HubSpot Webhook Testing — Debug HubSpot Events Instantly

To test HubSpot webhooks, you need a public HTTPS endpoint that HubSpot can POST to. WebhookWhisper gives you one instantly — no CLI, no deployment, no ngrok required. Paste the URL into your HubSpot dashboard, trigger a test event, and inspect the full payload in real time.

Why Test HubSpot Webhooks with WebhookWhisper?

HubSpot webhooks fire on CRM object events — contacts, deals, companies, and tickets. Each subscription targets a specific object type and event.

WebhookWhisper captures every incoming HubSpot event with full headers, body, and timing data — so you can debug integration issues without deploying to a public server.

HubSpot Webhook Events

The following events are commonly sent by HubSpot:

• contact.creation
• contact.propertyChange
• deal.creation
• deal.propertyChange
• company.creation

How to Test HubSpot Webhooks Locally

1. Create your endpoint — Sign up free and get a permanent HTTPS URL in seconds.
2. Add the URL to HubSpot — Paste your WebhookWhisper URL into your HubSpot webhook settings.
3. Enable forwarding (optional) — Add a forwarding rule to relay events to localhost:3000 or any local port.
4. Trigger a test event — Use HubSpot's dashboard or the one-click test sender to fire a contact.creation event.
5. Inspect in real time — See the full payload, headers, and response in your WebhookWhisper dashboard.

HubSpot Webhook Signature Verification

HubSpot signs every webhook request using the X-HubSpot-Signature header. Always verify this signature in production to prevent spoofed requests.

// Node.js — Verify HubSpot webhook signature
const crypto = require('crypto');

function verifyHubSpotSignature(payload, signature, secret) {
  const expected = crypto
    .createHmac('sha256', secret)
    .update(payload)
    .digest('hex');
  return crypto.timingSafeEqual(
    Buffer.from(expected),
    Buffer.from(signature)
  );
}

Common HubSpot Webhook Errors

• 401 Unauthorized — Signature mismatch. Check that you are using the raw request body (not parsed JSON) for HMAC verification.
• Webhook not received — Verify the URL is publicly accessible. WebhookWhisper endpoints are always public — no tunneling needed.
• Timeout errors — HubSpot expects a 2xx response within a few seconds. Respond immediately and process the event asynchronously.
• Duplicate events — HubSpot retries failed webhook notifications up to 10 times over 24 hours. Always use the event ID for idempotency checks.
