Hi Marc...

So, as the last discussion item I opened indicates, I have been playing with GetListItemChangesSinceToken, which may soon replace my use of GetListItems... This method (GetListItemChangesSinceToken) works fine in SP2010 and 2013, but is failing for me when I try it in SP2007...

Below I have the request and response (XML) along with the SPServices call I'm issuing... I know this, is is against 2007.. I'm hopping you may still have an environment to try this on...

Request:

SPServices:

$().SPServices({
    operation: 'GetListItemChangesSinceToken',
    listName: 'PaulTestList',
    completefunc: function(xData, status){
        console.log('back!');
    }
})

XML Request:
