MercadoPago.js V2

Version 2 of the client-side SDK has functions based on Promises. In addition, it has a renewed interface for developers and handles errors more efficiently.

Fraud prevention This version has a functionality that, based on the analysis of the buyer's behavior, identifies if a transaction is fraudulent or suspicious. This analysis is intended to improve the approval of payments. If you wish, you can turn off this feature. Check our [technical reference](https://github.com/mercadopago/sdk-js#api).

To install the frontend SDK, you must include MercadoPago.js in the HTML of your application, as shown in the code below.

          
<script src="https://sdk.mercadopago.com/js/v2"></script>

        

Then, you must add the Public Key of the account you are integrating so that it can be identified when connecting to Mercado Pago.

          
const mp = new MercadoPago('YOUR_PUBLIC_KEY');
