Thanks for your answer.
I tried to regenerate the secret and it was not possible, i received the error: failed_to_regenerate_secret.
As i said, it was working yesterday, then i created a new app, and this one works perfectly. Then i suppose is not my postman configuration, but i will try to generete a new token tomorrow and verify that is not a limitation or misconfiguration of my zoom app or account.
I found a thread with the same problem, and it also doesn’t have any solution.
But is a bit crazy that de last app was working fine yesterday and now is just broken.
