# Note

# 1 The relationship between customized version trading components and live streaming via WeChat Channels

The custom version transaction component is the foundation for live streaming via WeChat Channels, Weixin Mini Program, and once the custom version transaction component is integrated and the live streaming scenario is approved by WeChat Channels, the mini-program will be granted the authority to bind WeChat Channels and conduct live streaming.

# 2 How to utilize the customized version trading component in live streaming via WeChat Channels

After binding WeChat Channels, the WeChat Channels shopping list can only pull products that have been uploaded via the custom version transaction component and have been approved, and when users place orders in the WeChat Channels scenario,Weixin Mini Program needs to call the order placement interface of the transaction component to complete the user's payment purchase according to the requirements. After payment of the purchase, the logistics and after-sales conditions need to be updated according to requirements. Any order generated in the live room is a live order.

# 3 Ways to Handle Orders Placed During Live Streams for Non-Uploaded Items on WeChat Channels

Using the order interface, the required items in the order are uploaded in real time as required, the order is placed and verified according to the customised transaction component's order placement process, and the payment can be completed after it is passed. In the meantime, the goods do not need to be audited in advance.

# 4 What is the specific meaning of a sub-scenario audit

Users only need to upload the goods used in the scenario and place orders as required by the customised transaction component when placing orders in the scenario.

# 5 After-sales and logistics interfaces and order synchronization interfaces cannot be synchronized in stages

Because all custom component-generated orders are displayed in the Find > Weixin Mini Program > Order Center, and in the Live Room > Merchandise List > Orders portal, the interface needs to be synchronized to ensure consistency in the user experience.

# 6 Testing of goods, orders, etc.

The uploading of goods, the creation of orders, etc. does not depend on the environment, it is the developer's own decision, and can be uploaded and generated in a formal environment or in a test environment. You can see your own goods and order content through the pull-up interface for items, orders, etc. The testing of live streaming via WeChat Channels needs to be conducted in a formal environment, and it is recommended to conduct the testing with a limited number of users and through a whitelist live streaming method.

# 7 Methods by which users handle purchases through additional purchases, repurchases, etc.

The component verifies the order only in scenarios where verification is required, without distinguishing between purchase / business logic, i.e. no requirement to verify the order regardless of the settlement method as long as it is not a limited purchase scenario.
