n8n Workflows – MC Cars
This folder contains exportable n8n workflow definitions for the MC Cars qualification automation.
Workflows
01 – Qualification Payment Email
Trigger: Postgres NOTIFY on channel lead_qualified (fires when qualify_lead() creates a sales order).
Flow:
- Receives notification with
sales_order_id,customer_id, etc. - Fetches full order + customer data from Postgres.
- Sends HTML email to customer with:
- Booking summary (vehicle, dates, pricing)
- Kaution bank transfer instructions
- Payment link for the rental amount
02 – Mietvertrag PDF Email
Trigger: Same lead_qualified Postgres notification.
Flow:
- Checks if
mietvertrag_template_pathis set insite_settings. - If no template → workflow stops (no error).
- If template exists:
- Fetches customer + sales order data
- Downloads DOCX template from
document-templatesstorage bucket - Fills placeholders using JSZip (in a Code node)
- Converts filled DOCX to PDF via Gotenberg
- Sends PDF as email attachment to customer
Setup Instructions
1. Configure .env
The stack now bootstraps n8n credentials/workflow automatically on every docker compose up.
Required env variables:
POSTGRES_PASSWORDN8N_POSTGRES_CREDENTIAL_IDN8N_POSTGRES_CREDENTIAL_NAMEN8N_SMTP_CREDENTIAL_IDN8N_SMTP_CREDENTIAL_NAMEN8N_SMTP_HOSTN8N_SMTP_USERN8N_SMTP_PASSN8N_PAYPAL_KAUTION_LINKN8N_PAYPAL_MIETE_LINKN8N_PAYMENT_WORKFLOW_ID
2. Mailbox reference (for future incoming-email workflows)
- IMAP host:
heracles.mxrouting.net(port993, SSL/TLS) - POP3 host:
heracles.mxrouting.net(port995, SSL/TLS) - Username:
office@mc-cars.at - Password: same mailbox password as SMTP
3. Import behavior
On startup, n8n runs /opt/mc-cars/bootstrap/bootstrap-n8n.sh which:
- Creates/updates Postgres and SMTP credentials from
.env - Renders
01-qualification-payment-email.jsonplaceholders - Imports the workflow so nodes are always linked to the expected credential IDs
- Activates the payment workflow automatically (
n8n update:workflow --active=true)
4. Upload Mietvertrag template (optional)
- Open Admin panel → Einstellungen tab
- Upload a DOCX file in the "Mietvertrag-Vorlage" section
- The template should contain these placeholders:
| Placeholder | Replaced with |
