Compatible browsers
Important
It is important to note that while Internet Explorer 11 is compatible with some
Checkout API,
flows, the browser is not officially supported by Mercado Pago.
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).
