Hi Everyone, I'm having issues with Tools sections of the ai agents. I have set up a tool that sends a request n8n to receive some data . the request is sent successfully but the response sent back doesnt show in vapi even though i'm certain a response is sent. the response is sent back in following way : [ { "results": [ { "toolCallId": "", "result": { "exists": true, "first_name": "", "last_name": "", "address": "", "unit_number": "" } } ] } ] I would apperciate some help. Thank you 🙂

Suggestion: Make sure your response includes the correct

toolCallId

from the incoming Vapi request. Here’s an example of the correct response format:

json
{
  "results": [
    {
      "toolCallId": "REPLACE_WITH_ACTUAL_ID",
      "result": {
        "exists": true,
        "first_name": "",
        "last_name": "",
        "address": "",
        "unit_number": ""
      }
    }
  ]
}

Replace

"REPLACE_WITH_ACTUAL_ID"

with the actual

toolCallId

from the request payload. This should allow Vapi to match and display the response correctly. Source: - [Custom Tools Vapi Documentation](https://docs.vapi.ai/tools/custom-tools)

@Vapi Support Bot I include this already in my code as seen in the logs in provided

If you're already including the correct

toolCallId

in your response, double-check that the value is not empty and matches exactly what Vapi sends in the incoming request payload. For example:

json
{
  "results": [
    {
      "toolCallId": "actual_tool_call_id_from_request",
      "result": { "exists": true, "first_name": "", "last_name": "", "address": "", "unit_number": "" }
    }
  ]
}

If the

toolCallId

is empty or mismatched, Vapi will not display the response. Make sure to extract and return the exact value from the incoming request.
