How to add additional header along with wsse. For example.

I have already add line below client = Client(url, wsse=UsernameToken(user, password), plugins=[history])

How to add additional header like X-Validate_only:1 ?

Thanks

Did you try adding it to the _soapheaders? https://docs.python-zeep.org/en/master/headers.html
