After you have configured the domains for your websites you can copy the code found in 
→ 
under «Website» → «Website Integration» and insert it into your template.
Important: For this to process, you will need access to your website's source file. For your chatbot to be available on every subpage, the code must be loaded on every page. Here's an example:
<html>
<head>
<title>Your Website</title>
</head>
<body>
<!-- ... -->
<script type="text/javascript" src="https://chat.aiaibot.com/bootstrap.js" data-aiaibot-key="{{your-key}}" defer></script>
</body>
</html>
