Credit and debit cards

1. In the store Control Panel, go to Stores > Configuration > Sales > Payment Methods.
2. In the Mercado Pago plugin, click Configure.
3. Click on the Checkout Transparent tab and then click on Credit and debit cards and fill in the fields according to the descriptions below.
   1. In Enabled, choose between "Yes" or "No". This option sets whether the payment method will be available for use.
   2. In Title, set the title of how the payment method will be displayed on the store checkout.
   3. In Enable vault, select to allow the consumer to save or use the card in the future.
   4. In the Payment Action field, select between Authorization for future capture or Authorization for immediate capture. This setting will define the behavior of how Mercado Pago will process the order, with "Authorization for immediate capture" being a flow that requires no future action, in this scenario the customer pays and Mercado Pago already withdraws the amount from the card balance. For the option "Authorization for future capture" Mercado Pago will only sensitize the value in the customer's balance and only after their manual action will the value be captured in fact.
   5. In Use Binary Mode, select between Yes, Processed Order Synchronous or No, Processed Order Asynchronous. This field defines whether to accept only payments where the final status is received immediately.

In this section, you can define some general characteristics of the platform for the use of Checkout API. Fill in each of the requested fields according to the description below.

1. In the Minimum order total option, set the minimum value for an order to be processed. In this field, enter integers. The payment method will only be displayed to the consumer if the order value is equal to or greater than what you inform.
2. In Maximum order amount, set a maximum value for the order to be processed. In this field, enter integers. The payment method will only be displayed to the consumer if the order value is equal to or less than what you inform.
3. In Payment From Specific Countries, select the countries that can use this payment method. Only consumers whose payment address is from one of the countries you selected can see this payment method.
4. In the Sort Order option, set an ascending order of display for this payment method on the checkout. The lower the number you enter, the lower the position of this payment method among all others. For example, if it is 1, any other payment method with a higher order will be displayed after it.
