Square Web Payments SDK
The Square Web Payments SDK is a JavaScript library that enables developers to securely integrate Square's payment processing capabilities into web applications. It provides pre-built UI components and APIs for handling credit card payments, digital wallets, and other payment methods without handling sensitive payment data directly. This helps businesses accept payments online while maintaining PCI compliance.
Developers should use this SDK when building e-commerce websites, online stores, or any web application that requires payment processing, especially if they are already using Square's ecosystem for point-of-sale or other services. It simplifies the implementation of secure payment forms, reduces PCI compliance burden, and supports features like Apple Pay, Google Pay, and stored cards for a seamless checkout experience.
