// 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:
// - [Customer][google.cloud.channel.v1.Customer]s: An entity—usually an enterprise—managed by a reseller or
// distributor.
//
// - [Entitlement][google.cloud.channel.v1.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.
//
// - [ChannelPartnerLink][google.cloud.channel.v1.ChannelPartnerLink]s: An entity that identifies links between
// distributors and their indirect resellers in a channel.
