Display Dynamic API Data

I have two API collections:

https://test-data.com/users/list
https://test-data.com/users/105111

The first endpoint displays all users and their relevant information such as unique ID which I have in a collections list:

The second endpoint displays more user information for the given ID inputed. I would like to create a child card inside the collection list so the endpoint can display the corresponding user information. Given the example above, the send API endpoint will only display “User 1” information. How would I achieve this so the send API endpoint can pull the variable from the current user ID in each collection list item?

You can do a POST rest api request with your parameter based on the docs of your api. For the variable, you need to use the one from your context I think.
