# Create an Authorize.net Payment Gateway

When setting up Blackthorn Payments, we suggest you connect your Payment Gateway in test mode so that you can create test Transactions, Payment Methods, and Customers.

          **Multiple Currencies**

          

If you need to support multiple currencies through your Authorize.net gateway you must create a unique gateway for each currency. This is an Authorize.net limitation. To ensure your Transaction record currency matches your Payment Gateway currency, [learn more](https://docs.blackthorn.io/v1/docs/custom-settings) about Transaction validation rules.
