Unusual Ghost Messages Appearing in n8n WhatsApp Workflow

Questions
1

Whenever I activate my n8n workflow, I keep receiving unexpected responses from WhatsApp — even when no user is sending any messages.

It behaves as if a user is actively chatting, and the webhook keeps getting triggered repeatedly. The messages being saved into Postgres include entries like “hi”, “1”, and “j”, even though none of these were actually sent by any user.

At the moment, I’m not sure what is causing these random incoming messages, and I can’t identify the source of the triggers.

Since this messages are not duplicates it’s possible that queued or test events from WhatsApp or your API provider are being replayed.

This can happen if the webhook URL was changed or re-registered, causing WhatsApp to resend verification or test messages.

What does your Trigger looks when is being hit with a request?

In the header should be some info’s about id , url etc…
