Hello!
Now I am paying for payment in the online store, you need to make it so that the user can replenish his balance with any credit card, while the money must also be transferred to a credit card (master card). Payment must be made automatically, i.e. the user transferred the money and the product was immediately added to him. For this, for example, in webmoney or Yandex money, http-notifications were made, but they charge a fee there, I’m wondering if you can also do it with a credit card, i.e. so that for any account replenishment a notification is sent to my server?
