Why test PayPal webhooks with HookSense

Real-time WebSocket stream

Events appear the instant PayPal sends them. No polling, no refresh button.

SHA256withRSA (cert-based, not shared-secret HMAC) verification

Paste your signing secret once — HookSense verifies every PayPal request automatically.

One-click replay

Send any captured webhook back to your local server or production — rerun your handler without triggering new events.

CLI forwarding, no ngrok

Forward directly to localhost:3000 with npx hooksense listen.

Quick start — 3 steps

  1. 1
    Get your free webhook URL

    Create a free endpoint at hooksense.com. You get a unique URL instantly — no credit card, no config.

  2. 2
    Paste it into PayPal

    In the PayPal dashboard, add the URL as your webhook endpoint and pick the events you want (PAYMENT.CAPTURE.COMPLETED, PAYMENT.CAPTURE.REFUNDED, etc.).

  3. 3
    Trigger an event and watch it arrive

    Fire a test event from PayPal — it lands in HookSense within milliseconds. Inspect headers, body, and signature. Replay when ready.

Forward to localhost

npx hooksense listen -p 3000 --path /api/integrations/paypal

Testing tips specific to PayPal

  • PayPal uses RSA cert verification, not a shared HMAC secret — verify against the cert at Paypal-Cert-Url or call POST /v1/notifications/verify-webhook-signature
  • HookSense captures all five Paypal-Transmission-* headers so you can debug verification failures
  • Use the PayPal Webhooks simulator to fire test events without a real transaction
  • Sandbox and live events hit the same endpoint — use HookSense search to tell them apart
