If you want to add one of your chat buttons to your Actinic site, you can do it easily by inserting the button code into the global footer.
First of all, copy the desired chat button - in your LiveAgent navigate to Configuration> Chat> Chat buttons, edit the chosen button and copy the integration code. Now login to your Actinic admin panel and navigate to Site> Properties by Language. Click the modify button so you could place the button code.
Now scroll down and find section 'End </BODY> Block'. Place the button code there.
This is all you had to do, now your site is integrated with the Live Agent button. It will display based on the buttons settings.
