Secure web form to Odoo CRM lead creation with UTM tracking

Web-to-Odoo Lead Funnel (UTM-ready)

Create crm.lead records in Odoo from any webform via a secure webhook. The workflow validates required fields, resolves UTMs by name (source, medium, campaign) and writes standard lead fields in Odoo. Clean, portable, and production-ready.

Key features - ✅ Secure Webhook with Header Auth (x-webhook-token) - ✅ Required fields validation (firstname, lastname, email) - ✅ UTM lookup by name (utm.source, utm.medium, utm.campaign) - ✅ Clean consolidation before create (name, contactname, emailfrom, phone, description, type, UTM IDs) - ✅ Clear HTTP responses: 200 success / 400 bad request

Prerequisites - Odoo with Leads enabled (CRM → Settings → Leads) - Odoo API Key for your user (use it as the password) - n8n Odoo credentials: URL, DB name, Login, API Key - Public URL for the webhook (ngrok/Cloudflare/reverse proxy). Ensure WEBHOOKURL / N8NHOST / N8NPROTOCOL / N8NPORT are consistent - Header Auth secret (e.g., x-webhook-token: <your-secret>)

How it works 1. Ingest – The Webhook receives a POST at /webhook(-test)/lead-webform with Header Auth. 2. Validate – An IF node checks required fields; if missing → respond with 400 Bad Request. 3. UTM lookup – Three Odoo getAll queries fetch IDs by name: - utm.source → sourceid - utm.medium → mediumid - utm.campaign → campaignid If a record is not found, the corresponding ID remains null. 4. Consolidate – Merge + Code nodes produce a single clean object: { name, contactname, emailfrom, phone, description, type: "lead", campaignid, sourceid, mediumid } 5. Create in Odoo – Odoo node (crm.lead → create) writes the lead with standard fields + UTM Many2one IDs. 6. Respond – Success node returns 200 with { status: "ok", leadid }.
