n8n is writing duplicate leads into your CRM
The same person shows up two or three times in your CRM. It looks like a CRM problem, but it usually starts upstream in the workflow.
Why it happens
There's no 'Remove Duplicates' step (or dedupe by a unique key), so retries, double submits and re-runs each write a fresh record.
How to fix it
Add a 'Remove Duplicates' step, or dedupe by a unique key like email, before the node that writes the lead.
How to verify
Submit the same lead twice and confirm only one record is created downstream.
