HTTP request

To begin tracking changes, you make a request including the delta function on the device resource.

GET /devices/delta

Query parameters

Tracking changes incurs a round of one or more delta function calls. To use any query parameter other than $deltatoken and $skiptoken, you must specify it in the initial delta request and Microsoft Graph automatically encodes any specified parameters into the $deltatoken portion of the @odata.nextLink or @odata.deltaLink URL provided in the response.

Query parameter Type Description
$deltatoken string A state token returned in the @odata.deltaLink URL of the previous delta function call for the same resource collection, indicating the completion of that round of change tracking. Save and apply the entire @odata.deltaLink URL including this token in the first request of the next round of change tracking for that collection.
$skiptoken string A state token returned in the @odata.nextLink URL of the previous delta function call, indicating that there are further changes to be tracked in the same resource collection.

Optional query parameters

This method supports OData query parameters to help customize the response.

  • You can use the $select query parameter to specify only the properties your need for best performance. The id property is always returned.
  • There is limited support for $filter. The only supported $filter expression is for tracking changes for specific resources, by their ID: $filter=id+eq+'{value}' or $filter=id+eq+'{value1}'+or+id+eq+'{value2}'. The number of IDs you can specify is limited by the maximum URL length.

Request headers

Authorization Bearer {token}. Required. Learn more about authentication and authorization.

Request body

Don't supply a request body for this method.

Response

If successful, this method returns a 200 OK response code and a collection of device objects in the response body. The response also includes a @odata.nextLink URL or a @odata.deltaLink URL.

  • If a @odata.nextLink URL is returned, there are additional pages of data to be retrieved in the session. The device continues making requests using the @odata.nextLink URL until a @odata.deltaLink URL is included in the response.
  • If a @odata.deltaLink URL is returned, there is no more data about the existing state of the resource to be returned. Persist and use the @odata.deltaLink URL to learn about changes to the resource in the future.
