How to resolve “Purchase Conversion Tracking Issue on WooCommerce”

In this doc, we'll walk you through the Purchase tracking tag triggering issue after a successful purchase on the website, and how you can fix it by adding a few lines of code in your store’s theme file.

This issue is relevant if your store uses a custom theme, page builder, checkout customization plugin, or any third-party extension that overrides the default WooCommerce Thank You page behavior.

Why This Happens

The Purchase Event relies on WooCommerce's standard order completion flow and default Thank You page hooks. When these default hooks are bypassed, our plugin's purchase tracking code does not trigger, and purchase data is not reported to the ad platforms.

This typically happens when:

• A custom theme overrides the thankyou.php file
• A checkout customization plugin replaces the default Thank You page template
• A page builder creates a custom order confirmation page
• Custom code redirects users away from the default WooCommerce Thank You page
• WooCommerce hooks are removed or not executed during checkout completion

Pre-requisite:

• Should be using plugin version 5.3.0 or later.

The Solution

This is easy to fix. The simprosys_purchase_action hook accepts either a WooCommerce Order object or simply an Order ID.

So, before adding the script below to your theme file, please check whether you are passing an order object or order ID when a successful purchase happens on the website.

To restore the purchase event, all you need to do is manually trigger the Simprosys purchase action from your custom Thank You page template.

A. Using Order ID

If your template has access to the WooCommerce Order ID directly, use the following implementation:

  if (isset($order_id) && !empty($order_id)) {

      if (has_action('simprosys_purchase_action')) {

          do_action('simprosys_purchase_action', $order_id);

      }

  }

B. Using WooCommerce Order Object

If your template provides a WooCommerce Order Object instead of the Order ID, use the following implementation:

  if ($order instanceof WC_Order) {

      if (has_action('simprosys_purchase_action')) {

          do_action('simprosys_purchase_action', $order);

      }

  }

Note: Use whichever implementation matches to what's already available in your custom template; Avoid adding both solutions to prevent any conflicts.

Typical places to add this code include:

• Your custom thankyou.php template
• Checkout success page template
• Order confirmation page template
• Custom WooCommerce checkout override files
