I have a problem: I’m using Coexistence mode, and when a human sends a message through WhatsApp Business, ManyChat receives it and forwards it to my AI Agent as if it were the client’s last message.

I analyzed the reception of 2 JSONs in n8n:

• when a human sends through WhatsApp Business

• when a customer sends a message normally

Both JSONs are identical; there’s no field I can use to identify that it was a human replying. How can I work around this?

I’m sending “Full Contact Data” to n8n via HTTP request, but I haven’t found a way to differentiate the JSON when it’s a human responding.

I’m saying this because my client doesn’t want to stop using WhatsApp Business in favor of ManyChat — he prefers to keep the conversation in the official WhatsApp app. But whenever a human responds via WhatsApp, ManyChat triggers an automation and the AI replies immediately afterward.
