title: Is there a way in Postman to store multiple values for one key?
body: <p>I am working on side-project using ASP.Net Core web api. I am currently using Postman so I can interact with custom middleware. As you can see in the picture I have a User id and would like the request header to have more than one value for the user id key. Everytime I debug the api, the request header only counts one value instead of two values. I have looked at the Postman help page but it doesn't really cover any material regarding my issue. So to condense my question, is there a way in Postman that a key (For my scenario, User Id) can hold more than one value.</p>
