I have a problem/bug going on right now with tools not calling webhooks. Every time I test in the chat to assistant area, and I try to call the tool, nothing happens and i just get a blank output. Is this a now glitch right now or is something going wrong on my end. I've tested with both make.com and n8n.

## Check Your Webhook Configuration First, verify your webhook URL and authentication settings:

javascript
// Example of correct tool configuration
{
  "name": "scheduleAppointment",
  "endpoint": "https://hook.us1.make.com/your-webhook-id",
  "method": "POST",
  "headers": {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_KEY"
  }
}

Try testing the webhook manually using Postman or cURL to confirm it's receiving requests properly. Source: - [Discord conversation about webhook configuration](https://discord.com/channels/1211482211119796234/1336345690393149452)

It doesn't even appear to be calling the function at all in the chat when testing the assistant let alone call the webhook.

can you check if your webhook url is saved correctly. I had that blank output as well, it works after I go back to tools, update the url and save again.

Yes I tried updating the webhook url and still had the same problem

Hey, really sorry for your experience. If possible, could you record a loom video describing this error/behavior or inconsistency in the dashboard with the steps to reproduce it? That way, I can share this with my team, and we'll take a look. We'll even try to reproduce the same so we can fix it for you. Also, I'll request you to share your assistant ID.

Hi there, i have attached the images of the tool im trying to call, the section of my prompt which calls it and as you can see in the video we just get a blank response out as if its trying to call the tool but then nothing happens. Is the error happening before the webhook is triggered i.e. the assistant is having issues calling tools inside of Vapi itself. I have tried this across multiple assistants and tools/functions, it appeared to suddenly stop working for all existing ones I had as well. I even created a brand new Vapi account to test this and I'm still getting the issue. The assistant ID from the one in the video is: f2bdbdfd-d171-4c2b-a6f9-5b8bd5e96083 https://cdn.discordapp.com/attachments/1365802284562382958/1366384476753498145/image.png?ex=6810c035&is=680f6eb5&hm=2a844dcf72f3f3ba31bd3e43c280f3e7e6e5e13e573aac1566ef55e4ee07dd7f& https://cdn.discordapp.com/attachments/1365802284562382958/1366384477223256064/image.png?ex=6810c035&is=680f6eb5&hm=bdd3e9b9ddd8f5568585aa9477bb600410f4794de408d465cc5d9406fd3412c6& https://cdn.discordapp.com/attachments/1365802284562382958/1366384477521186877/image.png?ex=6810c035&is=680f6eb5&hm=016492242ab3d34b785ce6cceda25072798693ae362a261ed88414e270f92204& https://cdn.discordapp.com/attachments/1365802284562382958/1366384477869178952/image.png?ex=6810c035&is=680f6eb5&hm=77d70e0bca5e69c9fbadb7a82f50de1cddc7af49ab330d3aedc9c8480d1dc5bb& https://cdn.discordapp.com/attachments/1365802284562382958/1366384478355984437/image.png?ex=6810c035&is=680f6eb5&hm=89ba4d0d75c676b39fa3f11888c89a594a6a15938d2981e8d1a990de909c047d& https://cdn.discordapp.com/attachments/1365802284562382958/1366384478892589056/Recording_2025-04-28_130138.mp4?ex=6810c035&is=680f6eb5&hm=9eaae10108ea7c2bdc36c5d5e046e66d1658224c6fbe22c2006d2cb3647056ff&
