Click the Twilio number that is currently connected to Missive.
Find Messaging configuration, then A message comes in.
Replace the Missive webhook with the Incoming SMS webhook above. The method must be HTTP POST.
Save the number. New texts will arrive here. Older Missive messages stay in Missive.
The status callback is attached automatically to messages this app sends. Do not put that URL in the “A message comes in” box. Twilio can only reach this PC after PUBLIC_BASE_URL is a public https address and the server has been restarted.
