            var restAuthHeader = btoa($('UserName').val() + ':' + $('UserToken').val());
            request.withCredentials = true;
            request.setRequestHeader("Authorization", "Basic " + restAuthHeader);
        },
        url: 'https://api.connectionsonline.net/v4/projects',
        type: 'GET',
        dataType: 'json',
        success: function (data) {
            // Do something with the data.
        },

            // Do something with the error.
        }
    });
