Now, copy the tracking code.

Change the code (by replacing: **<https://api.goaffpro.com/loader.js>** with **<https://api.goaffpro.com/checkout\\_widget.js>**)

**From tracking script:**

```
<script type="text/javascript" src="https://api.goaffpro.com/loader.js?shop=example "></script>
```

**To popup script:**

```
<script type="text/javascript" src="https://api.goaffpro.com/checkout_widget.js?shop=example"></script>
```

After this, add the popup script in the Advanced Settings > Web Analytics > Affiliate Conversion Tracking > Conversion Tracking Code box in the BigCommerce panel. Finally, click on **Save**.
