Backend widget: API dashboard

Needs a way to manually refresh the data by tapping on the widget and also in the app to be useful for important data. And a big inconvenience is entering the api info, why can’t I just paste the entire url? Instead I have to type out the domain and path and query strings. Also what’s the difference between url string and a component setup? Also it works if the data returned is an array but have no idea how to select data if an object is returned.
