here is an article on what is a payment gateway and how it works for your online store:

What is a Payment Gateway?

A payment gateway is a service that allows businesses to accept payments online. When a customer wants to make a purchase from your online store, they will enter their payment information into a form on your website. The payment gateway will then encrypt this information and send it to the customer’s bank or credit card company for processing. If the payment is approved, the funds will be transferred from the customer’s account to yours.

How Does a Payment Gateway Work for Your Online Store?

When a customer wants to make a purchase from your online store, they will be taken to a checkout page. On this page, they will enter their payment information, including their credit card number, expiration date, and CVV code. They will also be asked to enter their billing address and shipping address.

Once the customer has entered their payment information, they will click on the “Pay Now” button. This will send their payment information to the payment gateway. The payment gateway will then encrypt this information and send it to the customer’s bank or credit card company for processing.

If the payment is approved, the funds will be transferred from the customer’s account to yours. The customer will then be taken to a confirmation page, where they will be able to print out a receipt for their purchase.
