I have not done much programming with Go. I primarily use IntelliJ but decided to use emacs for Go. I have it set up to run gofmt on file save. I learned that gofmt uses hard tabs instead of spaces. I posted a question on the mailing list about style guidelines. I can push another commit that reverts the formatting. My only change is on line 821 from:

api.Action.BackendUrl = "https://" + Client.Config.Host + "/api/v1/web/" + qName.GetNamespace() + "/" + urlActionPackage + "/" + qName.GetEntity() + ".http"

to:
api.Action.BackendUrl = Client.Config.BaseUrl.Scheme + "://" + Client.Config.Host + "/api/v1/web/" + qName.GetNamespace() + "/" + urlActionPackage + "/" + qName.GetEntity() + ".http"
