Customize the payment preference
If necessary, when creating the payment preference on your server, you can specify restrictions such as specific exclusions of payment methods or types and set the maximum or the default number of installments.
Exclude Payment Methods
You can specify the types of payment method you do not want to accept (Cash, Credit or Debit Cards) by excluding them when creating the Checkout Preference.
In the content of the payment preference, you can add the payment methods or types of payment methods that you do not want to accept.

"payment_methods": {

}You can even determine which specific payment methods (Visa, Mastercard, etc.) you want to exclude from the checkout:
