Hello,  
We are trying to generate the access token using postman Auth Type = OAuth 2.0 and to use the token for SAS application. For Grant Type I am using Grant Type = Authorization Code. Then I click on Get Access New Token and it asks for authentication. After successful authentication it creates the Access\_Token.

questions :

1. We can see the Access Token created as json file in Console tab \> POST \> Response Body. Please find the screenshot. Is it possible to directly save the json file locally ? or where the Json file is getting saved ?

2. Is it possible to automate the whole process (to trigger with shell script) and run the postman script to generate the access token ?
