key should contain the correct fields, including toolCallId
and a non-empty results
array. Since your results
array is empty, that might be why the assistant isn't recognizing the response.
2. **Mismatched `toolCallId`**: Double-check that the toolCallId
in your response matches the one sent in the initial request from VAPI. If they don't match, the assistant won't know which tool call the response corresponds to.
3. **Server-Side Errors**: Review your server logs for any errors that might indicate issues with processing the webhook request. Sometimes, server-side problems can prevent the correct response from being sent.
4. **Content-Type Header**: Make sure that the Content-Type
header of your response is set to application/json
. This helps VAPI parse the incoming data correctly.
5. **Testing**: Use tools like Postman or cURL to manually test your webhook and verify that it behaves as expected.
If you've checked all these and are still having issues, let me know, and we can dig deeper! 😊
