PayPal configuration

⚠️ PayPal is your live money channel. Changing these keys takes effect immediately for new checkouts.
Saving runs a live auth check against PayPal so you know right away if the keys work.
1) Get your API credentials
developer.paypal.com → Apps & Credentials
→ your app → copy
Client ID +
Secret. Use the
Live tab for real money,
Sandbox tab for testing.
2) Register a webhook (for refunds / disputes sync)
In the same app page →
Webhooks → Add webhook. Webhook URL:
https://preview.sinterpay.com/paypal/webhook
Subscribe to payment capture + refund + dispute events, then copy the generated
Webhook ID into the field above.
Note: leave these blank/unsaved to keep using the deployment's built-in env credentials. Once you save here, the saved values take over.
