Chain array of ids from one request to other

Have a look at the following post, which may achieve what you are attempting to do. The logic will be similar for doing what you need.

Another data driven approach

I’ve seen a few posts now where the poster would like to run all of the requests in a collection\folder, but needs to run a particular request in the collection\folder x number of times using a data driven approach. Currently with Postman, the whole collection\folder will run once for each line in the CSV or JSON file. Typical use case would be where the tester wants to authenticate once and then run x number of tests after authentication. There might be two or three steps that need to happen…

However, I’m not quite following your logic here.

Sounds like you should get a single run ID at a time, which would then enable the two following GET requests to follow in order without you having to create loops in code. Can you format your CSV file so there is one runID on each line? So the test runner can handle the loop.
