          # Client for the CloudChannelService service.
          #
          # CloudChannelService lets Google cloud resellers and distributors manage
          # their customers, channel partners, entitlements, and reports.
          #
          # Using this service:
          # 1. Resellers and distributors can manage a customer entity.
          # 2. Distributors can register an authorized reseller in their channel and
          #    provide them with delegated admin access.
          # 3. Resellers and distributors can manage customer entitlements.
          #
          # CloudChannelService exposes the following resources:
          # - {::Google::Cloud::Channel::V1::Customer Customer}s: An entity—usually an enterprise—managed by a reseller or
          # distributor.
          #
          # - {::Google::Cloud::Channel::V1::Entitlement Entitlement}s: An entity that provides a customer with the means to use
          # a service. Entitlements are created or updated as a result of a successful
          # fulfillment.
          #
          # - {::Google::Cloud::Channel::V1::ChannelPartnerLink ChannelPartnerLink}s: An entity that identifies links between
          # distributors and their indirect resellers in a channel.
