Workflow to duplicate list item in the same list with SP 2013

Question

I need to create a workflow that simply duplicates a list item and adds it to the same list. (when item is created). I know that there is the function in SP Designer 2010, but Im not allowed to use this functionality since I should create it with SP Designer 2013 only. Is there a good workaround for that? Best solution would be a web service to do it, but im not that familiar with it. I think this articel leads to the right direction, but there is still something missing and Im not 100 % sure what it is actually doing.

Not Workflows but JSOM code

Get the ID of the item you want to clone (in the current context) and execute:

function cloneItem(id) {
    var c = new SP.ClientContext.get_current(),
        l = c.get_web().get_lists().getById(SP.ListOperation.Selection.getSelectedList()),
        i = l.getItemById(id),
        f = l.get_fields(),
        n, e, d, m, v,
        url = _spPageContextInfo.serverRequestPath;
    c.load(i);
    c.load(f);
    c.executeQueryAsync(
        function () {
            n = l.addItem(new SP.ListItemCreationInformation());
            e = f.getEnumerator();
            while (e.moveNext()) {
                d = e.get_current();
                m = d.get_internalName();
                if (!(d.get_readOnlyField() 
                       || d.get_hidden() 
                       || ['Attachments', 'ContentType'].indexOf(m) > -1)
                   ) {
                    v = i.get_item(m);
                    if (v) n.set_item(m, v);
                }
            }
            n.update();
            c.load(n);
            c.executeQueryAsync(function () {
                document.location = url.substr(0, url.lastIndexOf('/')) 
                                     + '/EditForm.aspx?ID=' + n.get_id();
            })
        })
}

Executes it from a List View:

Answer 2

If I understood correctly you would like to create the same item via a Workflow in the same list?

Then you can select under Actions -> Create New List Item -> and then just set Title and all you columns to the current item and the field.

No need to work with REST here.

Do not forget to check the box "Run on item created"
