I am trying to create a program that will search for availabilities for exams on ProScheduler.

After checking network logs, I can extract the curl command which searches for the set exams using their API.
When i copy this as curl into my terminal, I can use this for 5seconds until i get 401 error.

When digging more, I can see that before the POST request there is a OPTIONS request which possibly updates a cookie to update the timeout of a token?

Please could anyone advise.
