CheckoutFinlandAPIForMeteorJS

Checkout Finland's Payment API Client for MeteorJS. PHP version of the client is available here https://github.com/rkioski/CheckoutAPIClient/ or here http://demo1.checkout.fi/xml2.php

TODO

Make a Meteor package of this

Requirements

Following packages are needed

$ meteor add jparker:crypto-md5
$ meteor add http
$ meteor add jparker:crypto-hmac
$ meteor add jparker:crypto-sha256

The response content is an xml data, so if you want to parse that data somehow, you could use for example a xml2js-package found here https://atmospherejs.com/peerlibrary/xml2js

Usage

Following example uses xml2js to parse the response data which is an xml and MomentJS to handle dates.

$ meteor add peerlibrary:xml2js
$ meteor add mrt:moment

Helper

Template.checkoutView.onCreated(function() {
    Meteor.call('getPaymentMethods', function(e, r) {
        if (e) {
            console.log(e);
            return false;
        }
        var pms = [];
        for (var bank in r) {
            var obj = {};
            for (var i in r[bank][0]) {
                if (i === '$') {
                    obj.url = r[bank][0][i].url;
                    obj.icon = r[bank][0][i].icon;
                    obj.name = r[bank][0][i].name;
                } else {
                    obj.fields = obj.fields ? obj.fields : [];
                    obj.fields.push({field: i, value: r[bank][0][i][0]});
                }
            }

            pms.push(obj);
        }

        Session.set('paymentMethods', pms);
    
    })

});
