Azure REST Api to create classic deployment model storage account

Question

I'm trying to create Azure storage account kind: Storage (classic) via REST APi.

When I'm sending this request:

PUT https://management.azure.com/subscriptions/{{subscriptionId}}/resourceGroups/{{resourceGroupName}}/providers/Microsoft.Storage/storageAccounts/{{name}}?api-version=2019-04-01

with body:

{
  "sku": {
    "name": "Standard_GRS"
  },
  "kind": "Storage",
  "location": "eastus2"
}

It works perfectly fine, but my created storage is kind: Storage (general purpose v1).

I've tried to send request with Microsoft.ClassicStorage like so:

PUT https://management.azure.com/subscriptions/{{subscriptionId}}/resourceGroups/{{resourceGroupName}}/providers/Microsoft.ClassicStorage/storageAccounts/{{name}}?api-version=2016-11-01

same body as before (and also tried without "kind" parameter), and I get response: 400 Bad Request

{
    "error": {
        "code": "InvalidStorageAccountRequest",
        "message": "The storage account '{{validname}}' request is invalid."
    }
}

Any idea what should be placed in request body? Or is it possible to create Storage(classic) via REST API or by c# code?

Answer 1

Solution (.NET)

Storage Account (classic) doesn't have option to "Export template", but it can be found in another place, as follow:

1. Go to https://portal.azure.com
2. Create a resource (Storage Account)
3. Click on "Choose classic deployment model"
4. Chose tab "Review + create"
5. Click "Download a template for automation"

You should get two JSON files:

• parameter.json (here you can change parameters values):

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "location": {
            "value": "westeurope"
        },
        "storageAccountName": {
            "value": "testtemplate"
        },
        "accountType": {
            "value": "Standard_GRS"
        }
    }
}

• template.json

{
    "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "location": {
            "type": "string"
        },
        "storageAccountName": {
            "type": "string"
        },
        "accountType": {
            "type": "string"
        }
    },
    "variables": {},
    "resources": [
        {
            "name": "[parameters('storageAccountName')]",
            "type": "Microsoft.ClassicStorage/storageAccounts",
            "apiVersion": "2016-11-01",
            "location": "[parameters('location')]",
            "properties": {
                "accountType": "[parameters('accountType')]"
            },
            "dependsOn": []
        }
    ],
    "outputs": {}
}

And now to deploy it, you just need to past it below, with all private credentials (code is copied from Storage Account kind V2 "Export template" tab)

Answer 2

Please try by changing your request body to something like the following:

{
  "properties": {
    "accountType": "Standard-GRS"
  },
  "location": "eastus2"
}

The account kind for classic storage accounts are different than those of new storage accounts. They are Standard-GRS, Standard-LRS, Standard-RAGRS, Standard-ZRS and Premium-LRS.

Answer 3

I have got this kind of issue before and it seems to be because of the name you are giving to your storage account but for me the invalid code was the one bellow:

Code=AccountNameInvalid

It is not a valid storage account name. Storage account name must be between 3 and 24 characters in length and use numbers and lower-case letters only.

you can check it out in the Azure documentation link.
