Run a reload from a Qlik Sense mashup

The main use of Qlik Sense mashup API is to visualize data from Qlik Sense apps and reuse visualizations in an app, allowing your users to interact with the data. But you can use it for other things to, like running a reload or interacting with Qlik Sense server.

But a Qlik Sense app can be used in two different contexts: desktop and server. While visualizations and interactions with those work the same in Server and Desktop, the server API (which is a REST API, unlike the QIX Engine API which works over the web socket. So the first thing we need to do is check our environment, are we in Server or Desktop. Luckily, there is a method for that, the isPersonalMode method.

Once we know if we are in Desktop or Server we can acct accordingly. If we are in Desktop, we can just call the doReload method. While this might work in Server too, we really shouldn’t use it. In a server environment you might very likely have different Qix Engines for interaction with the user and reloads. In fact it is very likely that the engine we are connected to does not have the right database connections for the reload, so running the reload there would fail. Instead we call the Qlik Server for the reload, and let it determine which computer should do the actual job. We can do this with the callRepository method.

This would look something like this:

You find a full working example in the Github repository.
