Accept Afterpay payments

To accept Afterpay payments with PayPal, follow these steps in order:

1. Create order: Send a request with intent set as CAPTURE and Afterpay as the payment source to create an order for buyer approval.
2. Redirect buyer: Use the payer-action link from the order response to redirect your buyer to Afterpay's platform for payment approval.
3. Payment completion: Payment is automatically captured immediately upon buyer approval. No additional capture call is required.
4. Track payment status: Monitor payment completion using webhooks for real-time updates or poll the Orders API if webhooks are unavailable.
