Implementation guide for PayPal Checkout, subscriptions, IPN/webhook handling, and refund workflows for server and client integrations.
This skill provides a practical, implementation-focused guide for integrating PayPal into web applications. It covers client-side Smart Payment Buttons, server-side REST API order creation and capture, IPN/webhook verification and processing, recurring subscription management, payouts, and refund flows. The skill bundles code examples, verification patterns, and testing guidance to reduce common integration errors.
Use this skill when you need to add PayPal as a payment option, implement express checkout, set up subscriptions or recurring billing, process refunds, or handle asynchronous payment notifications. It’s suitable for marketplaces, SaaS subscriptions, and e-commerce checkouts that require robust verification and idempotent processing.
Agents that can read and suggest code changes (Code-capable assistants like Codex, Copilot-style, or Claude Code) and those that can review integration flows will be most useful here.
