You can check your Twilio account balance at any time via the Twilio Console by clicking Admin in the top right-hand corner, then Account Admin > Account Billing. However, this is a manual and inconvenient process. To automate account balance monitoring, you can use an API call to retrieve your account balance in PHP. You'll need a Twilio account with PHP 8.4 and the Intl extension, as well as Composer installed globally. The code retrieves your account balance using the Twilio Helper Library for PHP, which simplifies interacting with Twilio's APIs. Once set up, you can run the PHP code to retrieve your account balance, which will display the amount in a readable format. Additionally, you can store your Twilio credentials as environment variables and use them in the code to load automatically.
