WeChat Mini App

The WeChat integration ships a bridge between Unity and the Tencent Mini Program runtime for launching VPS-enabled AR content inside the WeChat ecosystem. Access is limited to Enterprise contracts.

Enterprise Access​

  • Provide your Tencent developer account ID, target provinces, and mini program review schedule when contacting support@web-ar.studio.
  • After approval you will receive:
    • com.webarvps.vps.wechat Unity package.
    • A WeChat Mini Program scaffold with secure API proxying.
    • CI/CD templates for packaging Unity WebGL builds into the WeChat asset bundle format.

Enterprise only: The WeChat transport layer, analytics hooks, and mini program templates are not distributed publicly.

Prerequisites​

  • Approved WeChat Mini Program account with AR permissions.
  • Unity 2022.3 LTS with WebGL build support.
  • Access to the WebAR³ WeChat proxy endpoint (Enterprise entitlement).

Setup Steps​

  1. Add the Enterprise registry and install com.webarvps.vps.wechat.
  2. Build your scene for WebGL using the AR Clip template; enable Offscreen Rendering in Player Settings.
  3. Run the provided wechat-packager CLI to wrap the build output into a Mini Program asset.
  4. Configure the API proxy by setting WECHAT_VPS_PROXY_URL in Assets/WebARStudio/Wechat/Resources/Config.asset.
  5. Deploy to the WeChat developer console and test via the Mini Program dev tools.

Testing Checklist​

  • Verify login and signature validation using your Tencent sandbox credentials.
  • Run localization in both Wi-Fi and cellular scenarios to ensure low-latency frame uploads.
  • Confirm analytic events reach the WeChat data dashboard via the bundled telemetry plugin.
  • Test graceful fallback to 2D content if camera permission is denied.

Support​

Enterprise support includes help with Tencent security reviews, traffic quota sizing, and joint debugging sessions with WebAR³ engineers.
