Payment Gateway API
A Payment Gateway API is a set of programming interfaces that allows developers to integrate payment processing functionality into applications, websites, or services. It handles the secure transmission of payment data between merchants, customers, and financial institutions, enabling transactions like credit card payments, digital wallets, and bank transfers. These APIs typically provide features for authorization, capture, refunds, and fraud detection.
Developers should learn Payment Gateway APIs when building e-commerce platforms, subscription services, or any application requiring monetization, as they provide a secure and compliant way to handle financial transactions without managing sensitive payment data directly. They are essential for ensuring PCI DSS compliance, reducing fraud risk, and offering multiple payment methods to users, which improves conversion rates and customer experience.
