In a SharePoint Hosted App, with the following code, I can retrieve the list of tasks, every task containing, among others, the identifiers AssignedToId (an array of integers):

    url: appweburl + "/_api/SP.AppContextSite(@target)/web/lists' +
        '/getByTitle('MyTasks')/items?@target='" + hostweburl + "'",
    method: "GET",
    headers: { "Accept": "application/json; odata=verbose" },
    success: successHandler,
    error: errorHandler

Instead of the identifier of the users, I want to show the titles of the persons. I can retrieve the title through GetUserById(1) or GetUsers, but this leads to an additional AJAX call I want to avoid.

Is there a way to retrieve this information in a single call?

Note that you need to $select all the fields you need when using $expand like this.

  • Nice! I thought $expand can be applied to values only, not arrays of values. Apr 1, 2015 at 10:24
