Add the Visisto snippet to your PrestaShop theme header. Works on all store pages with no extra module required.

Before you start

A PrestaShop store (version 1.7 or 8.x)
FTP access or file manager access to your PrestaShop theme files
Your Visisto Site Key. Go to Sites → [your site] → Install → Advanced options

Your install snippet

Replace YOUR_SITE_ID with your Site Key from the dashboard under Sites → [your site] → Install → Advanced options. Paste both script blocks before the closing </head> tag.

<script>
  window.__VISISTO__ = {
    site: "YOUR_SITE_ID",
    api: "https://api.visisto.com"
  };
</script>
<script
  src="https://cdn.visisto.com/loader.js"
  data-site="YOUR_SITE_ID"
  data-api="https://api.visisto.com"
  defer
></script>

Step-by-step installation

1
Open your PrestaShop theme folder via FTP or file manager
Navigate to /themes/[your-active-theme]/ in your PrestaShop installation.
2
Open header.tpl in your theme
Find and open header.tpl. This file controls the <head> section on every store page.
3
Locate the closing </head> tag
Search (Ctrl+F) for </head> in the file.
4
Paste the Visisto snippet before </head>
Copy the full snippet above (both script blocks) and paste it immediately before </head>.
5
Save and upload the file
Save header.tpl and upload it back to your server if editing via FTP.
6
Clear the PrestaShop cache
In the PrestaShop admin, go to Advanced Parameters → Performance and click Clear Cache.
Always clear the cache after editing theme files, or changes may not appear.
7
Visit your store to verify
Open your store in a browser and confirm the widget appears on product pages and the homepage.

Tips & notes

Clear the PrestaShop cache after every theme file edit or changes will not show.
If you switch themes, re-add the snippet to the new theme's header.tpl.
Use the Custom HTML Block module to insert code without editing theme files directly.
The snippet works on all PrestaShop page types: category, product, cart, and checkout.
