PayPal SDK
The PayPal SDK is a software development kit that provides libraries and tools for integrating PayPal's payment processing services into applications. It enables developers to accept payments, manage subscriptions, handle refunds, and access other financial features through PayPal's APIs. The SDK supports multiple programming languages and platforms, simplifying the implementation of secure and compliant payment solutions.
Developers should use the PayPal SDK when building e-commerce websites, mobile apps, or any application requiring online payment processing, as it handles complex payment flows, security, and compliance with financial regulations. It is particularly useful for businesses leveraging PayPal's widespread user base and trust, reducing development time compared to building custom payment integrations from scratch.
