## POST /api/v2/domains/{id}/dnssec-auto

**Enable or disable automatic DNSSEC**

Toggle automatic DNSSEC enrollment. Send `action: "include"` to re-enroll the domain or `action: "exclude"` to opt the domain out; unknown fields are rejected so clients do not assume force or refresh options exist. `include` does not bypass nameserver propagation or the 72-hour cooldown after nameserver changes: the returned state may still be `pending` or `blocked` with `blockedUntil`, `blockReason`, and `nameserversChangedAt`. Use this automatic flow for domains delegated to HostUp-managed nameservers such as `primary.ns.hostup.se` and `secondary.ns.hostup.se`; use manual `POST /api/v2/domains/{id}/dnssec` only when an external DNS provider or registrar workflow requires caller-supplied DS/KEY data.
