PayPal SDK & API Integration
Guides modern PayPal Orders API and JavaScript SDK v6 integrations with up-to-date eligibility, Braintree, and component patterns.
PayPal Knowledge Patch provides Claude with modern integration patterns and critical post-cutoff updates for the PayPal developer ecosystem. It guides engineers through PayPal Orders API enhancements, JavaScript SDK v6 components, server-side eligibility hydration via @paypal/react-paypal-js, and Braintree-backed PayPal flows. By documenting breaking changes—such as replacing charge_pattern with usage_pattern, updated eligibility fetch helpers, and custom element DOM typings—this skill ensures reliable, compliant payment implementations across web applications.
