UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This workflow has 7 nodes and runs when an HTTP POST request hits its webhook URL. Along the way it connects Polydoc (community).
How it runs
Trigger: When an HTTP POST request hits its webhook URL.
- Valid order? (If): checks a condition and branches into true / false
- Build invoice (Code): runs custom JavaScript code
- Reject (422) (Respond to Webhook): sends the response back to the webhook caller
- Render invoice PDF (Poly Doc): uses Poly Doc
- Email invoice (Send Email): sends an email over SMTP
- Return PDF (Respond to Webhook): sends the response back to the webhook caller
Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-polydoc is verified or supports 3.0 (used in Render invoice PDF).
