Webhooks v2
Webhooks v2 covers emails, domains, audiences, subscribers, contacts, templates, suppressions and email verifications, with signed requests and automatic retries.

Every request is signed with your webhook secret. To verify one, compute an HMAC-SHA256 of the X-Emailit-Timestamp value, a dot and the raw body, and compare it with the X-Emailit-Signature header. Subscribe to specific event types or to all events. Failed deliveries are retried automatically.
See Webhooks for the current payload format and retry schedule.
