This module is a bit of a work in progress and may not work as expected but is getting some love to build on the work of the author Pavel Serikov. For now the best usage other than the Calendar API is to use the direct API call with manually constructed URI's with parameters as suggested in the other posts. The package includes a utility goauth for generating OAUTH tokens which is useful but be aware that the current cpan version has hard coded scopes. There is the start of some cool use of Google Discovery API to autogenerate access classes but this doesn't quite work for nested methods. If you are going to use this module I suggest that you look at the forks of the original Github repo at https://github.com/pavelsr/moo-google
