It’s been over 3 days since I opened a support request through the Cloud dashboard and I haven’t received a reply yet. I’m trying to complete a workflow that connects my OpenAI Chat Model1 node to Respond to Webhook1 for instant reply testing.
Everything is set up on my megabucks4u.app.n8n.cloud instance, but the webhook returns a timeout or no response. Could someone please check my ticket status or help me get this workflow operational?
Describe the problem/error/question
What is the error message (if any)?

Hey! Welcome to the community.
Could you share your workflow (or part where is the issue) here?

Thanks for replying!
Here’s the part of the workflow that’s giving me trouble. It’s supposed to send instant replies from my OpenAI Chat Model1 node back to the Respond to Webhook1 node for use in my front-end ChatWidget (hosted on my TPFN project).
The workflow runs successfully inside the editor, but the webhook never returns a visible response to the front end.
Here’s the JSON for the relevant nodes:
{
"nodes": [
{
"parameters": {
"path": "tpfn-intake",
"options": {}
},
"name": "Webhook",
"type": "n8n-nodes-base.webhook",
"typeVersion": 1,
"position": [200, 300]
},
{
"parameters": {
"model": "gpt-4-turbo",
"mode": "chat",
"messages": [
{
"role": "system",
"content": "You are Cupcake, the TPFN onboarding assistant."
},
{
"role": "user",
"content": "{{$json[\"message\"]}}"
}
]
},

},

"responseMode": "lastNode",

"responseBody": "={{ { \"reply\": $node[\"OpenAI Chat Model1\"].json[\"message\"][\"content\"] || \"No reply returned.\" } }}"
},
"name": "Respond to Webhook1",
"type": "n8n-nodes-base.respondToWebhook",
"typeVersion": 1,
"position": [800, 300]
}
],
"connections": {
"Webhook": {
"main": [
[
{
"node": "OpenAI Chat Model1",
"type": "main",
"index": 0
}
]
]
},
"OpenAI Chat Model1": {
"main": [
[
{
"node": "Respond to Webhook1",
"type": "main",
"index": 0
}
]
]
}
}
}
Also planning to extend the workflow to drive traffic into my Unlock The System™ funnel via a new /lead-capture webhook that validates emails, checks IPs, scores leads, logs to Sheets, and sends Gmail + Slack notifications.
Current blocker: Respond to Webhook1 not returning message text for front-end ChatWidget testing.
Set the Webhook node’s Respond parameter to Using ‘Respond to Webhook’ Node.
Ensure the Respond to Webhook node is configured to return the data in the format your front end expects.
Use the Production URL and activate the workflow for live use.
I received this back from my front end chatwidget→ {“code”:404,“message”:“The requested webhook \“POST tpfn-intake\” is not registered.”,“hint”:“The workflow must be active for a production URL to run successfully. You can activate the workflow using the toggle in the top-right of the editor. Note that unlike test URL calls, production URL calls aren’t shown on the canvas (only in the executions list)”}
Ohh…
Then simply activate the workflow?
Open your workflow, in the right side , top near … settings dots you have to toggle “activate”.
Now I’m receiving this {
"code": 404,
"message": "The requested webhook \"POST tpfn-intake\" is not registered.",
"hint": "The workflow must be active for a production URL to run successfully. You can activate the workflow using the toggle in the top-right of the editor. Note that unlike test URL calls, production URL calls aren't shown on the canvas (only in the executions list)"
