Good day, is it possible to program an earning app with zappter? In other words, an app with which users can earn money. The marketplace function should remain intact. So that I can create individual tasks with limits and the user gets a fixed reward for it. If this same task is posted again, it should no longer be displayed for the people who have already completed it. And the users can exchange their points for vouchers. Furthermore, I should be able to manually confirm that the task has been completed and only then are the points credited.
I would appreciate helpful answers!
