# Setting up returns in Global Commerce

The following topics explain how to set up Global Commerce for the Returns API.

### API endpoints

The API consumer interacts with the API through the following endpoints:

* **Production (PROD)**: <https://api.digitalriver.com>
* **Client Test Environment (CTE)**: <https://api-cte-ext.digitalriver.com>

PROD and CTE require your API key and secret (if applicable).

### Setting up your site in Global Commerce

You must enable your site for self-service returns. To enable this feature, contact your Digital River Account Representative.

### Returns API and the Customer Service return functionality

The Returns API has parity with the Customer Service return functionality in Global Commerce. You can expose the Returns API to initiate a return from a non-Digital River-hosted page. Once the return has been accepted, the backend processing runs as expected. The Returns API does not provide additional functionality that is not supported in Global Commerce.

{% hint style="info" %}
**Example**: If a shopper purchases multiple quantities of the same PID (product identifier) or SKU (stock keeping unit) that has a unique identifier such as an IMEI (International Mobile Equipment Identity), Global Commerce does not allow a Customer Service Representative to select which IMEI the customer can return. Therefore, this is not supported in the Returns API, as downstream processing will be affected.
{% endhint %}
