Welcome to FDC3 2.2 (pre-draft)

The mission of the Financial Desktop Connectivity and Collaboration Consortium (FDC3) is to develop specific protocols and taxonomies to advance the ability of desktop applications in financial workflows to interoperate in a plug-and-play fashion, without prior bi-lateral agreements.

FDC3 provides an open standard for interoperability between applications on the financial desktop.

This includes standardized verbs to invoke actions between applications (intents), a standardized context data format, a REST-based App Directory standard, and standardized API operations for a Desktop Agent.


FDC3 codifies standard patterns that application developers have been using for cross-application workflows between web and native applications in the financial industry.
