I have recorded JMeter script for a website.
One of the HTTP request is the below screenshot where a refresh_token is already set as a hard-coded parameter when I recorded the script first time. This HTTP request uses this refresh token to post a request and obtain an access token and the access token is used in the subsequent API requests.
My problem is, the refresh token expires after 24 hours and since this refresh token is not obtained as a response from any of the previous HTTP requests, I am unsure how to use a regex extractor to corelate it.
Any help would be appreciated.
