How to use this in ionic?

You can post data using Parse REST API like this. Hope this helps.

$http({
    method: 'POST',
    url: 'https://api.parse.com/1/classes/shifts',
    data: {
          columnName: 'value',
          columnName: 'value'
    },
    headers: {
        'X-Parse-Application-Id': '',
        'X-Parse-REST-API-Key': '',

    }
})
.success(function (data, status) {

})
.error(function (data, status) {

});
