Payment gateways function as a virtual point-of-sale terminal for both online and offline transactions during a purchase on a website. Technically speaking, it’s an infrastructure that allows a customer, a merchant, and a payment processor to exchange payment details securely.
Consider it a secure tunnel that encrypts private information, such as credit card numbers, while a purchase is being made.
How does a payment gateway work?
Consider a payment gateway as the back-end mechanism that enables online transactions. Here is a simplified view:
- The buyer starts the transaction: Using a website or app, the buyer chooses what they want and checks out.
- Payment information is entered: Credit card information or other payment details are entered by the client. The website encrypts this sensitive data.
- Transaction request is sent: The encrypted data is transmitted to the payment gateway along with a transaction request.
- Gateway routes the transaction: The gateway directs the transaction: The payment gateway routes the transaction data to the payment processor while serving as a safe middleman.
- Payment processor contacts the card network: The card network is contacted by the payment processor. The transaction data are sent to the relevant card network (Visa, Mastercard, etc.) via the payment processor.
- Authorization request: The customer’s bank receives an authorization request from the card network.
- Bank accepts or rejects: Depending on available finances and other considerations, the customer’s bank may accept or reject the transaction.
- Response is relayed: The payment processor receives the bank’s response via the card network before sending it to the payment gateway.
- Merchant receives the response: The payment gateway notifies the merchant of the transaction status (authorized or rejected).
- The transaction is finished: The merchant completes the order if it is accepted.

Payment Gateway Types
There are three primary categories of payment gateways that you can select from based on your technological capabilities and business requirements:
Hosted gateways: For companies with minimal technical resources, hosted gateways are the most convenient choice. Implementation is only adding a button or link to your website that takes users to the platform of the payment service provider to finish their transaction. This gives you less control over the checkout process but requires very little technological preparation.
Self-hosted gateways: This option allows your company to handle the data collection and payment interface on your website. Although this gives you more control over the consumer experience, the initial setup and integration call for a high level of technical competence. Additionally, you will be more accountable for adhering to security regulations.
API-hosted gateways: Implementing these gateways, especially for performing API calls and managing answers within your own application, requires technical expertise. They do, however, provide a balance between ease and control, letting you personalize the payment process while taking advantage of the provider’s safe infrastructure.
