Add a new Test Cases into Newly created Test Cycle via API

Hello all,

I would like to know how should I add a new test cases into created Test Cycle. 

In short I already created a test cycle through API, now I want to add a new test cases into the cycle. Note that the whole project is new so no test are present.

This is what I want to do. I have several API tests in my Java project. Before the run I create the test cycle (which is working fine), after the creation I execute those API tests and after that I would like to create the text case into the previously created test cycle and send the status (pass or fail).

I am getting the API endpoints from the following site:

https://zfjcloud.docs.apiary.io/#reference/execution/add-tests-to-folder/create-execution

Is it possible in that way?

Is there an option to do that?

How can I create these test cases in the test cycle?

PS: I use Postman for now

Thanks for the tips
