Webhook Events

WhatsApp display-name review outcome event

Fired when Meta finishes reviewing a WhatsApp Business display-name change. Forwarded from Meta's phone_number_name_update webhook field on the WhatsApp Business Account. Fires only on a review outcome (name.status APPROVED, DECLINED, or PENDING_REVIEW); a name applied without review reports name_status: AVAILABLE_WITHOUT_REVIEW on the phone node instead and produces no event here. decision REJECTED maps to DECLINED and DEFERRED maps to PENDING_REVIEW, matching the name_status vocabulary returned by GET /v1/whatsapp/number-info. Delivery is at-least-once; dedupe on (account.accountId, name.status, name.requestedName).

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.
