Why test HubSpot webhooks with HookSense
Real-time WebSocket stream
Events appear the instant HubSpot sends them. No polling, no refresh button.
HMAC-SHA256 over method+uri+body+timestamp (app client secret) verification
Paste your signing secret once — HookSense verifies every HubSpot 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
- 1Get your free webhook URL
Create a free endpoint at hooksense.com. You get a unique URL instantly — no credit card, no config.
- 2Paste it into HubSpot
In the HubSpot dashboard, add the URL as your webhook endpoint and pick the events you want (contact.creation, contact.deletion, etc.).
- 3Trigger an event and watch it arrive
Fire a test event from HubSpot — it lands in HookSense within milliseconds. Inspect headers, body, and signature. Replay when ready.

- v3 signs method + URI + raw body + timestamp — reconstruct the exact string, then HMAC-SHA256 with the client secret and base64-encode
- Reject requests whose X-HubSpot-Request-Timestamp is more than 5 minutes old to block replays
- HubSpot batches multiple events into a single request body (an array) — handle each element
- Use a constant-time comparison when checking the signature to avoid timing attacks
