QRS API:

https://help.qlik.com/en-US/sense-developer/June2019/APIs/repositoryserviceapi/index.html

Basically everything you can do in the QMC

Engine JSON API:

https://help.qlik.com/en-US/sense-developer/June2019/APIs/EngineAPI/index.html

Basically everything you can do in the Qlik Sense Desktop/Server

Best to check out the links and then see if anything is unclear.

Hi @cpomeren003

So according your answer if we need to see the script for any app we have to use Engine JSON API instead of QRS API, isn't it?

Thanks

Just to add a little bit more info:

- QRS api - anything that can be done in the QMC (streams operations, reload task operations, virtual proxies, app upload/delete etc).

- Engine json api - anything you can do with specific app in the Hub - script operations, reload app, add/remove sheets, add/remove/update objects, make selections, bookmarks, session objects, "interrogate" the app to get data from it etc

And conceptual difference - QRS API is REST based; communication with Engine JSON API is web socket based
