Ionic Framework Paypal Payment Gateway

IK have developed a mobile app using ionic framework and cordova. In my backend mysql. and storing data using php code. Cordova Plugin ClientID here api keys.

 $scope.buyNow = function ()
    {
        PaypalService.initPaymentUI().then(function () { PaypalService.makePayment(50, "Total").then();       });
    }

PaypalService is implemented as

ngular.module('starter.PaypalService', ['starter.Constants'])
.factory('PaypalService', ['$q', '$ionicPlatform','Constants', '$filter', '$timeout', function ($q, $ionicPlatform, Constants, $filter, $timeout) {



    var init_defer;
    /**
     * Service object
     * @type object
     */
    var service = {
        initPaymentUI: initPaymentUI,
        createPayment: createPayment,
        configuration: configuration,
        onPayPalMobileInit: onPayPalMobileInit,
        makePayment: makePayment
    };


    /**

    function initPaymentUI() {

        init_defer = $q.defer();
        $ionicPlatform.ready().then(function () {

            var clientIDs = {
                "PayPalEnvironmentProduction": Constants.payPalProductionId,
                "PayPalEnvironmentSandbox": Constants.payPalSandboxId
            };
            PayPalMobile.init(clientIDs, onPayPalMobileInit);
        });

        return init_defer.promise;
    }

    /**

    function makePayment(total, name) {


        var defer = $q.defer();

        $ionicPlatform.ready().then(function () {

API Backend and Integrations

Every app talks to a server or backed and Appery.io provides a complete backend for your app:

Database - for storing app data.
Server Code - for writing app logic on the server using JavaScript.
API Express - exposing enterprise data sources such as an SQL database or SOAP service via REST APIs. Also, build advanced services with a visual service editor.
Push Notifications - send Push Notifications to your users.
