OpenSend docs
domain.created
Domain was created.
When it is emitted
The domain create API emits domain.created after persistence succeeds.
Payload
OpenSend sends this event in the standard webhook envelope:
json
{
"id": "whd_delivery-id_1",
"type": "domain.created",
"created_at": "2026-05-10T00:00:00.000Z",
"data": {}
}Payload includes domain identity fields such as id, name, status, region, DNS records, capabilities, and creation timestamp when available.
Handling guidance
Verify svix-id, svix-timestamp, and svix-signature before processing. Store idempotency by delivery ID or by the domain/email/contact ID in data so retries and replays do not duplicate downstream side effects.
