Zaraz offers a debug mode to troubleshoot the events and triggers systems. To activate debug mode you need to create a special debug cookie (`zarazDebug`) containing your debug key. You can set this cookie manually or via the `zaraz.debug` helper function available in your console.

1. In the Cloudflare dashboard, go to the **Settings** page.

   [Go to **Settings**](https://dash.cloudflare.com/?to=/:account/tag-management/settings)

2. Copy your **Debug Key**.

3. Open a web browser and access its Developer Tools. For example, to access Developer Tools in Google Chrome, select **View** > **Developer** > **Developer Tools**.

4. Select the **Console** pane and enter the following command to create a debug cookie:

   ```js
   zaraz.debug("YOUR_DEBUG_KEY")
   ```

Zaraz’s debug mode is now enabled. A pop-up window will show up with the debugger information. To exit debug mode, remove the cookie by typing `zaraz.debug()` in the console pane of the browser.
