Users.dataSources: create

Creates a new data source that is unique across all data sources belonging to this user.

A data source is a unique source of sensor data. Data sources can expose raw data coming from hardware sensors on local or companion devices. They can also expose derived data, created by transforming or merging other data sources. Multiple data sources can exist for the same data type. Every data point in every dataset inserted into or read from the Fitness API has an associated data source.

Each data source produces a unique stream of dataset updates, with a unique data source identifier. Not all changes to data source affect the data stream ID, so that data collected by updated versions of the same application/device can still be considered to belong to the same data source.

Data sources are identified using a string generated by the server, based on the contents of the source being created. The dataStreamId field should not be set when invoking this method. It will be automatically generated by the server with the correct format. If a dataStreamId is set, it must match the format that the server would generate. This format is a combination of some fields from the data source, and has a specific order. If it doesn't match, the request will fail with an error.

Specifying a DataType which is not a known type (beginning with "com.google.") will create a DataSource with a custom data type. Custom data types are only readable by the application that created them. Custom data types are deprecated; use standard data types instead.

In addition to the data source fields included in the data source ID, the developer project number that is authenticated when creating the data source is included. This developer project number is obfuscated when read by any other developer reading public data types. Try it now.

Request body

In the request body, supply a Users.dataSources resource with the following properties:

Property name Value Description Notes
Required Properties
application nested object Information about an application which feeds sensor data into the platform.
application.name string The name of this application. This is required for REST clients, but we do not enforce uniqueness of this name. It is provided as a matter of convenience for other developers who would like to identify which REST created an Application or Data Source.
dataType nested object The data type defines the schema for a stream of data being collected by, inserted into, or queried from the Fitness API.
dataType.field[] list A field represents one dimension of a data type.
dataType.field[].format string The different supported formats for each field in a data type.

Acceptable values are:
  • "blob"
  • "floatList"
  • "floatPoint"
  • "integer"
  • "integerList"
  • "map"
  • "string"
dataType.field[].name string Defines the name and format of data. Unlike data type names, field names are not namespaced, and only need to be unique within the data type.
dataType.name string Each data type has a unique, namespaced, name. All data types in the com.google namespace are shared as part of the platform.
device nested object Representation of an integrated device (such as a phone or a wearable) that can hold sensors.
device.manufacturer string Manufacturer of the product/hardware.
device.model string End-user visible model name for the device.
device.type string A constant representing the type of the device.

Acceptable values are:
  • "chestStrap"
  • "headMounted"
  • "phone"
  • "scale"
  • "smartDisplay"
  • "tablet"
  • "unknown"
  • "watch"
device.uid string The serial number or other unique ID for the hardware. This field is obfuscated when read by any REST or Android client that did not create the data source. Only the data source creator will see the uid field in clear and normal form.

The obfuscation preserves equality; that is, given two IDs, if id1 == id2, obfuscated(id1) == obfuscated(id2).

device.version string Version string for the device hardware/software.
type string A constant describing the type of this data source. Indicates whether this data source produces raw or derived data.

Acceptable values are:
  • "derived"
  • "raw"
