WorldFirst WorldTrade Solution API
The WorldTrade Solution API supports cross-border trade transactions between partners and the WorldFirst platform — e.g. inquiryQuotes (FX quote lookup at /amsin/api/v1/payments/inquiryQuotes), createTradeOrder to submit a trade order, and a WorldFirst-initiated notifyTradeOrderCloseResult asynchronous callback.
