If you are testing REST APIs application with Oauth on Postman, generally you do the following,
- Send a OAUTH request to an /auth endpoint and copying the access token, and setting header as ‘Bearer <access-token>’ in actual request.
- This copy-paste be avoided if you set following pre-request script in pre-request tab
This will execute the Oauth request before executing the actual REST
API, and store in a global variable. So consecutive calls will utilize
the stored global variable.
Above works great for a single cluster setup.
However for a multi cluster setup, where you have one cluster in say EU data center, another in US, then you would need to duplicate this setup. I have seen developers Postman flooded with hundreds of similar requests, with only change being the URL, like below with over 184 requests
This can be avoided by using environment variables.
I have modified the pre-request script to store the access tokens, refresh token as a value object in a map with key being the cluster url. This url is set via the environment variables.
So now I can switch to different clusters easily by switching the environment.
