var records = [{data:'data1'}, {data:'data2'}];
async.eachSeries(records, function (record, cb) {
// this was inside an angular project, but use whatever ajax call you want here
    $http.post('http://myurltopost', record).
        success(function (data, status, headers, config) {
            cb(null, data);
        })
        .error(function (data, status, headers, config) {
            // called asynchronously if an error occurs
            // or server returns response with an error status.
            cb('error', null);
        });
    }
, function (e) {
    resolve(response);
});
