Webhook Events

Message deleted event

Fired when a sender deletes (unsends) a message. Supported on Instagram (incoming unsend) and WhatsApp in both directions: an outgoing message the business deleted (via the Cloud API, or from the WhatsApp Business app on a Coexistence number) and an incoming message the customer deleted. Read message.direction to tell the two apart. The payload retains the pre-delete text and attachments so API consumers can access the original content for moderation or compliance; the Zernio dashboard UI hides it.

Payload

idstring required

event'message.deleted' required

deletedAtstring date-time required

UTC time at which Zernio generated this event (set once when the event payload is built, before delivery is queued). Retries and redeliveries keep the original value, so it reflects the event, not the delivery attempt.

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
