Test cards
Mercado Pago provides test cards that will allow you to test payments without using a real card.
Their data, such as number, security code, and expiration date, can be combined with the data relating to the cardholder, which will allow you to test different payment scenarios. That is, you can use the information of any test card and test different payment results based on the cardholder's data.
Below, you can see the data of the test debit and credit cards. Select the one you want to use to test your integration.
