The webhook might not fire if:
The call never connects or fails before completion.
The webhook doesn’t return a 2xx response quickly enough (Vapi expects under ~10s).
The webhook URL isn’t registered in Vapi, or the Assistant/project isn’t linked to it.
So, make sure the webhook is registered in Vapi responds with 2xx,and the calls actually complete then the events should trigger automatically.
