## POST /api/v2/domains/bulk/dns

**Queue a bulk DNS record operation**

Queue an asynchronous DNS record mutation across multiple domain zones. Use `action: "add"` or `"update"` with `records[]`; use `action: "delete"` with `deleteType`. `domainNames` are domain names, not public `dom_...` IDs. The v2 boundary verifies every submitted domain before queuing; if any domain is not owned by the caller, the entire batch is rejected with Problem Details and `errors[]` pointers. Successful responses return a domain bulk job with a public `dbj_...` ID and `pollUrl: "/api/jobs/{jobId}"`.

### Headers

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

### Request Body

- `action` (string, required) Example: `add`
  Allowed values: add, update
- `domainNames` (array<string>, required) Example: `["example.se","example.nu"]`
- `records` (array<object>, required)
- `records[].type` (string, required) Example: `TXT`
  Allowed values: A, AAAA, CNAME, ALIAS, MX, TXT, SPF, SRV, CAA, NS, TLSA
- `records[].name` (string, required): 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`
- `records[].value` (string, required): 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`
- `records[].ttl` (integer, optional) [min: 60] Example: `3600`
- `records[].priority` (integer, optional) [min: 0, max: 65535] Example: `10`
- `records[].weight` (integer, optional) [min: 0, max: 65535] Example: `0`
- `records[].port` (integer, optional) [min: 1, max: 65535] Example: `443`
