Update DNS record

Replace a DNS record using the same validation rules as record creation. Get id from GET /api/v2/dns-zones data[].id and recordId from GET /api/v2/dns-zones/{id} records[].id. Use ALIAS, not CNAME, when the zone root should point at another hostname. NS records here delegate a subdomain only: in zone xyz.se, name: "acme" delegates acme.xyz.se. Changing authoritative nameservers for the domain uses POST /api/v2/domains/{id}/nameservers. The record being edited is excluded from duplicate checks.

Path Parameters

id string required Example: zone_01hxa3b4c5d6e7f8g9h0j1k2m3

Public DNS zone ID. Get it from GET /api/v2/dns-zones `data[].id`. Do not invent this value; use the exact ID returned by the referenced API response.

recordId string required Example: drr_01hxa3b4c5d6e7f8g9h0j1k2m3

Public DNS record ID. Get it from GET /api/v2/dns-zones/{id} `records[].id`. Do not invent this value; use the exact ID returned by the referenced API response.

name string · Example: _dmarc

Record owner name relative to this DNS zone. Use `@` or an empty string for the zone root; use labels such as `www` or `_dmarc`, not the full FQDN `www.example.com`. Responses may return normalized FQDN names. For NS records, send the subdomain label only: in zone `xyz.se`, `name: "acme"` delegates `acme.xyz.se`. This does not change authoritative nameservers for `xyz.se`; use `/api/v2/domains/{id}/nameservers` for that.

value string · Example: v=DMARC1; p=none; rua=mailto:[email protected]

Record target or content. Send TXT/SPF values without surrounding quotes; the server applies DNS-safe quoting and splits long TXT-like values into DNS protocol strings of at most 255 characters. Do not pre-split DKIM/SPF/DMARC values.
