Azure Rest-API Calls from PowerShell

Here is a simple Rest-API call from PowerShell for creating the resource group, using the App Registration:

# Set the Azure AD tenant ID, client ID, and client secret

$tenantId = “<tenant-id>”

$clientId = “<client-id>”

$clientSecret = “<client-secret>”

# Set the Azure subscription ID, resource group name, and location

$subscriptionId = “<subscription-id>”

$resourceGroupName = “<resource-group-name>”

$location = “<location>”

# Obtain a bearer token using Azure AD client credentials flow

$tokenEndpoint = “https://login.microsoftonline.com/$tenantId/oauth2/v2.0/token”

$body = @{

    grant_type    = “client_credentials”

    client_id     = $clientId

    client_secret = $clientSecret

    scope         = “https://management.azure.com/.default”

}

$response = Invoke-RestMethod -Method Post -Uri $tokenEndpoint -Body $body

$accessToken = $response.access_token

# Create the resource group using Azure REST API

$resourceGroupEndpoint = “https://management.azure.com/subscriptions/$subscriptionId/resourcegroups/$resourceGroupName”

$resourceGroupEndpoint = $resourceGroupEndpoint + “?” + “api-version=2021-04-01”

$headers = @{

    Authorization = “Bearer $accessToken”

    “Content-Type” = “application/json”

}

$body = @{

    location = $location

} | ConvertTo-Json

$response = Invoke-RestMethod -Method Put -Uri $resourceGroupEndpoint -Headers $headers -Body $body
