You can access the caller's identification in your tool handler by extracting it from the

call

object in the

tool-calls

webhook event. Here’s a concise example in Node.js/Express:

js
app.post('/your-tool-endpoint', (req, res) => {
  const { message } = req.body;
  if (message.type === 'tool-calls') {
    const callerId = message.call.customer?.number; // <-- Caller ID here
    // Use callerId as needed in your tool logic
    res.json({ results: [/* your tool results */] });
  }
});

The key is to use

message.call.customer.number

inside your tool handler. [See docs for details](https://docs.vapi.ai/server-url/events) Source: - [Server events](https://docs.vapi.ai/server-url/events)

i already turned this on but it never activates this function but in msg?.assistant?.serverMessages i can aculay see tool has been called https://cdn.discordapp.com/attachments/1437355813629857792/1437360469617807412/Screenshot_11.png?ex=6912f5c0&is=6911a440&hm=db2bb2448dca56038e1b5088b5afa76d28dea528697ecedf9364b25ffa207783&
