
- REST API calls now perform stricter type validation, particularly around identifiers. If you are receiving 400 errors (Bad Request), check that your API calls are sending valid parameters.
2024.10
- New SDK version 3.24.0 added.
- The SDK now supports a
queryDeviceDataV2DailySleep method to query aggregated sleep data.
- You can now get a list of all queryable device data types for Device Data API V2 namespaces via the API and SDK.
- Device data queries now support querying by
properties and dataSource for device-specific metadata.
- Survey tasks now support querrying by survey category.
- The
openExternalUrl and openEmbeddedUrl SDK navigation methods are now available in Web View steps.
- You can now manage your project’s saved Export Explorer queries through the Exports API.

2024.05
2023.10

- New properties,
isMainSleep and logType now exist in the Fitbit sleep log in the REST API and SDK. These fields will only be populated in newly polled data.
- When querying the Participant API for a specific segment, the query now returns the date when each participant was added to the segment.
- The Survey API and SDK now return the survey category when querying tasks.
Deprecation Notice: Secondary Identifier
The participant secondaryIdentifier field is being deprecated as a first-class identifier within MyDataHelps. Any existing secondary identifiers will be migrated to a custom field named SecondaryIdentifier. For backwards compatibility, the API/SDK secondaryIdentifier will just be an alias for that custom field.

2023.02
