Fetch data from one app and fill it into other app via uipath

I am new to UiPath. I want to automate the API testing process done through postman app. I want to access the UiPath robot through REST API and pass some parameters like URL and Method (GET/POST) to the API to test the URL received through JSON body/payload using postman application. Could anyone please help me with the steps or process?
