I’m currently encountering an issue with my voice assistant and webhook integration. Although my webhook is receiving a proper toolCallId and returning a valid JSON response with a message (confirmed via 200 status in logs), the assistant is not speaking the response out loud during the call. Here’s what I’ve verified and implemented so far: The webhook returns a 200 response with the structure: { "results": [ { "toolCallId": "call_XXXXXXXXXXXX", "result": { "message": "This is the text that should be spoken." } } ] } or this: { "results": [ { "toolCallId": "{{ $('Webhook').item.json.body.message.toolCalls[0].id }}", "result": { "spokenResponse": "{{ $json.output }}" } } ] } or "results": [ { "toolCallId": "{{ $('Webhook').item.json.body.message.toolCalls[0].id }}", "result": "{{ $json.output }}" } } ] } i really tried many JSON reponse - it will not work The webhook is working correctly in test mode, and I receive the expected output in the logs. However, during live calls, the assistant does not read the response out loud, even though everything else (like tool calls and branching) works fine. I’ve also tried updating the field name from message to spokenResponse, as mentioned in your Discord and documentation, but it still had no effect. Could you please confirm what exact response structure is required in the webhook for the assistant to speak the result out loud in real-time? Is there any server setting, tool configuration, or mapping required that I may have missed? https://cdn.discordapp.com/attachments/1366874330725879938/1366874331065352316/Bildschirmfoto_2025-04-29_um_12.25.33.png?ex=6812886b&is=681136eb&hm=51ceb194edd8a25ff39c8ed50ed4ea33c15e0336fe9762511cf68ba2aadac260& https://cdn.discordapp.com/attachments/1366874330725879938/1366874331539570768/Bildschirmfoto_2025-04-29_um_12.27.06.png?ex=6812886b&is=681136eb&hm=79cd6608af499c26a93d9521e9d18f8458c23cb01795de5ca23f013b875f108b& https://cdn.discordapp.com/attachments/1366874330725879938/1366874331862536352/Bildschirmfoto_2025-04-29_um_12.27.35.png?ex=6812886c&is=681136ec&hm=5242965eaca5c6db88f616f3dcb06e7d492f2b71c5333c37d82d3ba3e90636a0& https://cdn.discordapp.com/attachments/1366874330725879938/1366874332252475503/Bildschirmfoto_2025-04-29_um_19.23.19.png?ex=6812886c&is=681136ec&hm=a4cfdb2eb3bfd715fdacacc7967aec48cfba6b7d8802ebb206b1839a0f5290e4& https://cdn.discordapp.com/attachments/1366874330725879938/1366874332659454073/Bildschirmfoto_2025-04-29_um_19.26.44.png?ex=6812886c&is=681136ec&hm=e957817d35a943befb0fe96f4c30599cc77fdf6bd350cdb26e0266a5bd10b645&

Hey! To help track down this issue, could you share: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!

thanks a lot Shubham ... here some screenshots. its looks everything fine to me https://cdn.discordapp.com/attachments/1366874330725879938/1367475022947422289/Bildschirmfoto_2025-05-01_um_13.50.24.png?ex=6814b7db&is=6813665b&hm=6794758ae28d1e9582aff06cd27dbe25ce32504a5d45a9fb02cec4d798efe488& https://cdn.discordapp.com/attachments/1366874330725879938/1367475023433957386/Bildschirmfoto_2025-05-01_um_14.15.04.png?ex=6814b7dc&is=6813665c&hm=4e95fa48117263e3e8381114fb7d85f3e441af594d73b15a55e52c76871a783b& https://cdn.discordapp.com/attachments/1366874330725879938/1367475023807512678/Bildschirmfoto_2025-05-01_um_14.15.40.png?ex=6814b7dc&is=6813665c&hm=a22ad1586cf54224e2c0ca341ebdf361c17c01ff632dea954fd4d9246a3a8322& https://cdn.discordapp.com/attachments/1366874330725879938/1367475024272822454/Bildschirmfoto_2025-05-01_um_14.15.49.png?ex=6814b7dc&is=6813665c&hm=80ef59624a2406047c27a289ff1bae09a9f77966801f553daef49475d54cbc7f&

I see in the log that there is a tool_call "terminbuchen" and result is "no result returned". were you expecting a result output here and from the assistant? please let us know what you want the desired result to be if it was to actually work

Thanks a lot Kyle ….. actually i want that vapi just read my webhook response - I thought and saw the tutorials and docus - and they did it like me for reading loud the webhook response from vapi

Thanks. I am investigating right now

thanks bro - i alreday fixed it

Hey @sabri , could you please provide the fix? I'm suffering.

Yes 👍 no Problem - i hope i can help you

Same thing my VAPI is not saying the result to the caller.

Ok 👌

will provide a screenshot of the response from n8n

"results": [ { "toolCallId": "{{ $('Webhook').item.json.body.message.toolCalls[0].id }}", "result": "Deine Antwort hier – z. B. Termin erfolgreich gebucht." } ] }

Take the toolcalld

You need live test

this how it ahould look like? I will change the result https://cdn.discordapp.com/attachments/1366874330725879938/1369394420629246052/Screenshot_2025-05-06_at_10.24.01_PM.png?ex=681bb36f&is=681a61ef&hm=b41bbf1ef71b2f20134078d97bd5208537d6efc38f05fe05e485b5f8fddc3597&

Yes but this

ahaaaa

Try it

👍

Need 200 response

will try it and let u know. Thanks

Tell me - when it works

This is the output but it is not saying it. Also sometime it is passes results by it is owm. For example instead of saying that there are no available slot is say we have some available slots. https://cdn.discordapp.com/attachments/1366874330725879938/1369396689508630709/Screenshot_2025-05-06_at_10.31.58_PM.png?ex=681bb58c&is=681a640c&hm=a681768f17260938ff7744e77184f4a15d13e9d51ac33856804cbc655ee82f86&

Ok

on request start only?

In your picture : is the toolcallid Not the Same ? Did you Check

Sorry I picked wrong picture

And your webhook Must be response webhook

it is response webhook node. Yes, it is POST

Ok

Try costum

Yup

Ok

Make double check - you need the right toolcallID

I'm comparing between the toolcallID for the request and respond and they are all equal.

Ok - what it the http web log ..?

where to find this?

Webhook logs ….

and it is not saying the respond 🙃 https://cdn.discordapp.com/attachments/1366874330725879938/1369406255851896964/Screenshot_2025-05-06_at_11.11.11_PM.png?ex=681bbe75&is=681a6cf5&hm=2aff37af76ef6f0c654e85a59aebae1e97a7d132df1a12f4f0dce71af2a510f9&

Ok 👌- Looks Fine

lol

Your Assistent 😅

oh the webook url you mean

In vapi …. Under your Assistent - i mean is under advance

Yes

ok

👍

Same, should I do any fix in the Client Messages or Server Messages?

Ok …. You sure you have the same Prod URL ?

Started to hate VAPI 😭

Same feeling

Sure no problem. Many many thanks

Belive me …. Its only a small thing

Yeah, I'm 100% sure that it is a small thing.

It’s importent …. It needs live Production

Ok great. Thanks again

Absolut welcome

Many thanks brother, the issue was that I’m using Real-time model

This Model. I changed it to gpt-4o, and it is working. https://cdn.discordapp.com/attachments/1366874330725879938/1369790959314931722/Screenshot_2025-05-08_at_12.39.15_AM.png?ex=681d24be&is=681bd33e&hm=f28960f030bc689c9655915002d579782d0ba4850661159f3d417d8640978a8e&
