Problem Activating workflow because of whatsapp credentials

[Saad_Labri]

I’m self-hosting n8n and trying to connect WhatsApp using the WhatsApp Trigger node. I already added the client ID and secret, but I’m getting the error:
“WhatsApp Trigger: Invalid parameter – Bad request – please check your parameters.”

Also, I’m a bit confused about the webhook setup. Since I’m running n8n locally, I exposed it using ngrok. However, I can’t find the verify token field in the WhatsApp Trigger node when setting up the webhook in the Meta Developer Portal.

If you exposed it using ngrok then webhook should not be localhost it would be like: https://curiously-...wan.ngrok-free.app/rest/oauth2-credential/callback.
try implementing using this guide and try again:
