Joomla Cookie Consent Plugin

Add Conzent to your Joomla site with the official system plugin. Automatic script injection, GTM support, and website key verification.

The Conzent system plugin adds consent management to any Joomla 4 or 5 site. It injects the consent banner script into every frontend page automatically.

  2. In Joomla admin, go to Extensions > Manage > Install
  3. Upload the ZIP file
  4. Go to Extensions > Plugins, search for Conzent
  5. Click the plugin name to open settings
  6. Enter your website key from the Conzent dashboard
  7. Enable the plugin

The consent script is automatically injected into every frontend page.

Features

  • Automatic script injection — the consent script loads in the <head> of every page via onBeforeCompileHead

  • Website key verification — validates your key against the Conzent API when you save plugin settings
  • Joomla 4 & 5 — compatible with both major versions
