To ensure a secure integration that protects the data of every transaction, it is essential to implement an SSL (Secure Sockets Layer) certificate. This certificate, together with the use of the HTTPS protocol when providing payment methods, guarantees an encrypted connection between the client and the server.

Adopting these measures not only strengthens the security of user data, but also ensures compliance with the specific regulations and laws of each country regarding data protection and information security. In addition, it significantly contributes to providing a safer and more reliable shopping experience.

Although the SSL certificate is not required during the testing period, its implementation is mandatory for production.

For more information, see the Mercado Pago Terms and Conditions.
