Seamless integration powered by EventHex
Automation Without Limits
Webhooks for developers. Zapier for everyone else. Both in one integration.
Real-Time Webhooks
Receive HTTP POST callbacks on 15+ event types — registration, payment, check-in, session attendance, feedback submission, and more.
Zapier Integration
Connect EventHex to 5,000+ apps through Zapier. No code required. Set up Zaps that trigger on any EventHex event type.
Webhook Signature Verification
Every webhook payload is signed with HMAC-SHA256. Verify signatures to ensure payloads are authentic and untampered.
Automatic Retries
Failed webhook deliveries are retried automatically with exponential backoff. View retry history and manually re-trigger failed deliveries.
Full REST API
Beyond webhooks, EventHex provides a complete REST API for reading and writing event data. Build custom integrations at any depth.
Test Mode
Send test webhook payloads to your endpoint before going live. Validate your integration logic without creating real events.
How It Works
Create Endpoint
Register a webhook URL in EventHex settings. Choose which event types trigger deliveries to this endpoint.
→Verify Signature
Validate the HMAC-SHA256 signature on each incoming payload to confirm authenticity.
→Handle Payload
Parse the JSON payload and execute your custom logic — update a CRM, send a notification, create a record.
→Or Use Zapier
Prefer no-code? Connect EventHex to Zapier and build automations with a visual drag-and-drop editor.

Connect EventHex to Any Tool in Your Stack
Webhooks, Zapier, or the REST API — choose how you connect. Build event-driven workflows that scale with your events.
What event types can trigger webhooks?
EventHex supports 15+ event types including registration.created, payment.completed, checkin.scanned, session.attended, feedback.submitted, ticket.refunded, and more. Each endpoint can subscribe to specific event types.
Is there a Zapier app for EventHex?
Yes. EventHex has a dedicated Zapier app with triggers for all major event types and actions for creating registrations, updating attendee data, and more.
What format are webhook payloads?
All webhook payloads are JSON. Each includes a timestamp, event type, event ID, and the full object data. Schema documentation is available in the EventHex developer docs.
Are there rate limits on webhooks?
EventHex sends webhooks as events occur with no artificial throttling. If your endpoint is slow to respond, deliveries are queued and retried with exponential backoff.
How are webhooks secured?
Every payload is signed with HMAC-SHA256 using a secret key unique to your account. You should verify the signature on every incoming request to ensure authenticity.
