# Block Zone
## Endpoint
`/api/blocked/add`
Obsolete path: `/api/blockZone`
## Method
GET
## Description
Adds a domain name into the Blocked Zones. This creates a new blocked zone entry that will cause the DNS server to block resolution for the specified domain.
## Authentication
Required. A valid session token generated by the `login` or `createToken` call.
## Permissions
Blocked: Modify
## Parameters
| `token` | string | Yes | No | The session token generated by the `login` or the `createToken` call. |
| `domain` | string | Yes | No | The domain name for the zone to be added to the blocked list. |
## Response Fields
| `status` | string | `"ok"` on success. |
## Conditional Logic Notes
- No conditional parameters. Both `token` and `domain` are always required.
- The `domain` parameter must be a valid domain name.
## Edge Cases
- Adding a domain that is already in the Blocked Zones: the API docs do not specify whether this returns an error or is idempotent (silently succeeds). Likely idempotent based on typical Technitium behavior.
- No `node` parameter is documented for this endpoint, so it may not support cluster-aware targeting (unlike the list and export endpoints).
- The response contains only a status field with no confirmation of which domain was added.
