iZettle for Titanium Appcelerator

Yesterday I was bored and by browsing the web I found iZettle.
So I decided to make a Titanium library for mobile application payments. It wasn’t complicated and I was surprised that no one created this before me (at least I didn’t find anything).

I really like the idea of iZettle. It’s actually a copy of Square for Europe. Unfortunately it doesn’t work in my country, so I was unable do end to end testing. But I am convinced that it will work out of the box because it is very very simple.

Basically what you need is to open iZettle app from your app with parameters like: price, payment title, callback urls. After iZettle processes payment, it will call your app with callback url. So your app only needs to now how to call iZettle app and have some sort of url listener for callback calls from iZettle app.

My library wraps this whole process and does everything for you. You only need to include my library and pass parameters to payment method. And thats it 🙂

Sample usage

Check the example app to see it in action. It is ridiculously simple. You will need a api key from iZettle.

//initialize module
var iZettle = new (require('modules/izettle'))({
	sourceUrl : 'izettlepoc', //your app URL scheme
	apiKey : 'MY_SECRET_DEV_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 paym,ent options
		price : inputPrice.getValue(),
		title : inputDescription.getValue(),
		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));

    Also consider using SumUp’s API for mobile payments. SumUp is basically the Square of continental Europe, being market leader in Germany, Spain, Italy, France and so on and so forth while iZettle is mostly present in the Nordics..

      Api looks very similar to api from iZettle. I will definitely create a library for SumUp.
      Thanks for letting me know.
