To receive an SMS delivery receipt with PHP, you need to install the Slim framework Let's install it now with composer `Vonage will make either a GET or a POST request to your application with the data, depending on how you configured your account`. You'll create a new Slim application and register a handler that responds to both HTTP methods. To handle the incoming request, you'll log the request values to the terminal using error_log. Once your local PHP server is running, you can expose it to the internet by using ngrok to generate a URL. Finally, you'll configure the webhook URL for delivery receipts in the Vonage dashboard and send an SMS to test the functionality.
