Good morning everyone, I hope you can help me, I have been trying to carry out the postman process with NetSuite, but when trying to create the second step, which corresponds to creating a refresh token, it is not possible for me, I have carried out this with an administrator user, to which I make sure that it has permissions for the login with access oauth2.0 but when I take it to postman in the authorization I am using the created credentials and in the body the code that I generate, the url redirection, the grant_type authorization_code, Content-Type application/x-www-form- urlencoded. But I keep getting the 401 error, can someone help me, I appreciate your help

expect to share the Login Audit Trail details

Thank you very much, when I saw the log I was able to realize where the error was and now I have succeeded, you are the best, thanks for your fast response
