Is it possible to trigger 3rd party systems from inside dashboards / visualizations?

Hello Leilani,

This is possible in your embedded dashboards or analytical designer. You can set up drill events, that will allow you to drill to records outside of GoodData. Your parent application, in which you have the dashboards/AD embedded, will be able to capture certain events from GoodData and trigger actions based on these events.

We have this documented on following pages:
