## Registering your API keys
To register your API keys:
1. In the BigCommerce platform, click **Apps** and then **Digital River** to open the Digital River Payments, Fraud, Tax & Compliance Management app.
2. Enter your test confidential key in the **Digital River Test Confidential API Key** field. These keys are available on the [Digital River Dashboard](https://dashboard.digitalriver.com/apikeys). The Digital River Production Confidential API Key field can remain empty until you provision the live site.\
**Note**: You are not required to provide the production confidential API key. The **Digital River Production Confidential API Key** field can remain empty until you are ready to go live.
3. Choose one of the following options:
* Select the **Use Digital River Fulfillment** checkbox if you will use Digital River managed fulfillment.
**Important**: Do not select the **Use Production Key** checkbox until testing is complete and you are ready to launch your site.
* **Required**. Select the **Use Digital River Multi-Origin Shipping Option** checkbox and enter the shipping location combination in the **Provide Destination-Origin shipping location combination** field. \
\
The shipping location combination contains the shipping address, a pair of two-letter [Alpha-2 country codes](https://www.iban.com/country-codes) that represent the ship-to country and ship-from country delimited by a right chevron (`>`) such as `FR>FR`. Where France (FR) is the ship-to country and France (FR) is the ship-from country. When entering the shipping location, use the following format: `line1|line2|city|state|postal code|country code`.\
You can use a comma (`,`) to delimit multiple shipping location combinations and a double pipe (`||`)such as if there is no value. For example: \
\
`US>134-135 main street||Minnesota|MN|55343|US,CA>CA,FR>FR,DEFAULT>CN`\
**Note**:
* You must provide the full ship-from address for tax purposes when shipping from Canada or the United States.
* If a ship-to country code is NOT found in the list provided and if the `DEFAULT` key is available, then apply the value from the `DEFAULT` key. In the example above, it would be `CN`.
* If there is NO `DEFAULT` key in the string, then BigCommerce will apply a tax estimate origin address country\_code/locale country\_code.
* If the **Provide Destination-Origin shipping location combination** field is empty, then BigCommerce will apply the tax estimate origin address country\_code/locale country\_code.
