Conversion Script
Install the conversion script to track user interactions and distinguish genuine engagements from fraudulent activities.
The Conversion Script runs at the moment that matters most — the conversion. It tracks user interactions on your conversion pages so Tapper can distinguish genuine engagements from fraudulent ones.
Installing via a tag manager? Your container must already be live on your website. Both Google Tag Manager and Tealium iQ walk you through that setup when you first create one.
Step 1: Obtain the Script
In your Tapper dashboard, open the desired Protected Website and go to Website monitoring. Copy the Conversion Script, then head to your tag manager (Google Tag Manager or Tealium iQ), or to your website's HTML if you are installing manually.
Copy the conversion script from your Tapper dashboard
Step 2: Add the Script
Create a New Tag
Go to Tags and click New to start a new tag.
Configure the Tag
Choose Custom HTML as the tag type and paste the copied script into the HTML field.
Set Conversion Triggers
Select triggers that activate when a conversion occurs on your website — for example a form submission or a purchase confirmation.
Save the Tag
Name it Tapper - Conversion Script and click Save.
Publish
Click Submit, describe the changes, and click Publish.
Step 3: Send the Conversion Value
Sending the order value turns a conversion into a valued conversion — the signal Tapper Vantage uses to optimise your campaigns toward high-value customers, not just any conversion.
Pass the amount as a plain number (49.99), not a formatted
string. Use a 3-letter currency code (EUR). Multi-currency
stores must always send a currency.
Recommended — Tapper template
Create the order-total variable
Add a Data Layer Variable for your order total
(e.g. ecommerce.value), and — recommended — one each
for currency (ecommerce.currency) and transaction id
(ecommerce.transaction_id). Match your own data layer.
Use the Tapper template
Add a tag from the Tapper - Conversion Script template (GTM Community Template Gallery), or edit your existing one.
Map the fields
Set Order Value to your total variable
(e.g. {{DLV - ecommerce.value}}). Optionally set
Currency and Transaction ID to their variables.
Leave the trigger as your existing purchase event.
Publish
Click Submit, describe the changes, and Publish.
Alternative — Custom HTML tag
If you installed via the copied Custom HTML snippet, replace the hardcoded amount with your order-total variable:
var raw = {{DLV - ecommerce.value}};For currency and order id, use the Tapper template above.
In your browser's Network tab, confirm the conversion request
carries your value (and currency / order_id if set).
Step 4: Verify
Use GTM's Preview mode to confirm the tag fires correctly on conversion pages.
Once verified, your conversion script will accurately monitor and analyze user behavior to detect and block fraudulent activity.
