Clearstream API services


The digital world is powered by Application Programming Interfaces (APIs) that allow for seamless interactions between IT systems over standardised specifications.

Improving your connectivity experience

Clearstream has expanded the ClearstreamXact suite of connectivity solutions with a dedicated API (Application Programming Interface) platform available through Xact Web Portal.

The Clearstream API platform exposes business and technical data directly to the IT systems of our customers which allows the integration of customer systems with multiple APIs across products in a seamless and secure manner.

Clearstream API services allow:

  • Integration of customer systems with multiple APIs across products in a seamless and secure manner;
  • Customers’ IT teams to develop specialised and customised software based on our API offering;
  • State-of-the-art interface experience by reducing the reliance on traditional interfaces;
  • Open digital architecture that drives innovation.

User Management (SCIM2) API

The first API available within the Xact Web Portal is the “User Management (SCIM2)”, an industry standard API for user provisioning, maintenance, and monitoring. The User Management (SCIM2) API is primarily intended for developers and administrators in order to integrate the Xact Web Portal user management to create, retrieve, update or delete users without the need to login to the Xact Web Portal GUI.

Additional business-oriented APIs will be launched in the future.
