A message the business sent from the WhatsApp Business app on a coexistence number. It is outbound (direction: "out") and wa_id is the recipient. It is not a customer message and never produces message.inbound. This sample is Meta's documented payload, not a capture from a live number.
Event type: message.echo. Fixture payloads are the WhaBuzz Demo tenant's real ids with a fictional customer number; id, tenant_id and created_at in envelopes are illustrative.
