Adds support for merchant amount and currency for test mode authorizations
What’s new
When you create a test mode authorization, you can now optionally specify a merchant_amount and merchant_currency.
Impact
You can use merchant_amount and merchant_currency to create valid Authorizations that have currencies that differ from the merchant’s card currency.
With the addition of merchant_, the amount parameter becomes optional. You can specify either amount or merchant_ when you create test mode authorizations.
