How to Extract response header value in postman?

Question

How can I fetch the value of a response header in postman and save it in a variable so that I can use it in the next request?

Example:

HeaderName: HeaderValue
AESKey: ndowijdw92n9992n

I need to fetch ndowijdw92n9992n and send it to the next request.

There is more direct way to access AESKey header:

const responseHeaderAESKey = pm.response.headers.get("AESKey");
pm.environment.set("AESKey", responseHeaderAESKey );

Now the environment variable set contains the AESKey and you can access it in any part of Postman request with {{AESKey}}. So use it in the next request.
