I have created a tool with the type set to "make" Upon call initialization, I aim to retrieve the user's name and email from HubSpot. The webhook is successfully triggered; however, the assistant is unable to process the returned data. The data I sent back in webhook as follows: {   "results": [     {       "toolCallId": "{{2.message.toolCalls[].id}}",       "result": {         "email": "ali@gmail.com",         "firstname": "Ali",         "lastname": "Hassan"       }     }   ] } I would appreciate guidance on ensuring the assistant can correctly interpret and utilize this data. https://cdn.discordapp.com/attachments/1349016155913719931/1349016156370894878/image.png?ex=67d190b3&is=67d03f33&hm=ae49b4b017fdf89f80456fe822b976607fce9b760a91a817986e2a31e71e3078&

Hi Ali! I see you're having trouble with your Vapi assistant processing data from your webhook. Looking at your JSON structure, I've identified a few potential issues: 1. **Tool Call ID Format**: The

toolCallId

value appears to be using a template variable:

{{2.message.toolCalls[].id}}

. This should be replaced with the actual tool call ID from the request. The assistant needs the exact ID to match the response with the original call [(source)](https://docs.vapi.ai/tools/custom-tools). 2. **JSON Structure**: While your overall JSON structure looks correct with the

results

array containing objects with

toolCallId

and

result

fields, ensure you're not transforming arrays to strings during serialization [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1330221332452999321). 3. **Content-Type Header**: Make sure your webhook response has the

Content-Type

header set to

application/json

so Vapi knows how to parse the incoming data [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1330221332452999321). 4. **Testing and Verification**: Try testing your webhook manually using tools like Postman to ensure it works as expected. Check both Vapi and Make.com logs for any errors or misconfigurations [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1336345690393149452). 5. **Dynamic Variables**: If you're using dynamic variables like

userId

, make sure they're correctly implemented in your Vapi SDK configuration [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1339495894801711186).

@User !

Hey @Ali Fawad Hassan , just to clarify, it's getting the tool result but not speaking it correct?

Hello @Mason , Yes. As shown in the attached snippet, I have a make.con scenario triggered by the Assistant. Its a tool call function where I return the first name, last name, and email. However, the Assistant still does not respond correctly.

I hear you boss, can you elaborate on what you mean by responding correctly

As i return the user details using the tool, but once i ask the assistant what my name or email is, the assistant responds with random email and name instead of provided name and email in tool

What LLM are you using?

OpenAi

No worries, can you provide me some call IDs and I'll make sure I follow up with you with a cause and a fix.

I don't believe that's a Vapi call ID. You can find them here: https://dashboard.vapi.ai/calls

6bc0f47b-6f1f-4521-bbf9-f4a8a4b641f0

Can you do me a favor, remove the tool success message, test one more call and provide me that call ID

@Ali Fawad Hassan were u able to fix it? I have same issue

Hey @Ali Fawad Hassan , were you able to remove the tool success message and test?

@Mason i tried this 69e8e597-e6c8-4c48-a558-4d6c44e59d19

🎉🎉 glad to hear it’s fixed my man

Thanks

Hello Ali, what you're experiencing is the default tool start message. If leaving it blank is not working I would recommend putting a "." in the request start message of the tool.

Thanks, it works.

Nice!!! Glad to hear that.
