GET /devices

Description

The /devices endpoint enables retrieval of a user's device information, including G4, G5, and G6 standalone receivers, the G5 and G6 mobile apps, and transmitters. The response is an array of all receiver-type devices contributing data to the specified time window, including the alerts and settings associated with each receiver.

Resource

GET /v2/users/self/devices

Authorization

OAuth 2.0 bearer token; see the Authentication section for details on this workflow.

Query Parameters

These query parameters specify the time window for the requested data; both are required. See the discussion of time in the Endpoint Overview section for more details on how they relate to device information. Due to the way device upload records are stored, the time components of the startDate and endDate parameters are ignored for the /devices endpoint.

Name	Type	Description
`startDate`	DateTime	Beginning of the time window
`endDate`	DateTime	End of the time window
