How to update a multiple lookup field in SharePoint Designer 2013 (REST API)

I would like to update a multiple lookup field in SharePoint Designer 2013. OOTB this is not possible. In SharePoint Designer 2010 it was possible. Now I would like to do this with for example a REST API call in the SharePoint Designer 2013 workflow. How can I do this?

UPDATE
I try first to make it work in javascript but it is not working yet. What I am doing wroning in this script?

<script src="https://code.jquery.com/jquery-1.11.1.min.js" type="text/javascript"></script><script type="text/javascript">

$(document).ready(function(){

//replace your list title

$.ajax({
    url: "https://myCompany.sharepoint.com/sites/DMS-WF-Test-Infra/_api/web/lists/getByTitle('TestKH')/items(5)",
    type: "POST",
    contentType: "application/json;odata=verbose",
    data: JSON.stringify({
         '__metadata': {
            'type': 'SP.Data.TestKHListItem',
         },
         'SBSId': { "results": [1,2] }
    }),
    headers: { 
          "Accept": "application/json;odata=verbose",
          "X-RequestDigest" : $("#__REQUESTDIGEST").val(),
          "X-HTTP-Method": "PATCH",
           "If-Match": "*"
       },   
    success: function (data) {
        console.log("done");
    },
    error: function (err) {
        console.log(JSON.stringify(err));
    }
});

})

</script>​​

'ColumnNameId': {"results": [59, 60] }
