4. What scenarios does the reduced service fee rate apply to?
The reduced service fee rate applies to payment scenarios in WeChat Mini Programs. As long as you send the Mini Program to a WeChat customer in a chat or by using WeCom customer contact tools, such as Broadcast Messages and welcome messages, and the customer opens the Mini Program in WeChat to make payments, the reduced service fee rate applies.

5. Does this feature affect the transaction experience of customers in WeChat?
No, this feature does not affect the transaction experience of customers in WeChat. The WeChat payment experience remains unchanged. After a customer makes a payment in the Mini Program, the API provided by WeCom is called to complete the payment.
The following figure shows the payment process.

6. In addition to using Mini Programs sent from WeCom, are there other ways for customers to use Mini Programs to make payments?
Yes. Customers can search for the Mini Program or swipe down on the WeChat homepage to open the Mini Program, or open the Mini Program sent in WeChat. However, if the Mini Program is not sent from WeCom, the reduced service fee rate does not apply, and risk control rules might be triggered. We recommend that you use your receiving account’s merchant account only in scenarios where the Mini Program is sent from WeCom.

7. How do I track member performance for transactions made in Mini Programs?
(1) For Mini Programs sent from WeCom, you can obtain the scene key from the URL. (The key contains the ID of the member who sends the Mini Program.)
(2) Include the scene key in the request when you call the payment API.
(3) Then, you can view the member’s performance for transactions made in Mini Programs in “Receive Money from External” -> “Member Performance” in the Admin Console.
For example:
Assume that the URL of the product details page of a Mini Program is /page/detail?userid=xxx
When a member sends this page in WeCom, a scene key is added to the URL. The URL becomes /page/detail?userid=xxx&scenekey=asdf1234
You can parse the scenekey parameter in functions such as App.onLaunch or Page.onLoad and include the key in the request of the payment API. Then, the member ID is parsed and the performance data is available in the Admin Console.

8. Why can’t business owners see the Mini Program performance data for members in their allowed scope?
The Mini Program performance data is not available if you do not include the scene key in the request when you call the payment API.
