Include saved cards

Client-Side

In order for Payment Brick to be able to display the saved cards of a given buyer, it is necessary to send the customer ID and card IDs to Brick at the time of its initialization, as in the example below.

          
settings = {
   initialization: {
       ...,
       payer: {
           ...,
           customerId: '209277402-FqRqgEc3XItrxs',
           cardsIds: [ '1518023392627', '1518023332143' ]
       },
   },
   ...
}

        
          
const initialization = {
 ...,
 payer: {
   ...,
   customerId: '209277402-FqRqgEc3XItrxs',
   cardsIds: [ '1518023392627', '1518023332143' ]
 },
};

        

Just passing these two properties, Brick will automatically give the user the option to make the payment with their saved cards.

Attention
Only no expired cards will be shown to the buyer, expired cards will not be made available.
