 ### Configuration
 
 The path to the **Credentials JSON** file can be configured instead of storing
 it in an environment variable. Either on an individual client initialization:
 
 ```ruby
 require "google/cloud/channel/v1"
 
-client = ::Google::Cloud::Channel::V1::CloudChannelService::Client.new do |config|
+client = ::Google::Cloud::Channel::V1::CloudChannelReportsService::Client.new do |config|
   config.credentials = "path/to/keyfile.json"

 require "google/cloud/channel/v1"
