Webhook Events

WhatsApp number activated event

Fired when a purchased WhatsApp number becomes active and usable — both the synchronous (Tier 1/2) path and the asynchronous regulated (Tier 3/4) path land here. Lets integrators react without polling GET /v1/phone-numbers.

postWebhookwhatsapp.number.activated

Payload

idstring

event'whatsapp.number.activated'

timestampstring date-time

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.
