Payment Gateway APIs
Payment Gateway APIs are interfaces provided by third-party services that enable secure online payment processing for e-commerce websites, mobile apps, and other digital platforms. They handle sensitive financial transactions, including credit card processing, digital wallets, and alternative payment methods, while ensuring compliance with security standards like PCI DSS. These APIs abstract the complexity of payment infrastructure, allowing developers to integrate payment functionality without building it from scratch.
Developers should learn Payment Gateway APIs when building applications that require online transactions, such as e-commerce sites, subscription services, or donation platforms. They are essential for handling secure payment processing, reducing fraud risk, and complying with financial regulations, while saving development time compared to custom solutions. Specific use cases include integrating Stripe for subscription billing, PayPal for global e-commerce, or Square for in-person and online retail.
