How Tencent Cloud Built a Mobile Assistant for B2B Users via WeChat

When B2B users try to manage Tencent Cloud services, they often face three major obstacles: high operational complexity with multiple permissions and verification steps, limited access during travel or off‑hours, and ineffective notification channels that rely on SMS and email, which are easily ignored.

To address these issues, the team set a goal of mobile‑enabling the Tencent Cloud console, starting with a systematic exploration of suitable platforms.

1. Choose the Right Mobile Platform

The team evaluated existing resources and concluded that the WeChat ecosystem—specifically a public account (service‑type) and a mini‑program—could host the required mobile capabilities. The public account offers information display, subscription, and push messaging, while the mini‑program supports functional usage, account management, and tooling.

2. Map Cloud Services to Mobile‑Friendly Capabilities

Given Tencent Cloud’s 23 product categories and over 150 services, only a subset could realistically be mobile‑enabled. The team focused on capabilities that improve efficiency, such as information display, notifications, and resource management. They also discovered a critical identity challenge: public accounts identify users by openid , while mini‑programs use UIN . By linking both to the WeChat Open Platform, a unionID is provided, enabling a unified user identity across the two channels.

The team also compared this approach with AWS’s mobile app, which only offers read‑only views and received negative user feedback for lacking transactional capabilities.

3. Use Platform Propagation to Drive User Acquisition

By leveraging the public account’s built‑in promotion tools (custom menus, template messages, QR codes), the team could funnel users into the mini‑program without needing separate marketing for each. For example, a balance reminder sent via the public account includes a clickable card that opens the mini‑program’s recharge page, dramatically improving conversion compared to SMS or email.

4. Refine Product Details and User Experience

Contrary to the belief that B2B tools need not prioritize UX, the team emphasized visual clarity and interaction efficiency. Examples include simplifying the server list to highlight frequent actions, adding virtual avatars in the personal center to replace raw IDs, and ensuring consistent design language across the public account and mini‑program.

These refinements were validated through data analysis, showing increased user satisfaction and higher click‑through rates.

Conclusion

By combining the WeChat public account as an information carrier with a mini‑program as the management interface, the team delivered “Tencent Cloud Assistant,” a mobile product serving tens of thousands of users. The solution improves efficiency, enhances user experience, and opens new channels for service delivery. Future plans include expanding connectivity, tooling, and developer ecosystem integration.
