The IFX Standard

A robust message specification that serves the need in the financial services industry to exchange data electronically through a variety of channels in a reliable, consistent manner

We’ve successfully built many services using IFX and will continue to leverage IFX as a service model.

What is IFX?

The IFX standard is a content-rich, well-designed Business Message Specification (BMS), built by financial industry and technology leaders with decades of combined experience. These experts have painstakingly defined, modeled and incorporated real-life use cases to produce relevant and useful business data objects. The result is a consistent framework incorporating best-of-breed design principles and a common object model with carefully defined data definitions.


The IFX standard uses a service-oriented architecture (SOA) framework for interactions between businesses and applications. The framework exposes obvious design patterns, standard abbreviations and common message handling techniques that make it easy to work with in any business or technical setting.  New capabilities can easily be incorporated that are immediately compatible with those previously defined.

Content Domains

The IFX standard covers a broad range of business and technical domains necessary to bank operations.  Content is initially developed by dedicated working groups with interest and subject matter expertise in certain capabilities.  Ongoing oversight is provided by the IFX Architecture Committee.

BMS Access

BMS access is available to all registered users including members, subscribers and non-members.  The same registration provides access to the IFX Community Forum (BBS) where members and non-members share their expertise, asking and answering questions about using the standard in practice.

Implementation Guide

IFX Forum, Inc. provides guidance to members and subscribers in the form of IFX Implementation Guides, a companion Web Services Supplement and a variety of educational and orientation materials. These detailed guides provide high-level orientation to the framework, detailed discussion of key concepts, use-case walk-throughs and working code samples.

Version History

IFX introduced Version 2 of the specification in 2008-2009. Version 2 is the “go-forward” architecture for the IFX standard. We’re committed to maintaining backwards compatibility so that implementations are reliable even as new capabilities are added.
