FactSet Enterprise SDK

Apache-2 license

The FactSet Enterprise SDK is a collection of client libraries designed to make it easier to use FactSet's APIs in .NET, Java, Python and TypeScript/JavaScript (Node.js). For more information on what APIs are available and how to subscribe, please see the Developer Portal.


The FactSet Enterprise SDK is made up of two main components, API client libraries and utility libraries. The API client libraries are auto-generated for .NET, Java, Python and TypeScript/JavaScript using the OpenAPI Generator based on the OpenAPI specifications published on the Developer Portal. Whereas the utility libraries are handwritten and contain shared functionality that spans all APIs, such as authentication logic.

The auto-generated source code for the API client libraries can be found in the code/ directory of this repository, which contains language-specific sub-directories and API-specific sub-directories under each language (e.g. code/python/PAEngine).

Language Client libraries Utility library
.NET .NET source .NET utilities
Java Java source Java utilities
Python Python source Python utilities
TypeScript/JavaScript TypeScript/JavaScript source TypeScript utilities


  • Software Development Kit (SDK) - A programming-language-specific group of client libraries that a FactSet customer can use to programmatically access FactSet content and analytics.
  • Client library - a programming-language-specific module that contains a grouping of related logic. Each SDK is made up of one or more client libraries. When implementing an application or service that depends on FactSet APIs, a customer would leverage one or more client libraries.
  • Package - a client library that has been built for distribution to customers, often through a package manager like PyPi, Maven Central, NuGet or NPM.
  • Semantic Versioning - a common specification for versioning software, where a version number looks like MAJOR.MINOR.PATCH (e.g. 1.2.3).
    • MAJOR - incremented when there is a breaking change, like changing a response type adding a new required parameter or changing status codes.
    • MINOR - incremented when functionality is added in a backward compatible way, like adding a new endpoint, adding new optional query string arguments or adding a new optional property to the request body.
    • PATCH - incremented when a backwards-compatible bug fix is added, like fixing a typo in documentation.


Each API and utility library is published as its own package to the following package managers:

  • .NET - NuGet (FactSet.SDK prefix)
  • Java - Maven (com.factset.sdk group ID)
  • Python - PyPI (fds.sdk prefix)
  • TypeScript/JavaScript - npm (@factset/sdk prefix)

Each library linked above in the overview section also contains embedded sample code to help with getting started.


The FactSet Enterprise SDK supports two forms of authentication, both must be setup through FactSet's Developer Portal.

  1. (preferred) OAuth 2.0 - client credentials flow
  2. API Key
