Postman Automatic Auth Token

Postman can run JavaScript commands when executing a request. These commands can be placed in the "Tests" tab inside a request.
For example, to automatically set a token as a collection variable, the following commands are used: 

```
var auth = pm.response.headers.get("Authorization");
pm.collectionVariables.set('token', auth.split(" ")[1]);
```
