## PUT /api/v2/dns-zones/{id}/records/{recordId}

**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.

### Related Endpoints

- `DELETE /api/v2/dns-zones/{id}/records/{recordId}`: Delete DNS record
- `POST /api/v2/dns-zones/{id}/records`: Create DNS record
- `GET /api/v2/dns-zones/{id}`: Get DNS zone and records

### Headers

- `Accept`: application/json
- `Authorization`: Bearer YOUR_API_KEY
- Required API scope: `write:dns`
- `Content-Type`: application/json

### Parameters

- `id` (path, string, required): 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. Example: `zone_01hxa3b4c5d6e7f8g9h0j1k2m3`
- `recordId` (path, string, required): 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. Example: `drr_01hxa3b4c5d6e7f8g9h0j1k2m3`

### Request Body

- `type` (string, optional) Example: `TXT`
  Allowed values: A, AAAA, CNAME, ALIAS, MX, TXT, SPF, SRV, CAA, NS, TLSA
- `name` (string, optional): 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. Example: `_dmarc`
- `value` (string, optional): 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. Example: `v=DMARC1; p=none; rua=mailto:dmarc@example.com`
- `ttl` (integer, optional) [min: 60] Example: `3600`
- `priority` (integer, optional) [min: 0, max: 65535] Example: `10`
- `weight` (integer, optional) [min: 0, max: 65535] Example: `0`
- `port` (integer, optional) [min: 1, max: 65535] Example: `443`
