message.send.failed

Opt-in. A POST /messages operation of this integration ended failed — including failures before Meta accepted the message, which produce no message.status.updated (a free-form text outside the 24h window, a blocked contact, a send guard rejection). Sent only to the integration that queued the send. Since 1.46.
