Using Mercadopago Checkout

Create a Checkout preference:

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

mp.createPreference (preference)
	.on ("ok", function (pref){
		console.log (JSON.stringify (pref, null, 4));
	})
	.on ("error", function (error){
		console.log ("ERROR: " + error);
	});

Get an existent Checkout preference:

mp.getPreference ("PREFERENCE_ID")
	.on ("ok", function (pref){
		console.log (JSON.stringify (pref, null, 4));
	})
	.on ("error", function (error){
		console.log ("ERROR: " + error);
	});

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)
	.on ("ok", function (pref){
		console.log (JSON.stringify (pref, null, 4));
	})
	.on ("error", function (error){
		console.log ("ERROR: " + error);
	});

Using Mercadopago Payment collection

Searching:

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

mp.searchCollection (filters)
	.on ("ok", function (result){
		console.log (JSON.stringify (result, null, 4));
	})
	.on ("error", function (error){
		console.log ("ERROR: " + error);
	});

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"])
		.on ("ok", function (result){
			console.log (JSON.stringify (result, null, 4));

			response.writeHead(200, {
				'Content-Type' : 'application/json; charset=utf-8'
			});
			response.write (JSON.stringify (result));
			response.end();
		})
		.on ("error", function (error){
			console.log ("ERROR: " + error);
			
			response.writeHead(200, {
				'Content-Type' : 'application/json; charset=utf-8'
			});
			response.write (JSON.stringify (error));
			response.end();
		});
