How it works

Webhook endpoint: POST /api/webhooks/paypal

​
Activation keys

Configure in /admin/plugins → PayPal → Configure. Secret fields stay server-side — never commit them or expose as NEXT_PUBLIC_* unless the key is intentionally public (e.g. Stripe publishable key). * Treat as required before production. Env fallbacks: PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET, PAYPAL_WEBHOOK_ID, PAYPAL_ENVIRONMENT.
