Setup PayPal

Standard PayPal (not Friends & Family) uses create-order plus verify and webhook/IPN settlement.

Routes

Route	Role
POST /api/paypal/create-order	Start PayPal order for a Join Markt order
POST /api/paypal/verify-payment	Client-side verify after return
POST /api/paypal/webhook	Webhook settlement
POST /api/paypal/ipn	Legacy IPN path

Domain helpers live in lib/domains/payments/paypal.ts.

Setup

Enable PayPal in Payment methods and enter client credentials for the store.
Configure return/cancel URLs to the Join Markt checkout invoice.
Point webhooks (and IPN if used) at your deployment origin.
Test a full pay → paid/completed → delivery unlock.

Notes

Create is checkout-lifecycle public + rate limited.
Amount must match the DB order.
For Friends & Family manual flow see Setup PayPal F&F.
Never put PayPal secrets in embed JS.
