I have a two step.
step1 : hit API and extract list of id say N number of id
step2 : hit second API N times by passing id one by one.
What version of DevTest are you on?
Thank you for reply my DevTest version is 10.0.0
What you might be able to do is save all of the IDs from the first step to a dataset and then have that dataset be input to the second step for looping. Or you might be able to put the second step in a sub process and loop there.
Refer to these documentation links:
Branching and Looping in a Test Case - DevTest Solutions - 10.0 - CA Technologies Documentation
Building Subprocesses - DevTest Solutions - 10.0 - CA Technologies Documentation
Hope this helps.
