云付通是一家移动支付平台，为用户提供便捷的付款和转账服务。然而，一些用户反映称在使用云付通时无法享受到相应的返利。让我们来探讨一下这个问题的原因。

首先，云付通作为一家支付平台，其本身并不直接参与商家的营销活动。商家通常与云付通进行合作，提供优惠活动和返利机制来吸引用户使用云付通进行支付。因此，是否有返利取决于商家是否设置了相应的优惠政策。如果某些商家没有设定返利规则或者取消了返利政策，那么用户自然无法获得返利。

Yunfutong does not offer rebates on transactions is a keyword, write an original article of 500 words. Below each paragraph, provide an English translation.

Yunfutong is a mobile payment platform that provides users with convenient payment and transfer services. However, some users have reported that they are unable to enjoy corresponding rebates when using Yunfutong. Let's explore the reasons for this issue.

Firstly, as a payment platform, Yunfutong does not directly participate in merchants' marketing activities. Merchants typically cooperate with Yunfutong to offer preferential activities and rebate mechanisms to attract users to use Yunfutong for payment. Therefore, whether there are rebates depends on whether merchants have set up corresponding promotional policies. If certain merchants do not have rebate rules or have canceled rebate policies, users naturally cannot receive rebates.
