Installing Apex Chatbot is one copy-paste. Your personal snippet is on your dashboard; it looks like this:
<script async
src="https://apexchatbot.com/widget.js"
data-tenant="YOUR-TENANT-ID"></script>Always copy the snippet from your own dashboard. The data-tenant value is unique to your account.
Open the HTML file of your site (for example index.html). Paste the snippet right before the closing </body> tag, then save and upload.
...your page content...
<script async
src="https://apexchatbot.com/widget.js"
data-tenant="YOUR-TENANT-ID"></script>
</body>Install the free plugin "WPCode" (or any header and footer scripts plugin): Plugins, Add New, search WPCode, Install, Activate.
Go to Code Snippets, Header and Footer. Paste the snippet into the Footer box. Save.
Alternative without a plugin: Appearance, Theme File Editor, footer.php, paste before </body>. Use a child theme so updates do not erase it.
Elementor or Divi: both have a Custom Code area (Elementor: Settings, Custom Code, location body end).
Online Store, Themes, three-dot menu, Edit code. Open layout/theme.liquid. Paste the snippet just before </body>. Save.
Settings, Custom Code, Add Custom Code. Paste the snippet, choose All pages and load it in the Body, end. Apply.
Settings, Developer Tools, Code Injection. Paste the snippet into the Footer field. Save. (Code Injection needs a Business plan or higher.)
Site Settings, Custom Code. Paste the snippet into the Footer Code box. Save and Publish.
Open your website in a private or incognito window. Within a few seconds a gold chat bubble appears in the bottom-right corner. Click it, ask something, and you should get an answer about your business.
