CitiConnect FX (Real-Time FX) API
The CitiConnect FX API provides real-time foreign-exchange information and execution for corporate treasury clients, supporting FX rate requests and the booking of FX contracts directly from ERP and TMS systems. It is one of the most-used CitiConnect data services, enabling treasurers to embed live rates and deal booking into automated workflows across the TTS footprint. Access uses OAuth 2.0 with mutual TLS; documentation and sandbox are provided to onboarded corporate clients, with no public downloadable specification.
