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).
