It is possible to trigger chat invitation programmatically on your website.
For example you would like to display chat invitation to a visitor with special product in his/her shopping cart. Or pop an invitation to live chat to a visitor who is about to leave your site without completing a purchase.
Simply call the following JavaScript function on pages where ZaZaChat button is installed:
function WriteZaZaMessage(zazames,0)
i.e.
<script>
var mes='Hello, the shoes you have in your shopping cart go very nicely with black jeanes we actually have on sale at 20% off today. Please accept this chat invitation to learn more';
WriteZaZaMessage(mes,0);
</script>
