      description: 'Currently FX rates can be retrieved through the WorldLink FX Rate Inquiry endpoint, Book FX through WorldLink FX Book API endpoint and Cancel FX via the WorldLink FX Cancel API endpoint. The FX contract Status endpoint verifies the FX status if the the response of FX Book is not received or non-conclusive. The FX contract might be in various statuses - such as Booked, Cancelled, or Not found because the Deal may not even exist. The FX Contract Status will inquire about the whereabouts of an FX deal.
