how can i add the Oauth token to the service Object? / or how can i add it to the header

Can you find the documentation for ->transport?

site:perlmonks.org SOAP::Lite transport add header

-> $soap->transport->default_headers ... transport is LWP::UserAgent

-> $soap->transport->http_request->headers->push_header('Authorization'=>$authoriz);

I tried one line of code someplace somewhere

And then what happened?

"Works" for me (does everything I expect it to do )
