Credit card payment plugin

Hi,

First, you need a contract with your bank or a payment gateway. Then, you need to configure a payment method with a plugin for this bank / payment gateway with the authentication information provided by the bank / payment gateway.
If it's with your bank, the money will go to your bank account. If it's a payment gateway, it will usually go to the merchant account on the payment gateway, and you can then transfer the money to your bank account with a bank transfer from the merchant account interface.
The easiest is to create a merchant account with PayPal:
www.paypal.com/lv/webapps/mpp/business
It can be done in minutes, and then you can use the PayPal Checkout payment plugin preinstalled with HikaShop to accept payments with it on your website, whether by credit card, PayPal account balance, etc.
