Update domain nameservers

Read full description Hide full description

Replace authoritative nameservers for one active domain. Get {id} from GET /api/v2/domains data[].id and read GET /api/v2/domains/{id}/nameservers first; call this endpoint only when actions.canChangeNameservers.allowed is true. HostUp managed nameservers are primary.ns.hostup.se and secondary.ns.hostup.se; using that pair queues a DNS-zone precheck and returns HTTP 202. External nameservers usually complete synchronously with HTTP 200. nsips is optional and aligned by index with nameservers; use it only for in-bailiwick child nameservers such as ns1.example.com when the registry requires glue IPs.

Path Parameters

id string required Example: dom_01hxa3b4c5d6e7f8g9h0j1k2m3
