How to loop a request in Postman?

Question

API

We receive data using a request.
There is a lot of data, 100 lines are issued.
Also, on each page, a key is given, which we must substitute in a new request.
How can we loop the request and also substitute a new key from the field?
Tell me where to google or an example of a request, I'm new.
I am able to execute requests, but I did not write scripts.
Postman client.
