Implement e2e-test with real backend API without touching real database, third-party service hitting.

[orlantotes]

I would like to implement e2e-testing using cypress in our React.js front-end by calling real backend API.
The purpose of this test will be to test backend API through front-end.
But I have no idea how I shoud organize project structure for test.
I know my idea is special case.
I say again, I don't want to change database by calling real API. But to test api in front-end during e2e-test. I want to call real API without mocking api response.
Is it possible in cypress context?
If possible, please help me to structure e2e-test.
Thank you.
