 Configuring the minimum TLS version requires api-version 2022-01-01-preview or later of the Azure Event Hubs resource provider.
 
+## Check the minimum required TLS version for a namespace
+
+To check the minimum required TLS version for your Event Hubs namespace, you can query the Azure Resource Manager API. You will need a Bearer token to query against the API, which you can retrieve using [ARMClient](https://github.com/projectkudu/ARMClient) by executing the following commands.
+
+```powershell
+.\ARMClient.exe login
+.\ARMClient.exe token <your-subscription-id>
+```
+
+Once you have your bearer token, you can use the script below in combination with something like [Rest Client](https://marketplace.visualstudio.com/items?itemName=humao.rest-client) to query the API.
+
+```http
+@token = Bearer <Token received from ARMClient>
+@subscription = <your-subscription-id>
+@resourceGroup = <your-resource-group-name>
+@namespaceName = <your-namespace-name>
+
+###
+GET https://management.azure.com/subscriptions/{{subscription}}/resourceGroups/{{resourceGroup}}/providers/Microsoft.EventHub/namespaces/{{namespaceName}}?api-version=2022-01-01-preview
+content-type: application/json
+Authorization: {{token}}
+```
+
+The response should look something like the below, with the minimumTlsVersion set under the properties.
+
+```json
+{
+  "sku": {
+    "name": "Premium",
+    "tier": "Premium",
+    "capacity": 1
+  },
+  "id": "/subscriptions/<your-subscription-id>/resourceGroups/<your-resource-group-name>/providers/Microsoft.EventHub/namespaces/<your-namespace-name>",
+  "name": "<your-namespace-name>",
+  "type": "Microsoft.EventHub/Namespaces",
+  "location": "West Europe",
+  "properties": {
+    "minimumTlsVersion": "1.2",
+    "publicNetworkAccess": "Enabled",
+    "disableLocalAuth": false,
+    "zoneRedundant": true,
+    "isAutoInflateEnabled": false,
+    "maximumThroughputUnits": 0,
+    "kafkaEnabled": true,
+    "provisioningState": "Succeeded",
+    "status": "Active"
+  }
+}

 ## Test the minimum TLS version from a client
 
 To test that the minimum required TLS version for an Event Hubs namespace forbids calls made with an older version, you can configure a client to use an older version of TLS. For more information about configuring a client to use a specific version of TLS, see [Configure Transport Layer Security (TLS) for a client application](transport-layer-security-configure-client-version.md).
