How to Integrate Sleeknote with OpenCart
Emel DalabasmazSleeknote still documents OpenCart. One tracking code, in the theme header.
Source: Sleeknote help: OpenCart, checked 23 August 2026. Paste into header.twig under common, before </head>.
Our 2023 version of this page told you to paste into content_bottom.twig. That does not match the current vendor article. Use header.twig.
Sleeknote is still Sleeknote after the November 2025 founder buyback.
Where is the tracking code?
Dashboard → Tracking Code → Copy. Implement your tracking code.
How do I add it in OpenCart?
- OpenCart admin → Design → Theme Editor.
- Open common → header.twig.
- Paste the Sleeknote snippet before
</head>. - Save. Set the changes live.
The screenshot above is the 2023 capture. If your editor still shows content_bottom.twig in the file list, ignore it for this job. The vendor step is header.twig.
Theme Editor is not on every OpenCart host. Some stores edit files over FTP. Same rule: the snippet belongs in the document head.
