Website to CRM Automation - n8n and Twenty CRM Pilot

Internal automation pilot We replaced an unverified email handoff on the Marsentech website with a confirmed, deduplicated CRM receipt. This case is internal implementation work dated 17 September 2026. Workflow: same-origin website form → Vercel endpoint → private n8n workflow → Twenty CRM task. The implementation validates submitted fields, enforces the production origin, uses a request reference for deduplication, and returns an acknowledgement without exposing private CRM identifiers. A person still reviews the enquiry and decides how to follow up. Documented acceptance test: one synthetic enquiry plus an identical replay produced exactly one CRM task. An unapproved-origin request returned HTTP 403. These are limited implementation checks, not measured revenue, conversion or time-saving results. Read the dated case and limitations: https://www.twine.net/signin Relevant client services: n8n workflow automation, CRM integrations, API connections and lead-routing systems. Client implementations are scoped around access, privacy, reliability, acceptance checks and handover. The lead image shows the public case-study page.
