In the ever-expanding world of online commerce, setting up an eCommerce website involves navigating a myriad of technical terms and functionalities. One crucial aspect that often confuses business owners is the concept of a payment gateway. In this post, we’ll demystify what a payment gateway is, why it’s essential for your eCommerce site, and delve into popular examples like PayPal and Stripe.

Understanding the Payment Gateway

A payment gateway serves as the bridge between your online store and the financial institutions that process the payment. It facilitates the secure transfer of sensitive information, such as credit card details, ensuring a seamless and safe transaction for both the buyer and the seller.

Key Functions of a Payment Gateway

After authorization, the payment gateway transfers funds from the customer’s account to the merchant’s account.
