}A thin notification standard webhooks naming the resource to read
At least once, in no particular order. Deduplicate on webhook-id; apply a resource only when its version is
higher than yours; always re-read an availability range. Verify the signature over id.timestamp.body with
each v1, value; during a rotation two are sent. Answer 2xx within 10 seconds. Non-2xx and timeouts are
retried after 1 m, 5 m, 30 m, 2 h, 6 h, then every 12 h (±20 % jitter) for 3 days; then the endpoint becomes
inactive with suspended_reason: failing and your technical contact is mailed. A 410 makes it inactive
at once (gone). Redirects are never followed.
