Account Balance Retrieval

The getBalance method is used to retrieve the current account balance through the SMS.online API. It automates the process of checking available funds, ensuring expense management and service reliability.

This method is recommended for systems that require regular account status checks and timely top-ups. It helps prevent service disruptions due to insufficient funds.

A successful request returns an object containing information about the current balance, including available funds at the time of the request. This method is particularly useful in automated systems that need real-time balance monitoring.
