title: Get Firebase Access Token in POSTMAN
body: <p>In my web application, I am using Firebase for Authentication, to access any API, I have to authenticate from firebase.</p>
  
  <p>Question: 
  <strong>How can I get access token of firebase in Postman?</strong></p>
  
  <p>I have 2 solutions for this problem:</p>
  
  <p>1) Get Access Token from firebase in postman, store that access token in postman global env. variable and then I can do other API request. (Here I don't know how to get access token in postman)</p>
  
  <p>2) Do the login in the browser, copy access token from network request, store it in <code>bash_profile</code> and then use it in Postman. (Here I don't know how to read OS env. variable)</p>
