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

**Update DNS record proxying**

Partially update one DNS record's CDN proxy state. Get `id` from `GET /api/v2/domains/{id}/dns` `zone.id` or `GET /api/v2/dns-zones`, and get `recordId` from `records[].id`. This is the DNS-record surface for proxying; callers do not need to list or mutate CDN proxy-rule resources. The endpoint reads the DNS record before changing proxy state, so API-key callers need both `write:cdn` and `read:dns`. The record must be A, AAAA, or CNAME and CDN must be enabled for the zone.

### Related Endpoints

- `PUT /api/v2/dns-zones/{id}/records/{recordId}`: Update DNS record
- `DELETE /api/v2/dns-zones/{id}/records/{recordId}`: Delete DNS record
- `GET /api/v2/dns-zones/{id}/records`: List DNS zone records

### Headers

- `Accept`: application/json
- `Authorization`: Bearer YOUR_API_KEY
- Required API scopes: `write:cdn`, `read: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

- `proxied` (boolean, optional): Set to true to route this DNS record through CDN proxying, or false to keep it DNS-only. Valid only for proxy-capable A, AAAA, and CNAME records. Example: `true`

### Request Examples

#### Enable proxying

```bash
curl -X PATCH "https://cloud.hostup.se/api/v2/dns-zones/zone_01hxa3b4c5d6e7f8g9h0j1k2m3/records/drr_01hxa3b4c5d6e7f8g9h0j1k2m3" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
    "proxied": true
  }'
```

```json
{
  "proxied": true
}
```

#### Disable proxying

```bash
curl -X PATCH "https://cloud.hostup.se/api/v2/dns-zones/zone_01hxa3b4c5d6e7f8g9h0j1k2m3/records/drr_01hxa3b4c5d6e7f8g9h0j1k2m3" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \

    "proxied": false
  }'
```

```json
{
  "proxied": false
}
```

- `ttl` (integer, optional) Example: `3600`
- `priority` (integer,null, optional): Present only for MX and SRV records. `null` means the upstream DNS provider omitted priority for a priority-capable record. Example: `10`

- `proxied` (boolean, optional): Present only on A, AAAA, and CNAME records when the CDN proxy state is known. Omitted for record types that cannot be proxied. Example: `false`
- `proxyReason` (string, optional): Present only when this proxy-capable record has a customer-facing reason that prevents changing the proxy state. Example: `Mail server records cannot be proxied because MX records depend on them.`
- `actions` (object, optional): Compact action gates for state that belongs to this DNS record. Present only when a server-side action gate is relevant to the record.
- `actions.canChangeProxy` (object, required)
- `actions.canChangeProxy.allowed` (boolean, required) Example: `true`
- `actions.canChangeProxy.reason` (string,null, required) Example: `null`
