Who should read this:

Any store admin with access to the BigCommerce admin portal.

Global Tracking Script

Place script on every page in header tag (if not already done). Replace the "sid=" parameter value with your store id.

<script type="text/javascript" src="https://cdn.shoppinggives.com/cc-utilities/sgloader.js?sid=XXXXXXXXXX&test-mode=false"></script>

PDP Page (Product Page)

The following code is an example of the product widget integration placed in the base.html file in your Big Commerce store. The bulk of this code is Big Commerce specific code for retrieving and updating of products for the widget. It's main purpose is to feed data into this ShoppingGives function "window.sgProductControllers[0].setSubitem(id, price)" as products are loaded and changed. Replace the "sid=" parameter value on the script with your store id.

The following code is an example of the cart integration placed in the base.html file in your Big Commerce store. It retrieves the cart's content and passes the data in to the cart widget. Replace the "sid=" parameter value on the script with your store id.
