Handling a dynamic refresh token on JMeter

Question

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.

The access token is something you're getting as the result of the OAuth 2.0 authorization code flow

It's not a single request, it's a series of requests which you need to implement somehow:

the options are in:

• simulating the same requests sequence as the real browser does (can be recorded and replayed after applying some correlation of the dynamic parameters)
• or using Azure Identity client library for Java from suitable JSR223 Test Element
