Parse.initialize("YOUR_APP_ID", "YOUR_JS_KEY"); //PASTE HERE YOUR Back4App APPLICATION ID AND YOUR JavaScript KEY
Parse.serverURL = "https://parseapi.back4app.com/";

Find your Application ID and your Client Key

  1. Go to your App Dashboard at Back4App website.
  2. Navigate to app’s settings: Click on Server Settings > Core Settings block > Settings.
