Sent once when no number of the check is pending or dialling and no dial is live (about 2 seconds after the
last reachability.result). For a canceled check it is sent when its last live dial ends, and status
stays canceled.

}Headers
The event type, same as the body's type.
call.ended, call.analyzed, call.status_changed, reachability.result, reachability.completed, campaign.started, campaign.paused, campaign.resumed, campaign.completed, campaign.canceled, campaign.record.updated, call.dispositioned, dialer.contact_updated Delivery id (whd_...), same as the body's id. Stays the same across retries of one delivery: use it to
drop duplicates.
t=<unix seconds>,v1=<hex HMAC-SHA256(secret, t + "." + raw body)>. t is the time of this delivery try.
Verify it before trusting the body (see the Webhooks tag and the event descriptions).

Response
Any 2xx status, within 10 seconds, acknowledges the delivery (the body is ignored). Anything else (other statuses, timeouts, connection errors) is retried: 8 tries in total, 30 seconds after the first failure, then doubling (30 s, 1 min, 2 min, 4 min, 8 min, 16 min, 32 min; about 63 minutes in all). Redirects are not a supported answer.
