Refresh token automatically via Postman

Question

When testing some API, the token need to be generated each 3min and I would like to do the refresh automatically, I did the following

I have a collection CollectionGetter which contain some requests

• from CollectionGetter collection :

1. I've added the following script in "Tests" tab

   var jsonData = pm.response.json();  
   pm.environment.set('getToken', jsonData.access_token);
   

2. on authorisation tab, set:

   Type = Bearer token 
   Token {{getToken}}
   

then selected a request under CollectionGetter:

getAccount  (GET url/api/account)
Auth = inherit autho from parent

and sent it

=> got a 401 JSONError: No data, empty input at 1:1

Any help? Is my configuration correct?

Answer 1

Postman now has a feature that auto refresh auth tokens, you just need to setup authentication at the collection level and togle "the auto refresh access token" option: Image showing the auto refresh access token button

here's postman walktrough video about that feature, worth a watch: https://www.youtube.com/watch?v=FAhs9TBK-xU

TLDW:

1 - Click on your collection, it'll open the "auth" tab.

2 - Configure you Authentication type with Oauth 2.0

3 - Scroll to the bottom of the page and set your credentials and click "get new access token"

4 - Go up and togle the "Auto-refresh access token" option: Auto-refresh access token option

5 - With your token already generated go to your request, open the authorization tab of the request and set "type" to "inherit auth from parent", everything should work just fine.

*for testinging local in postman , Best method to set bearer token for all the request quick and easy way is, first you create a bearertoken with validity for more than 1 year(so it will not ask expired ) and copy ,and click on the postman collection top of the folder , if collection is

commonapi>1)loginapi >2)signupapi >3)homescreenapi

, like this format , click on top folder name commonapi, and there you can set bearertoken and paste the value , now in loginapi and all the below subfolder apis we can just set inherit auth from parent , so we dont need to create and set everytime bearer token again and again ,and it will save more time.*
