Hi @ahmed_fadul

make sure your workflow is published and active before registering the production webhook URL with Facebook, that’s the most common cause of this error.

n8n Cloud: Hit Publish in the top right of your workflow, then retry the URL validation in Facebook.

Self-hosted: Same! publish the workflow first. Also make sure your WEBHOOK_URL environment variable is set to your public domain with HTTPS, otherwise the production URL n8n shows will be wrong and Facebook won’t be able to reach it.

Let me know if this works
