Use the [az afd origin create](/cli/azure/afd/origin#az-afd-origin-create) command to create a new Azure Front Door origin. The `private-link-location` value must be from the [available regions](../private-link.md#region-availability) and the `private-link-sub-resource-type` value is **blob**.
1. Use the [az network private-endpoint-connection list](/cli/azure/network/private-endpoint-connection#az-network-private-endpoint-connection-list) command to list the private endpoint connections for your storage account. Note the `Resource ID` of the private endpoint connection from the output.

```azurecli-interactive

az network private-endpoint-connection list --name 'mystorage' --resource-group 'myResourceGroup' --type 'Microsoft.Storage/storageAccounts'

```
135

The following are common mistakes when configuring an origin with Azure Private Link enabled:
82
152
83
-
* Adding the origin with Azure Private Link enabled to an existing origin group that contains public origins. Azure Front Door doesn't allow mixing public and private origins in the same origin group.
84
-
* Not using SAS tokens while connecting to storage account that does not allow anonymous access.
