Third-Party Payment Gateways
Third-party payment gateways are external services that securely process online payments between customers and merchants, handling tasks like transaction authorization, fraud detection, and fund settlement. They act as intermediaries between e-commerce platforms, mobile apps, or websites and financial institutions, ensuring compliance with payment card industry (PCI) standards. Examples include Stripe, PayPal, and Square, which simplify integration and reduce the burden of managing payment infrastructure.
Developers should use third-party payment gateways when building applications that require secure, reliable online transactions, such as e-commerce sites, subscription services, or donation platforms, to avoid the complexity and liability of handling sensitive payment data directly. They are essential for ensuring PCI compliance, reducing fraud risk, and speeding up development by providing pre-built APIs and SDKs for various payment methods like credit cards, digital wallets, and bank transfers. This allows teams to focus on core product features rather than payment processing logistics.
