Call the function below to display the electronic cash balance.

    function readBalance() {
        _uz.api.contentWindow.postMessage({
            action: "ecash-api-read-balance"
        }, _uz.api.src);
    };
    

Add post message listener to get returned electronic cash balance.

    window.addEventListener("message", windowEvent);

    windowEvent function (e) {
        if (e.type.match(/(message)/)) try {
            _uz.session = !_uz.session ? e.data.session : _uz.session;
            if (e.data.action && e.data.action.match(/(ecash-api)/)) {

                if (e.data.action && e.data.action.match(/(response)/)) {
                    
                    if (data.action && data.action.match(/(read-balance)/)) {
                        document.querySelector("balance-display").innerHTML = data.balance;
                    };

                };

            };
        } catch (error) {};
    };

Add element to display the electronic cash balance.

    <div id="balance-display"></div>
