Hello,

It seems the code you entered is not valid or has expired. the code UUID is short-lived and can only be used once.

Thank You,

Hi Raja, 

Did you get any solution for your invalid grant error? I am facing the same issue even if I use the code and state just after getting it.

Please send the solution if it resolved.

Thanks,
