I am not sure if I understand smarthooks correctly or if smartsheet just made a "dumb" implementation.
I can create a hook but verification failosm OF COURSE. It expected the url to send something special back (Smartsheet-Hook-Response: <sendID>).
Unless this is not a generall webhook standard that bodes get echoes back, smarthooks would be useless as I cant just use any URL which supports callbacks.
What am I missing here ? ( I am trying to integrate with Zapier webhooks)
