+Feature: Forex
+  Foreign currency exchange, hereafter 'forex', is a feature that allows
+  marketplaces to charge thier buyers in non-USD currencies.
+
+  This provides a better experience for customers who have accounts denominated
+  in other currencies, and reduces chargeback rates for those customers as well.
+
+  Scenario: Debit a card in €
+    Given I have tokenized a card
+    When I make a POST request to the link "cards.debits" with the body:
+      """
+      {
+        "debits": [{
+          "amount": 2000,
+          "currency": "EUR"
+        }]
+      }
+      """
+    Then I should get a 201 Created status code
+    And the response is valid according to the "debits" schema
+    And the fields on this debit match:
+      """
+      {
+        "currency": "EUR"
