Payment gateway: What is it and how to choose one?

An ecommerce payment gateway is a payment gateway designed for online stores. It is a payment gateway for your website or mobile app that accepts digital payments at checkout, routes transactions for authorization, and supports security controls that help protect customer data.

An international payment gateway supports multiple countries and currencies, often with localization features such as local payment methods, region-specific authentication flows, and multi-currency settlement options.

A secure payment gateway typically uses encryption and tokenization to protect payment data and supports authentication and risk controls. The exact security requirements depend on your payment methods, regions, and implementation.

Most teams integrate a payment gateway using APIs or plugins. Using plugins and hosted payment gateways can help you integrate faster. If you have the engineering time to spare, you can also customize the payment gateway experience and embed it directly into your website or app.
