Public Method Callback Function

<!--

    DEMO INFO

    All public methods accept an additional parameter - callback

    function. This function will be called after the specific

    request was made. Unlike generic "data-data-callback"

    which is called once for a request chain (meaning that

    if multiple consequent requests are made only last request

    will return order object) callback functions passed to

    public methods will be called with the order object

    resulted from the call giving you more flexibility around

    integration.

​

    Note: fastspring.builder.checkout() does not accept a

    callback due to its finite nature.

<button onclick="myCallback();">Add to cart and callback</button>

​

<div id="log"></div>

​

<script type="text/javascript">

function myCallback() {

    fastspring.builder.add("phot-io-main-app", function(data){

        document.getElementById("log").innerHTML = "phot-io-main-app was added to cart";

    });

}

</script>
