Website Lead Notification

1. What? — Definition and context

The Website Lead Notification workflow instantly notifies admins on Telegram as soon as a visitor fills out the Odoo contact form. The CRM opportunity is created automatically on the Odoo side, and N8N sends a formatted message with the prospect’s details.

Data flow

Step	Component	Action
1	Odoo form	Visitor submits the contactus form
2	Odoo CRM	Automatically creates an opportunity
3	Automated Action	Detects the new lead (medium=Website)
4	Odoo webhook	Sends data to N8N (internal network)
5	N8N workflow	Formats and routes to Telegram

2. Why? — Stakes and motivations

Problems solved

Problem	Without this workflow	With this workflow
Response time	Lead discovered the next day	Instant notification
Missed leads	Forget to check the CRM	Push to mobile
Lost context	Go back into Odoo to see details	All info inside Telegram

Why use an internal webhook?

Approach	Advantage	Drawback
Internal webhook (Docker)	Secure, no auth needed	Only for Docker services
Polling Odoo API	Simpler to set up	Latency, server load
External webhook	Reachable everywhere	Requires auth + TLS

3. How? — Technical implementation

Architecture

Webhook security

Aspect	Configuration
Internal URL	`http://n8n:5678/webhook/odoo/website-lead`
External access	Blocked by Caddy (403 Forbidden)
Authentication	None (internal Docker traffic)

Caddy configuration:

@internal_webhooks {
    path /webhook/notify/*
    path /webhook/prometheus/*
    path /webhook/odoo/*
}
handle @internal_webhooks {
    respond "Forbidden" 403
}

N8N configuration

Format Lead Node (Code):

const lead = $json.body;

const message = `👤 Contact: ${lead.contact_name || lead.name || 'Not provided'}
🏢 Company: ${lead.partner_name || 'Not provided'}
📧 Email: ${lead.email_from || 'Not provided'}
📱 Phone: ${lead.phone || lead.mobile || 'Not provided'}

💬 Message:
${lead.description ? lead.description.substring(0, 500) : 'No description'}

📋 https://odoo.guigpap.com/odoo/crm/${lead._id}`;

return {
  json: {
    source: "odoo_website_form",
    type: "new_lead",
    severity: "info",
    title: `🌐 New opportunity: ${lead.contact_name || lead.name}`,
    message: message,
    timestamp: new Date().toISOString(),
    hasCallback: false
  }
};

Test commands

# Test the webhook from Odoo
docker exec odoo curl -s -X POST \
  "http://n8n:5678/webhook/odoo/website-lead" \
  -H "Content-Type: application/json" \
  -d '{
    "_id": 999,
    "_model": "crm.lead",
    "name": "Test Lead",
    "contact_name": "Jean Dupont",
    "email_from": "jean@test.com",
    "phone": "+33 6 12 34 56 78",
    "partner_name": "Test Company",
    "description": "Test message"
  }'
# Expected: {"status": "ok"} + Telegram notification

# Check Docker connectivity
docker exec odoo curl -s http://n8n:5678/healthz

4. What if? — Outlook and limits

Current limits

Limit	Impact	Mitigation
Unidirectional webhook	No read-receipt	Link to Odoo in the message
No Telegram reply	Manual return to Odoo	Planned: action buttons
N8N dependency	No notification if N8N is down	N8N container monitoring

Evolution scenarios

If you need to reply from Telegram:

Add inline buttons (Assign, Qualify, Call)
Callback to Odoo to update the lead
Confirmation notification

If lead volume grows:

Filter by lead score
Rotate assignments
Hourly digest instead of instant push

If multi-channel is needed:

Add ntfy as backup
Email notification for VIP leads
Slack integration if a team is involved

Troubleshooting

Problem	Check
No notification	N8N: workflow active? Notification Hub executed?
Webhook timeout	`docker exec odoo curl http://n8n:5678/healthz`
Missing data	Check selected fields in the Odoo webhook
Quiet hours	Notification deferred if 22:00-07:00 (except severity=critical)
