Manage in Jmeter the Expiration time of a Token

Normally when you're getting the token you're getting its TTL as well which could be extracted into a JMeter Variable

So you have 2 options:

1. Either periodically send the request for the token refresh in another Thread Group (token TTL minus some reasonable number of seconds), the pause between "refreshes" can be introduced using Constant Timer or Flow Control Action sampler

2. Or make the token refresh a part of the main Thread Group.

   • When you create/refresh the token you can get the current timestamp using time() function and store it into a JMeter Variable
   • Then the current time can be compared to the token refresh timestamp in the If Controller so you will be able to run the refresh request before the current token expires
