FDC3 (Financial Desktop Connectivity and Collaboration Consortium) is an open standard hosted by FINOS for interoperability between financial desktop applications. The standard defines how applications launch other apps, share typed context data, raise and resolve intents across the financial desktop, and register themselves in an App Directory. FDC3 eliminates the need for custom bilateral agreements between software vendors and enables plug-and-play integration workflows for financial services firms. Current version is 2.2, licensed under the Community Specification License 1.0 with code released under Apache 2.0.

The FDC3 Desktop Agent API is the primary interface for application interoperability on the
financial desktop. It provides a JavaScript/TypeScript API that applications use to open other
applications, raise intents to request functionality from peer apps, broadcast typed context
data on channels, listen for incoming context and intents, discover available applications and
their capabilities, and create private two-party communication channels. Desktop Agents
implement this API and expose it to the applications they host.

name: FDC3 App Directory API
description: >-
The FDC3 App Directory (AppD) is a REST API standard for registering and discovering
financial desktop applications. Desktop Agents query App Directories to resolve application
definitions when launching apps or resolving intents. The v2 endpoints are the current
standard, supporting retrieval of all app definitions and lookup by appId. Authentication
is supported via HTTP Authorization Bearer JWT tokens. Implementations are provided by
vendors and financial institutions; FINOS publishes the specification and JSON schema.

description: >-
FDC3 Context Data defines a standard set of typed data structures used to carry information
between financial applications when broadcasting or raising intents. Context types include
instruments, positions, portfolios, contacts, organizations, orders, charts, country, currency,
date range, email, and more. Each context type has a JSON schema definition. Applications
share and receive these typed objects through the Desktop Agent API channels and intent
resolution, enabling interoperability without custom data mapping.

FDC3 Intents are standardized verbs that applications use to request functionality from
other applications on the financial desktop. Standard intents include ViewChart, ViewQuote,
ViewNews, ViewAnalysis, ViewInstrument, ViewHoldings, ViewOrders, ViewResearch, ViewProfile,
ViewInteractions, ViewMessages, ViewChat, StartCall, StartChat, StartEmail, CreateInteraction,
and CreateOrUpdateProfile. Applications declare which intents they handle in their App
Directory entry, and the Desktop Agent routes intent requests to appropriate handler apps.

name: FDC3 Desktop Agent Bridging
description: >-
FDC3 Desktop Agent Bridging (DAB) is a wire protocol that enables multiple Desktop Agent
implementations to interoperate, allowing applications running under different Desktop
Agents to share context and raise intents with each other. The bridging specification
defines a WebSocket-based protocol for agent-to-agent communication, enabling cross-agent
context broadcasting and cross-agent intent resolution within the same desktop environment
or across network boundaries.
