Integrating with OpenCart - Tapfiliate Help Center

November 9, 2026

Integrating Tapfiliate with OpenCart lets you track conversions and commissions based on order amounts for your online store.

To get started: 1. Log in to your OpenCart admin panel, navigate to Design > Theme Editor > Common > header.twig. Just before the closing </head> tag, insert the provided code snippet below and click the “Save” button.

<script src="https://script.tapfiliate.com/tapfiliate.js" type="text/javascript" async></script>
<script type="text/javascript">
    (function(t,a,p){t.TapfiliateObject=a;t[a]=t[a]||function(){
    (t[a].q=t[a].q||[]).push(arguments)}})(window,'tap');

    tap('create', 'YOUR ACCOUNT ID', { integration: "opencart" });
    tap('detect');
</script>

Be sure to replace ‘YOUR ACCOUNT ID’ with your actual account ID. 2. Next, proceed to Design > Theme Editor > Common > success.twig. Place the following code after #{{ header }}.

<script src="https://script.tapfiliate.com/tapfiliate.js" type="text/javascript" async></script>
{% if orderDetails %}
<script type="text/javascript">
    (function(t,a,p){t.TapfiliateObject=a;t[a]=t[a]||function(){
    (t[a].q=t[a].q||[]).push(arguments)}})(window,'tap');

    tap('create', 'YOUR_ACCOUNT_ID_HERE', { integration: "opencart" });
    tap('conversion', "#{{ orderDetails.id }}", #{{ orderDetails.amount }});
</script>
{% endif %}

Make sure to replace ‘YOUR ACCOUNT ID’ with your actual account id. 3. Lastly, on your server, locate catalog/controller/checkout/success.php. Insert the provided code snippet right after $this->load->language('checkout/success');

    if (isset($this->session->data['order_id'])) {
        $this->load->model('checkout/order');
        $order_id = $this->session->data['order_id'];

        $order_data = $this->model_checkout_order->getOrder($order_id);
        $sub_total = '0';
        foreach ($this->model_checkout_order->getOrderTotals($order_id) as $total) {
            if ($total['code'] == 'sub_total') {
                $sub_total = $total['value'];
            }
        }

        $orderDetails = array(
            "id" => $order_data['order_id'],
            "amount" => $sub_total,
            "currency" => $order_data['currency_code'],
        );

        $data['orderDetails'] = $orderDetails;
    }

4. Save your changes, and you’re all set! Please remember to conduct a conversion test before launching your program. This step will help you confirm that tracking has been correctly established. You can create a test conversion by following the steps described here.
