KonfHub Webhooks: Real-Time Attendee Event Notifications

Webhooks let your systems react to KonfHub events the moment they happen. Instead of polling the KonfHub API for updates, you provide a URL on your server and KonfHub sends an HTTP POST request to that URL whenever a specified event occurs — a new registration, a cancellation, a check-in, and more. This makes it straightforward to keep your CRM, databases, email tools, and spreadsheets in perfect sync with your event’s live data, without building any scheduled jobs or polling mechanisms.

Supported Webhook Events

KonfHub can notify your endpoint for the following event types. You choose which events trigger your webhook when you configure it.

Attendee Registration

Fires when a new attendee successfully completes registration for your event. Includes full attendee details and ticket information.

Attendee Cancellation

Fires when an attendee cancels their registration. Use this to update your CRM, free up reserved resources, or trigger a follow-up workflow.

Check-In

Fires when an attendee is checked in at the venue using the KonfHub Check-in App. Useful for real-time attendance tracking dashboards.

Check-Out

Fires when an attendee checks out of the venue. Helps track session attendance duration and manage capacity in multi-area events.

Lead Generation

Fires when a lead is captured for your event through the Lead Capture App. Use this to immediately push lead data into your sales pipeline.

Configuring a Webhook

Open Your Event Dashboard

Go to Webhooks

Click on Webhooks within the Developers section. You will see the webhook configuration panel.

Enter Your Webhook URL

Paste the URL of the endpoint on your server where KonfHub should send POST requests. Make sure the endpoint is publicly accessible and returns a 200 OK response when it receives a request.

Select the Events to Trigger

Check the boxes next to each event type you want to receive notifications for: Attendee Registration, Attendee Cancellation, Check-In, Check-Out, and/or Lead Generation.

Save and Test

Save your configuration. KonfHub will begin sending POST requests to your URL immediately when the selected events occur. Use a tool like Webhook.site to test and inspect the payload before connecting to your production system.

Your webhook endpoint must be publicly reachable over HTTPS and must respond with an HTTP 200 OK status. Endpoints behind a firewall, on localhost, or returning error codes will not receive webhook deliveries reliably.

Webhook Payload Structure

KonfHub sends webhook notifications as HTTP POST requests with a Content-Type: application/json header. Below is an example payload for an Attendee Registration event:

{
  "event": "attendee.registered",
  "data": {
    "attendee_id": "att_abc123",
    "name": "Jane Doe",
    "email": "jane@example.com",
    "ticket_type": "General Admission",
    "registered_at": "2025-06-15T10:30:00Z"
  }
}

Example: Attendee Cancellation

{
  "event": "attendee.cancelled",
  "data": {
    "attendee_id": "att_abc123",
    "name": "Jane Doe",
    "email": "jane@example.com",
    "ticket_type": "General Admission",
    "cancelled_at": "2025-06-16T08:15:00Z"
  }
}

Example: Check-In

{
  "event": "attendee.checked_in",
  "data": {
    "attendee_id": "att_abc123",
    "name": "Jane Doe",
    "email": "jane@example.com",
    "ticket_type": "General Admission",
    "checked_in_at": "2025-06-20T09:05:00Z",
    "gate": "Main Entrance"
  }
}

Example: Lead Generation

{
  "event": "lead.generated",
  "data": {
    "lead_id": "lead_xyz789",
    "name": "Ravi Kumar",
    "email": "ravi@company.com",
    "phone": "+91-9876543210",
    "captured_by": "exhibitor_booth_3",
    "captured_at": "2025-06-20T11:30:00Z"
  }
}

Always parse the event field first to determine the notification type before processing data. This makes your webhook handler resilient to new event types being added in the future.

Example Use Cases

Webhooks are the foundation for real-time integrations between KonfHub and the rest of your event stack. Here are some common patterns:

Add registrants to your CRM automatically

When a new attendee.registered event arrives, parse the attendee’s name, email, and ticket type, then call your CRM’s API (e.g., HubSpot, Salesforce) to create or update a contact record. This eliminates manual CSV exports and import delays.

Send custom SMS, email, or WhatsApp confirmations

Trigger your own messaging workflow on every attendee.registered event. Route the payload to your SMS provider (e.g., Twilio), transactional email service (e.g., SendGrid), or WhatsApp Business API to send a branded confirmation message outside of KonfHub’s standard communications.

Update a live attendance spreadsheet

Forward attendee.checked_in and attendee.checked_out events to a Google Sheets or Airtable automation to maintain a live attendance log. Pair this with a dashboard for a real-time view of who is on-site.

Push leads directly into your sales pipeline

When a lead.generated event fires, immediately create a deal or opportunity in your CRM and assign it to the appropriate sales representative. This ensures no lead captured at your event booth goes cold.

Trigger Slack or Teams notifications

Send a message to your event operations Slack channel every time a new VIP or speaker registers. Filter on ticket type in your webhook handler and only notify your team for specific registrations.

Retry Behavior and Reliability

KonfHub makes a best-effort delivery of webhook notifications. If your endpoint returns a non-200 status code or is unreachable, KonfHub will retry the request automatically a set number of times with an exponential back-off delay.

To ensure reliable delivery, design your webhook endpoint to be idempotent — processing the same payload more than once should not cause duplicate records or unintended side effects. Use the attendee_id or lead_id fields as idempotency keys.
