PayPal Java SDK

The PayPal Java SDK was developed to simplify the process of accepting a credit card payment via PayPal's service.

Developers can initiate payments, send back funds, check payment details, store credit card details, and also work in live or sandbox environments.

The SDK uses OAuth2 for secure authentication and fetches all responses in JSON.

A sample is included with the download package.

This API is also available for:
PHP
C#/.NET
Ruby
Python
Node.js
