how to pass data between requests code example

Example: how to pass data between requests

To pass data between requests in postman

I would use Enviroment or Global Variable
Lets say I want to pass my token between
requests. Than I would create empty global
variable and save the entire token response
as json and print the accessToken from 
response and set the value of global variable
to json field by writing like for example:

var responseJson = pm.response.json(); 
console.log( responseJson.accessToken  );
pm.globals.set("my_secret_token",  responseJson.accessToken );
