iZettle for Titanium
Latest commit 6cf28e7 Dec 31, 2012 @ejci Readme changes


iZettle library for Titanium

iZettle library for Titanium is a javascript module for Appcelerator Titanium. It allows to make card (VISA, Maestro,...) payments directly from your mobile device. Check how the whole system works on iZettle web page. It is very similar (same?) to Square but it works in Europe... well only in few EU countries (Sweden, Denmark, Finland, Norway, UK, Germany and Spain).

Example Usage

Check the example App to see it in action. It is ridiculously simple. You only need developer key from iZettle.

Titanium code:

//initialize module
var iZettle = new (require('modules/izettle'))({
    sourceUrl : 'izettlepoc', //your app URL scheme
    apiKey : 'MY_SECRET_API_KEY', //your api key from iZettle
    quiet : false, //debuging on=false/off=true

//create some button
var pay = Ti.UI.createButton({
    title : 'Pay with iZettle'
//do some action...
pay.addEventListener('click', function() {
    //iZettle call application with payment options
        price : 100.34,//price
        title : 'Payment title',//description
        currency : 'EUR',
        reference : 'REFERENCE_STRING',
        success : function(m) {
            //success callback
            alert('SUCCESS: ' + JSON.stringify(m));
        failure : function(m) {
            //failure callback :(
            alert('FAILURE: ' + JSON.stringify(m));

Titanium demo:

Demo App


I was unable to test payment proces with iZettle app. But according the documentation on their page iZettle app is using x-callback-url. So it was relatively easy to develop application even i didn't have access to their application.

To test callback from iZettle app i was using Safari browser. So here are the test link for Example App:

izettlepoc://iZettle/success?reference=YOUR_REFERENCE izettlepoc://iZettle/failure?reference=YOUR_REFERENCE&errorCode=TechnicalError izettlepoc://iZettle/failure?reference=YOUR_REFERENCE&errorCode=CancelledByUser izettlepoc://iZettle/failure?reference=YOUR_REFERENCE&errorCode=InvalidCurrency izettlepoc://iZettle/failure?reference=YOUR_REFERENCE&errorCode=InvalidState izettlepoc://iZettle/failure?reference=YOUR_REFERENCE&errorCode=MissingParameter

Just copy the links to Safari browser and press Go.

Demo App Safari testing

Of course in your application you will need to change URL scheme to your scheme.


Unfortunately I was unable to test it on real application because iZettle is not available in my country (Slovakia) :( But it should work... if not please contact me and I will try to help.
