  • Brazil: https://www.mercadopago.com/mlb/ferramentas/aplicacoes
  • México: https://www.mercadopago.com/mlm/herramientas/aplicaciones
  • Venezuela: https://www.mercadopago.com/mlv/herramientas/aplicaciones
  • Colombia: https://www.mercadopago.com/mco/herramientas/aplicaciones

var MP = require ("mercadopago");

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

Promises and Callbacks support

Every method supports either promises and callbacks. For example:

var at = mp.getAccessToken ();

at.then (
    function (accessToken) {
        console.log (accessToken);
    },
    function (error) {
        console.log (error);
    });

is the same as:

mp.getAccessToken(function (err, accessToken){
    if (err) {
        console.log (err);
    } else {
        console.log (accessToken);
    }
});

In order to use callbacks, simply pass a function as the last parameter.

Get your Access Token:

mp.getAccessToken();

Using MercadoPago Checkout

Create a Checkout preference:

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

mp.createPreference (preference);

Others items to use

Get an existent Checkout preference:

mp.getPreference ("PREFERENCE_ID");

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);

        "id": null,
        "site_id": null,
        "external_reference": null
    };

                });

Cancel (only for pending payments):

mp.cancelPayment ("ID");

Refund (only for accredited payments):

mp.refundPayment ("ID");

Generic resources methods

You can access any other resource from the MercadoPago API using the generic methods:

// Get a resource, with optional URL params. Also you can disable authentication for public APIs
mp.get ("/resource/uri", [params], [authenticate=true]);

// Create a resource with "data" and optional URL params.
mp.post ("/resource/uri", data, [params]);

// Update a resource with "data" and optional URL params.
mp.put ("/resource/uri", data, [params]);

For example, if you want to get the Sites list (no params and no authentication):

mp.get ("/sites", null, false)
    .then (function (sites) {
        console.log (sites);
    });
