{% hint style="info" %}
**Note:** Only contract administrators, owners, and users with permissions to the VDC concerned can create and manage NSGs via API.
{% endhint %}

{% hint style="info" %}
**Prerequisite:** You need an IONOS Cloud account with API credentials configured with the appropriate permissions.
{% endhint %}

{% hint style="info" %}
**Note:** User-created Virtual Machines (VMs) can be Default or Custom NSG members, but you cannot add nodes from the Managed Kubernetes node pools or suspended Cubes.

`PUT(PATCH) /datacenters/{datacenterId}/securitygroups/{securityGroupId}`
