To trigger ticket creation when a call ends, set your Vapi assistant's

server.url

to your webhook endpoint. In your server, handle the

end-of-call-report

event like this:

js
app.post('/vapi-webhook', async (req, res) => {
  if (req.body.message?.type === 'end-of-call-report') {
    // Call your ticketing system API here, e.g.:
    // await createTicket(req.body.message);
  }
  res.sendStatus(200);
});

This ensures a ticket is created automatically when a call ends. Adjust the

createTicket

function to match your ticketing system's API requirements. Source: - [Server Events End of Call Report](https://docs.vapi.ai/server-url/events)

The email im refering to with the Support: Re: AW: Integration of REWST Workflow Webhook in Vapi Last updated: 11.09.2025

Create a tool that sends end of call report to the webhook URL and then create an automation on make.com that checks for the contact and mark the customer ticket.

Well, im not using make.com im using REWST.

Hey! To help track down this issue, could you share: \- The call ID \- When exactly this happened (the timestamp) \- What response you expected to get \- What response you actually got instead This would really help us figure out what went wrong!
