`GET /api/maintenance-windows`

You can filter by a specific target (e.g. `websiteId`) or by customer/organization.

## Authentication

Requires a valid session.

- Header: `Authorization: Bearer <token>`

## Query Parameters

- `websiteId` (optional)
- `customerId` (optional)
- `organizationId` (optional, defaults to your session organization)
- `activeOnly` (optional): set to `true` to only return active windows
- Target filters (optional, exactly one is typically used when narrowing down):
 - `icmpMonitorId`, `smtpMonitorId`, `sshMonitorId`, `ftpMonitorId`, `imapPopMonitorId`

Note: When `websiteId` is provided, access is enforced for that website.

Note (API token scope): If you use a customer-scoped API token, results are restricted to that customer. Providing a different `customerId` returns `403`.

## Example (cURL)

```bash
BASE_URL="https://uptimeify.io"
TOKEN="<your-api-token>"

curl -X GET \
 "$BASE_URL/api/maintenance-windows?websiteId=101" \
 -H "Authorization: Bearer $TOKEN" \
 -H "Accept: application/json"
```

  "website": {
   "id": 101,
    "url": "https://deinkunde.com"
  }
 }
]
```

Note: The list endpoint only includes the `website` relation (when `websiteId` is set). It does not include nested `customer` objects or monitor relations. A lightweight top-level `customerName` is included for display/filtering.
