PayPal API
The PayPal API is a set of web services and interfaces provided by PayPal that allows developers to integrate PayPal's payment processing, invoicing, and other financial services into their applications, websites, or mobile apps. It enables secure online transactions, including payments, refunds, subscriptions, and account management, through RESTful APIs and SDKs. This API supports various payment methods like credit cards, PayPal balances, and bank transfers, making it a key tool for e-commerce and digital payment solutions.
Developers should learn and use the PayPal API when building applications that require online payment processing, such as e-commerce platforms, subscription services, donation sites, or marketplace apps, as it provides a trusted and widely recognized payment gateway with robust security features. It is particularly valuable for handling international transactions, recurring billing, and mobile payments, reducing the need to build custom payment infrastructure from scratch. Using the PayPal API can accelerate development, ensure compliance with financial regulations, and enhance user trust through PayPal's brand reputation.
