### Product setup requirements

* [Country of origin](https://docs.digitalriver.com/digital-river-api/product-management/creating-and-updating-skus#country-of-origin)

* [Tax Code](https://docs.digitalriver.com/digital-river-api/product-management/creating-and-updating-skus#tax-code)
* [`skuGroupId`](https://docs.digitalriver.com/digital-river-api/product-management/creating-and-updating-skus#sku-group-identifier)–The `skuGroupId` uniquely identifies a [SKU group](https://www.digitalriver.com/docs/digital-river-api-reference/#tag/SKUs) configured for your Digital River account. A SKU group allows you to define the global markets, trading patterns, and their functionality. For more information, see [Grouping SKUs](https://docs.digitalriver.com/digital-river-api/product-management/setting-up-sku-groups). To configure your SKU groups, contact your Digital River Account Manager.

{% hint style="info" %}
When updating the `skuGroupId`, it is important to update or change the Basic Product details simultaneously. This ensures that the product details are properly synchronized with Digital River when the webhook is triggered.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.digitalriver.com/bigcommerce/1.0-4/introduction/requirements.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
