# Update Multiple Monitors at Once

Instead of updating monitors individually, you can modify all monitors in a group simultaneously. This is useful for managing monitoring behavior across related DNS records or customer domains.

## Bulk Update Endpoint

Use the `PATCH /groups/{slug}/monitors` endpoint to update all monitors in a group:

```
PATCH https://api.dnsradar.dev/groups/production-servers/monitors

frequency: 15
```

This updates the check frequency for ALL monitors in the `production-servers` group to 15 minutes.

## Updatable Properties

You can bulk update these monitor properties:

### Check Frequency

Change how often monitors are checked (in minutes):

```
PATCH https://api.dnsradar.dev/groups/critical-infrastructure/monitors

frequency: 5
```

**Available frequencies**: 5, 10, 15, 30, 60, 120 (minutes)

> ⚠️ **WARNING:** **Plan Limits**: Free plan limited to 60-minute frequency.

### Active Status

Enable or disable all monitors in a group:

```
PATCH https://api.dnsradar.dev/groups/customer-123/monitors

is_active: false
```

Use cases for disabling monitors:
- Temporary maintenance windows
- Customer account suspension
- Testing or debugging
- Service migration

## Update Multiple Properties

Combine frequency and status changes:

```
PATCH https://api.dnsradar.dev/groups/maintenance-mode/monitors

frequency: 120
  is_active: false
```

## API Response

The API returns HTTP 204 No Content on success, indicating all monitors were updated without returning data.

```
HTTP/1.1 204 No Content
```
