# Enable the BI Connector

This section shows you how to enable the BI Connector on an existing cluster.

{% hint style="info" %}
**Note:** This feature is only available for enterprise clusters.
{% endhint %}

## Modify the cluster

The BI Connector is enabled by modifying a cluster attribute with a PATCH request.

* Set `biConnector.enabled` to `true` to enable the BI Connector for this cluster.
* You can disable it at any time by setting this attribute to `false` again.

{% hint style="info" %}
**Note:** Only contract administrators and owners can create and change database clusters. In contrast, the running database cluster can be accessed from all servers in the specified LAN.
{% endhint %}

### Endpoint

Use the following endpoint to enable the BI Connector: `https://api.ionos.com/databases/mongodb/clusters`

{% hint style="info" %}
**Note:** The sample cluster UUID is `498ae72f-411f-11eb-9d07-046c59cc737e`.
{% endhint %}

### Request

```bash
curl --include \
    --request PATCH \
    --user "clientname@ionos.com:Mb2.r5oHf-0t" \
    --header "Content-Type: application/json" \
    --data-binary '{
      "properties": {
        "biConnector": {
          "enabled": true
        }
      }
    }' \
```

### Response

**200 Successful operation**

* The patched resource is returned.
* The `biConnector` property now includes the `host` and `port` attributes needed to connect to the BI Connector. These are read-only attributes and cannot be changed.
* At this point, you have enabled the BI Connector on your database.

{% hint style="info" %}
**Note:** After the BI Connector is enabled, it may take a few minutes until the connector is ready for connections.
