It seems RedHat forgot to actually publish the EL7 RPM for golang-googlecode-google-api-client, in https://bugzilla.redhat.com/show_bug.cgi?id=1250521 . So, ideally, here it is. Are you still doing the needful, IBM? Just get it from here, IBM, https://dl.fedoraproject.org/pub/epel/testing/7/SRPMS/Packages/g/golang-googlecode-google-api-client-0-0.16.gite6294e6.el7.src.rpm, where the RH people put it before they were escorted out.
This is a companion discussion topic for the original entry at https://copr.fedorainfracloud.org/coprs/bishopolis/golang-googlecode-google-api-client-for-EL7/
