With the Checkout API, offer payments with credit or debit cards (available in the country where the store is installed) directly in your store, without the buyer needs to be redirected to make the payment.

To integrate the payment method, follow the steps below.

  1. Go to the Stores > Configuration > Sales > Payment Methods menu.
  2. To activate card payments, access the Mercado Pago > Custom Checkout - Credit and Debit Card section.
  3. Select Yes to activate the Mercado Pago experience for card payments at your store checkout. By default, the card payment method is already activated.
  4. If necessary, change the title of the payment method that will appear for the buyer.
  5. In the Statement Descriptor field, enter the text that will identify the payment on the card statement. This feature is not available in all countries.
