Scenario: I have one Site Collection in abc.com domain and other Site Collection I have inside xyz.com domain. Now I want to access list item from abc.com domain inside xyz.com domain. Both Sites are created in Office 365. I tried with JSOM and REST api but it fails while making call.

Please advice with code sample.


  • Call to another domain not working, try JQuery JSONP stackoverflow.com/questions/7409155/…

Make sure the two site collection in a same tenant and use have permission to get list data from another site collection.

<script src="https://code.jquery.com/jquery-1.12.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
    var siteCollUrl="https://xxx.sharepoint.com/sites/lz";
    var listName="CustomList";
        url: siteCollUrl + "/_api/web/lists/getbytitle('"+listName+"')/items",
        type: "GET",
        headers: {
            "Accept": "application/json;odata=verbose",
        success: function (data) {
            var titles="";
        error: function (data) {
