Third-Party Payment Processors
Third-party payment processors are external services that handle online payment transactions for businesses, securely processing credit cards, digital wallets, and other payment methods. They manage the technical and compliance aspects of payments, including encryption, fraud detection, and settlement, allowing developers to integrate payments without building a full payment infrastructure from scratch. Examples include Stripe, PayPal, and Square.
Developers should use third-party payment processors when building e-commerce sites, subscription services, or any application requiring secure online payments, as they reduce PCI DSS compliance burdens and speed up development. They are essential for handling complex payment flows, supporting multiple currencies, and ensuring transaction security in global applications.
