I have exposed several REST APIs from my outsystems application and am able to test it on Postman, indicating it is working properly. 

However, I was trying to set up a test case and consume these APIs but it is not working as intended:

1. Not consuming all the APIs within that endpoint

2.  Unable to modify the input/expected output variables for JSON data type

Please help, I've been stuck on this for a week, not sure where its going wrong.
