aid: fdc3 name: FDC3 description: >- 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.

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. humanURL: https://fdc3.finos.org/docs/api/spec baseURL: https://fdc3.finos.org tags: - Desktop Agent - Intents - Context Sharing - Channels - Financial Services - Open Standard properties: - type: Documentation url: https://fdc3.finos.org/docs/api/spec - type: Reference url: https://fdc3.finos.org/docs/api/ref/DesktopAgent - type: GitHubRepository url: https://github.com/finos/FDC3 - type: TypeScriptSDK url: https://www.npmjs.com/package/@finos/fdc3 - type: Changelog url: https://github.com/finos/FDC3/blob/main/CHANGELOG.md - type: OpenSource url: https://github.com/finos/FDC3/blob/main/LICENSE.md - aid: fdc3:app-directory-api 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. humanURL: https://fdc3.finos.org/docs/app-directory/spec baseURL: https://appd.example.com tags: - App Directory - Application Registry - REST API - Financial Services - Open Standard properties: - type: Documentation url: https://fdc3.finos.org/docs/app-directory/spec - type: OpenAPISpec url: https://fdc3.finos.org/schemas/2.2/app-directory.html - type: JSONSchema url: https://fdc3.finos.org/schemas/2.2/appd.schema.json - type: GitHubRepository url: https://github.com/finos/FDC3 - type: Reference url: https://fdc3.finos.org/docs/app-directory/overview - aid: fdc3:context-data name: FDC3 Context Data 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. humanURL: https://fdc3.finos.org/docs/context/spec baseURL: https://fdc3.finos.org tags: - Context Data - JSON Schema - Financial Data - Instruments - Open Standard properties: - type: Documentation url: https://fdc3.finos.org/docs/context/spec - type: JSONSchema url: https://fdc3.finos.org/schemas/2.2/context/ - type: Reference url: https://fdc3.finos.org/docs/context/ref/Instrument - type: GitHubRepository url: https://github.com/finos/FDC3 - aid: fdc3:intents name: FDC3 Intents description: >- 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. humanURL: https://fdc3.finos.org/docs/intents/spec baseURL: https://fdc3.finos.org tags: - Intents - Interoperability - Financial Services - Workflow - Open Standard properties: - type: Documentation url: https://fdc3.finos.org/docs/intents/spec - type: Reference url: https://fdc3.finos.org/docs/intents/ref/ViewChart - type: GitHubRepository url: https://github.com/finos/FDC3 - aid: fdc3:desktop-agent-bridging 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.
