A Qlik server-side extension protocol for extending the Qlik built-in expression library with functionality from external calculation engines.

Server Side Extension

This repository provides a server-side extension (SSE) protocol based on gRPC that allows you to extend the Qlik built-in expression library with functionality from external calculation engines. You can use external calculation engines in both load scripts and charts. In Qlik Sense and QlikView, you connect to these server-side extensions (SSEs) by defining analytic connections.

This repository includes documentation that describes the SSE protocol, how to use it and how to build your own plugins. We have also examples written in a couple of different languages.
