I'll check in the agency if this document is valid, and then I'll call you back to inform you you should send it attached to the authorization till then, thanks a lot

Maybe you should put "at" instead of "in".
Maybe you should take out "it up" after "check" and maybe either replace "if this" with "whether" or add "to see3
The words "send" and "authorisation" have spelling mistakes.
A comma between "you" and "you" would make it easier to read and either a full stop or a comma after "authorisation".
The text would then read "I'll check at the agency to see if this..."
