1. Merchant's self-funded mode: Merchants can apply for WeChat applet authentication in WeChat official account, and apply through WeChat payment merchant number. After passing the WeChat applet authentication, the merchant needs to buy a small group program from some software development companies, and after binding the WeChat payment, upload the applet code in the background of the WeChat applet, which can be used after passing the WeChat audit. Merchants can directly use their own applets to publish group activities.
2. Free mode for merchants: At present, the widely used free group-assembling applet includes the "get one free" WeChat applet, which is widely used by many social e-commerce, offline stores, Taobao sellers, training and education institutions, fresh fruits, clothing digital, beauty and fitness, etc. In the WeChat ecosystem, merchants can search and send one and use it directly without investing in software development funds.
