How do I create a resource group in Azure using RESTful API in PowerShell?

Question

I want to create an Azure Resource Group using a REST API call, but I can't seem to get the syntax right. Here's what I have:

$validateResourceGroupUri = 'https://management.azure.com/subscriptions/SUBSCRIPTION_ID/resourceGroups/' + $resourceGroupName + '/?api-version=2015-01-01'

try { $trapValidateResponse = Invoke-RestMethod -Method PUT -Headers $armHeaders -Uri $validateResourceGroupUri -Body $deploymentTemplate }
catch { throw $_ }

Where:

$deploymentTemplate = JSON deployment template (obviously)

$resourceGroupName = user-inputted RG name to be created

$armHeaders = @{ 'Authorization' = "Bearer $token"; 'Content-Type' = "Application/json" }

I have a feeling the issue resides in the -Body parameter, but I can't seem to find anything online detailing what exactly the call should consist of. I found THIS where, if you scroll down to "Create a resource group" section, it details some information, but that's unfortunately all I've been able to find. Any thoughts?

What is the error message you're getting? Please share the contents of deployment template as well. — Gaurav Mantri

Are you trying to deploy a template to an existing RG, or trying to create an empty RG? If deploying a template, you should deploy to an existing RG. If creating empty RG, the body should not contain any template but the RG definition like in the link you specified under 'Create a resource group'. — itaysk

You could try to use the following commands to create a new resource group, it works for me.

##get token
$TENANTID="<your tenantid>"
$APPID="<>"
$PASSWORD="<>"
$result=Invoke-RestMethod -Uri https://login.microsoftonline.com/$TENANTID/oauth2/token?api-version=1.0 -Method Post -Body @{"grant_type" = "client_credentials"; "resource" = "https://management.core.windows.net/"; "client_id" = "$APPID"; "client_secret" = "$PASSWORD" }
$token=$result.access_token

##set subscriptionId and resource group name
$subscriptionId="<your subscriptionId >"
$resourcegroupname="<resource group name>"

$Headers=@{
  'authorization'="Bearer $token"
  'host'="management.azure.com"
}
$body='{
    "location": "northeurope",
     "tags": {
        "tagname1": "test-tag"
    }
 }'
Invoke-RestMethod  -Uri "https://management.azure.com/subscriptions/$subscriptionId/resourcegroups/${resourcegroupname}?api-version=2015-01-01"  -Headers $Headers -ContentType "application/json" -Method PUT -Body $body
