What is a payment gateway?

A payment gateway is a merchant service that authorises online payment processing for businesses. It lets businesses accept payment through their websites, providing a safe and reassuring user experience for customers wanting a quick yet secure payment option.

When customers make a purchase online using a payment gateway, their card information is sent to the credit card network where it is processed, and the payment information is then transferred back to the business along with whether the payment was authorised or not. If the payment is authorised, the order is completed.
