Gigya allows you to specify a callback function when placing a Share Bar on your site. This callback function can be used to publish custom Events to BlueConic when a visitor uses the share bar. The following example shows how:

<script type="text/javascript">
    var handleEvent = function(eventObj) {
        if (eventObj.eventName && window.blueConicClient) {
           if (eventObj.eventName == 'sendDone') {
            window.blueConicClient.event.publish('gigya-' + eventObj.providers);
        }
           if (eventObj.eventName == 'shareButtonClicked' && eventObj.shareItem) {
            window.blueConicClient.event.publish('gigya-' + eventObj.shareItem.provider);
        }
        }
    };
    var act = new gigya.socialize.UserAction();

    var showShareBarUI_params=
    {
        containerID: 'sharebarDiv',
        shareButtons: 'facebook-like,facebook,twitter-tweet,googleplus-share,share',
        userAction: act,
        hideGigyaLink:true
        ,lang:'nl',
        onSendDone: handleEvent,
        onShareButtonClicked : handleEvent
    }
    gigya.socialize.showShareBarUI(showShareBarUI_params);
</script>

This will publish an event to BlueConic using the following syntax: “gigya-<provider code>”.

After the script has been added to your website you can configure listeners to subscribe to these events. This article describes how custom events in BlueConic work.
