Frequently Asked Questions about paypal-integration

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add PayPal payments to my e-commerce store?▼

PayPal integration enables secure payment processing through express checkout buttons and REST API calls. Use the PayPal Smart Buttons on your storefront to let customers pay with their PayPal accounts, then handle server-side order creation and capture using the REST API with token-based authentication.

What's the difference between express checkout and subscriptions with PayPal?▼

Express checkout processes one-time transactions with quick client-side payment buttons, while subscriptions create recurring billing plans for automated, ongoing charges. Both use PayPal's APIs but subscriptions require plan setup and customer enrollment.

How do I verify PayPal Instant Payment Notifications?▼

IPN handling securely verifies asynchronous payment confirmations from PayPal by validating webhook messages before processing them. Flask applications can receive and verify IPN data to update order status and trigger refunds or fulfillment automatically.

Can I process refunds with PayPal's REST API?▼

Yes, PayPal refund workflows are handled through REST API calls to issue partial or full refunds after order capture. The Skill covers refund processing logic to reverse transactions and update customer records.

Does PayPal integration support international payments?▼

PayPal's REST API supports international transactions and multi-currency payments across web and mobile storefronts. The Skill handles cross-border payment processing and payout workflows for global e-commerce operations.

What do I need to set up PayPal on my server?▼

Server-side PayPal integration requires Flask as your web framework, the paypalrestsdk library for API calls, and the requests library for HTTP operations. Configure API credentials and set up endpoints to create orders, capture payments, and process IPN notifications.
