Hi, I created a custom tool called collect_lead_info tool so I can get the lead information from the call and send it to Google sheet using a webhook url created on Google maps script. See the link below https://script.google.com/macros/s/AKfycbzEYfWvGprsmu73mLUek0WZQ9GUh4L6tiEgaMLbiUuwlLqQfJfUuTIu9rFMd6KUH90o/exec Right now, the agent is calling the tools to collect the information but it's not sending it through the webhook url correctly. See the error message from the screenshot below Please rectify it for me https://cdn.discordapp.com/attachments/1415202198555590847/1415202199117631608/Screenshot_2025-09-10-05-55-11-55_4d38fce200f96aeac5e860e739312e76.jpg?ex=68c25941&is=68c107c1&hm=babd84bef62d44fc17045b38aaf3bff6c0c0359cfed5aced9b184d7f7998789d& https://cdn.discordapp.com/attachments/1415202198555590847/1415202199587520585/Screenshot_2025-09-10-05-27-28-46_4d38fce200f96aeac5e860e739312e76.jpg?ex=68c25941&is=68c107c1&hm=89f6c55ea3ccdf69552d9b21fb10828355abaa7f050ec4e1bbd00f2053e27435&

Thanks for sharing the details and screenshots. To help diagnose the issue, could you please confirm if your webhook URL requires any authentication (such as a secret token or custom headers), or is it publicly accessible without authentication? This will help determine if the connection problem is due to missing or incorrect authentication settings in your Vapi tool configuration. Once you provide this info, I can guide you on the next steps to resolve the webhook connection issue.

@Vapi Support Bot there is no authentication needed

Oftentimes when this error occurs (no response returned from tool) it typically means the data is actually being sent but is in the incorrect format/structure. You’ll need to adjust it to match the expected format. You can check out the documentation and snippet below for the correct details. Hope this helps! Documentation Link: Tool Call Response Format:

{
  "results": [
    {
      "toolCallId": "X",
      "result": "Y"
    }
  ]
}
