Using Mercadopago Checkout

Create a Checkout preference:

var preference = {
        "items": [
            {
                "title": "Test",
                "quantity": 1,
                "currency_id": "USD",
                "unit_price": 10.5
            }
        ]
    };

mp.createPreference (preference, function (err, data){
        if (err) {
            console.log (err);
        } else {
            console.log (JSON.stringify (data, null, 4));
        }
    });

Get an existent Checkout preference:

mp.getPreference ("PREFERENCE_ID", function (err, data){
        if (err) {
            console.log (err);
        } else {
            console.log (JSON.stringify (data, null, 4));
        }
    });

Update an existent Checkout preference:

var preference = {
        "items": [
            {
                "title": "Test Modified",
                "quantity": 1,
                "currency_id": "USD",
                "unit_price": 20.4
            }
        ]
    };

mp.updatePreference ("PREFERENCE_ID", preference, function (err, data){
        if (err) {
            console.log (err);
        } else {
            console.log (JSON.stringify (data, null, 4));
        }
    });

Using Mercadopago Payment

Searching:

var filters = {
        "id": null,
        "site_id": null,
        "external_reference": null
    };

mp.searchPayment (filters, function (err, data){
        if (err) {
            console.log (err);
        } else {
            console.log (JSON.stringify (data, null, 4));
        }
    });

Receiving IPN notification:

var MP = require ("mercadopago"),
	http = require("http"),
	url = require('url');

var mp = new MP ("CLIENT_ID", "CLIENT_SECRET");

function onRequest(request, response) {
	var qs = url.parse (request.url, true).query;

	mp.getPaymentInfo (qs["id"], function (err, data){
        if (err) {
            console.log (err);
            response.writeHead(200, {
                'Content-Type' : 'application/json; charset=utf-8'
            });
            response.write (err);
            response.end();
        } else {
            console.log (JSON.stringify (data, null, 4));
            response.writeHead(200, {
                'Content-Type' : 'application/json; charset=utf-8'
            });
            response.write (JSON.stringify (data));
            response.end();
        }
    });
