n8n is the workflow automation tool people reach for when Zapier gets expensive or when the data should not leave their own server. From the Impreza catalog you can deploy it with its required settings, and there is one setting that decides whether the install is safe: the owner password. This guide covers that, the webhook URL, and how to connect WhatsApp.
What you get
- n8n with 400+ integrations, running as a container on your VPS
- The owner account created at install time, so nobody else can claim the instance
- A public hostname with HTTPS that becomes the webhook URL your integrations call
- An optional Tor mirror, and the choice of an offshore jurisdiction
What you need
A VPS with the Impreza agent. n8n asks for about 512 MB of RAM and 3 GB of disk. Order an offshore VPS and pick n8n in the install picker at checkout, or install it later from My Apps on any server with the agent online.
Install it
Pick n8n in My Apps
Open My Apps, choose n8n from the Marketplace, and select the server.
Set the hostname first
The hostname becomes both the address you sign in at and the base of every webhook URL your workflows expose. Leave it empty for a free n8n-xxxxxx.imprezaapps.com subdomain, or type a domain you own and point its A record at the VPS before installing.
Set the owner password now
Fill in the owner name, email and password. With a password set, the agent completes the owner setup on first boot and you land on a fully configured instance. If you leave it empty, n8n shows the owner setup screen to the first person who loads the URL, and that person becomes the owner.
Install and sign in
Click install. When the card shows running, open the hostname and sign in with the owner credentials you chose. Build your first workflow; the webhook node already shows your public URL.
Optional: connect WhatsApp
Install Evolution API from the same catalog on the same server. It gives you a WhatsApp REST API with webhooks that n8n consumes directly. Keep its global API key private: it is the master key for every number you connect.
An n8n instance without an owner is claimable by anyone who finds the URL. Set the password at install time. If you already installed without one, open the URL now and complete the setup before you share the address anywhere.
With the Impreza MCP connected, ask your assistant to deploy n8n on your server with a domain and an owner password. It calls impreza_deploy_catalog_app with those variables and returns the URL. Adding a Tor mirror later is one more call.
Your recovery plan needs the n8n database, its encryption key and any binary data your workflows store. Keep the key protected: restoring the database without the matching key can leave saved credentials unusable. Check separately any external database or object storage you configured.
Use the app backup guide to check covered paths, storage and job results; also maintain a consistent database backup. Before a server move, pause the workflows and external triggers that could duplicate real actions, verify credential access, and test webhook and callback URLs at the destination. Re-enable production workflows only after validation.
Keep workflow schedules and platform tasks separate
Use n8n’s own scheduling and execution history for workflows built inside n8n. The Impreza task scheduler is a separate app-level facility; it does not import your workflows or inherit their timezone settings. Check which scheduler already owns the job before adding a second trigger.
For deployment problems, start with status, logs and the storage areas available through app inspection. The integrated maintenance CLI is available only for selected catalog apps; do not assume n8n has the same CLI integration as WordPress or Nextcloud.
To connect infrastructure notifications to your automation system, review platform event webhooks. Build and validate the receiver, verify signatures and handle repeated deliveries before enabling actions. These notifications are not n8n workflow-completion events.
