I'm going through the Orbital certification process and my "capture" test cases were rejected because I did not provide the OrderID.
In trying to do so, I discovered that ActiveMerchant does not allow the order_id parameter for capture transactions. By comparison, void transactions do allow it.
ActiveMerchant: 1.60.0
Ruby: 2.3.1
ActiveSupport: 5.0.0.1
Nokogiri: 1.6.8.1
