Get work items

After executing a query, get the work items using the IDs that are returned in the query results response. You can get up to 200 work items at a time.

A flat query

1. Get results of a flat work item query.

Sample request

POST https://mytfsserver/DefaultCollection/_apis/wit/wiql?api-version=1.0

{
  "query": "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.WorkItemType] = 'Task' AND [State] <> 'Closed' AND [State] <> 'Removed' order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc"
