Delete records from Qlik Data Base, Yes
because you can delete an app , task or something like this
Delete Data INSIDE of app, NOT possible , because that not the goal of Rest api, Is connect o Qlik Engine and to do something.
But if you want to delete records using Qlik and send to other Tool ( let use example connect to other app using rest and delete a record) I will say: yes, but is more Qlik can call this rest api creating a data connection, because its more the other app accepting this, then Qlik doing something.
At the end it's you other solution tool, for example Oracle Db accepting an has rest api function to delete base by the record you send, than Qlik doing some Black magic or something out-of-box.
Jus ta reminder: Qlik is visualization you should not use Qlik to do this, if you have SaaS use Automations.
As you think, so shall you become.
