Webhook Events

Conversation started event

Fired once when a new conversation begins between one of your connected accounts and a contact, in either direction. Works across every DM platform (Instagram, Messenger/Facebook, Telegram, WhatsApp, Twitter, Reddit, Bluesky). Naturally deduped — a given conversation only fires this event the very first time it appears.

postWebhookconversation.started

Payload

idstring required

Stable webhook event ID

event'conversation.started' required

startedAtstring date-time required

When the conversation document was created.

timestampstring 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.
