Ok, then you could create a function on the parent element that handles the response/data from the child and pass that function as a prop. Then call that function from the child.
Alternatively, you might have a look at the context API, which provides a way to share values between components without having to pass a prop through every level of the tree.
As a side note, it is often a good idea to do the fetching of data in the parent component and then keep your child components as dumb as possible, just passing them the data they need to display.
