When user try to share status then very rare rest api respond with below error message:-

[{"code":64,"message":"Your account is suspended and is not permitted to access this feature."}]

I’m not able to figure out their exact reason why users receiving this error. I evaluate my source code and its look fine.

Any help really appreciated.

Thanks in advance.

Either their account got suspended, which they’ll be notified of via email and when they try to login to Twitter, or there’s a bug with Twitter’s api sending the wrong error code (most likely not this one).

That sounds strange - do preceding and following calls to the same endpoint work without any errors?

Yes and this happen to very few users.
