I'm happy to announce the release of version 12.1.0 of the AdWords API
Client Library for Ruby (adwords4r).
Version 12.1.0 removes support for v11 of the AdWords API, which has
been deco'ed. It also includes two new sample programs, one of which
illustrates the full campaign/ad group/creative/criterion creation
process, and the other which shows how to use the methods of the
AccountService to retrieve information about the accounts your MCC
The Google Code page for the adwords4r library is at
and you can download a packaged .gem file of 12.1.0 there.
Alternatively, you can install the later version using the command
line gem tool by running
gem install adwords4r
