Look Up value through REST without select or expand

Question

Can we get the lookup value from SharePoint list through REST without using the query operators (select/expand) ?

Answer 1

You can use the RenderListDataAsStream endpoint to fetch lookup values without using select or expand. This works for User fields as well as Managed metadata columns as well.

Try with the below sample code:

$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + 
        "/_api/Web/Lists/GetByTitle('Documents')/RenderListDataAsStream",
    type: "POST",   
    headers: {
        Accept: "application/json;odata=nometadata",
        "Content-Type": "application/json;odata=nometadata",
        "X-RequestDigest": $("#__REQUESTDIGEST").val()
    },
    success:function(data){
        // iterate over data.Row
        console.log(data.Row);
    },
    error:function(data){
        console.log(data);
    }
});
