How to add an AI chatbot to OpenCart
On OpenCart, a chat widget is installed through catalog/view/theme/<theme>/template/common/footer.twig. Twig templates are cached; a cache refresh is required. Self-hosted, so no plan gate.
Where it goes
catalog/view/theme/<theme>/template/common/footer.twig
Availability: Self-hosted, so no plan gate.
Adding the chatbot to OpenCart
- 1
Open your hosting file manager or connect by FTP.
- 2
Navigate to catalog/view/theme/<your-theme>/template/common/footer.twig.
- 3
Paste the snippet before the closing </body> tag.
- 4
Save, then refresh the theme cache from Dashboard → Extensions → Modifications.
- 5
Twig templates are cached; a cache refresh is required.
The snippet you paste
<script src="https://rubyrep.com/rubyrep.js" data-rubyrep="rr_your_public_key" defer></script>Your own key replaces rr_your_public_key — you get it after training RubyRep on your site.
Worth knowing on OpenCart
Copy the default theme before editing so an upgrade does not overwrite your change.
OCMod and VQMod modifications can rewrite the same file — check for conflicts.
OpenCart questions
- Where does the code go on OpenCart?
- catalog/view/theme/<theme>/template/common/footer.twig. Twig templates are cached; a cache refresh is required.
- Do I need a paid OpenCart plan?
- Self-hosted, so no plan gate.
- Will a OpenCart update remove it?
- Copy the default theme before editing so an upgrade does not overwrite your change.
- Does it slow OpenCart down?
- No measurable effect. The snippet is deferred, so it loads after your page has rendered, and the chat interface itself is only fetched when a visitor opens it.

What is a website chatbot?
The term covers two very different things. Older chatbots follow scripts and break the moment a visitor phrases something unexpectedly. Modern ones retrieve from a business's own content and generate an answer, which handles arbitrary phrasing.

What is AI customer service?
AI customer service means answering customer questions with a language model rather than a person. The useful implementations are grounded in a specific business's own content; the poor ones let a general model improvise, which produces confident answers that are wrong.
