React to ticket changes

Run your own code when a ticket is assigned or checked in.

1. Create an endpoint

In Dashboard → Webhooks, add your server’s HTTPS endpoint and choose the events you need. Save the signing secret as EVENTLAYER_WEBHOOK_SECRET.

2. Verify the request

Inside your request handler, pass the raw body and headers to the SDK.

import { verifyWebhook } from "eventlayer";

const event = await verifyWebhook({
  body: await request.text(),
  headers: request.headers,
  secret: process.env.EVENTLAYER_WEBHOOK_SECRET!,
});

if (event.event_type === "ticket.checked_in") {
  console.log(event.data.id, event.data.checked_in_at);
}

Verification throws for invalid requests. Do not process those payloads.

3. Handle the event

Save the verified event before returning a successful response. Use event.id to deduplicate retries and replays, then process your email, CRM or analytics work.

For delivery history, signing and retries, see the webhook reference.
