Use this API to obtain the Mini Program App ID synchronously without requiring callbacks or promises.

​
Return Value

PropertyTypeDescription
appIdStringThe identifier of the current Mini Program
The returned App ID depends on the deployment context:
  • Deployed to AlipayCN: Returns the ID assigned by AlipayCN
  • Other deployments: Returns the ID assigned by Mini Program Platform

​
Code Example

// Get App ID synchronously
const result = my.getAppIdSync();
console.log('App ID:', result.appId);

// Use in page
Page({
  onLoad() {
    const { appId } = my.getAppIdSync();
    this.setData({ appId });
  },

  data: {
    appId: ''
  }
});

​
Use Cases

​
Conditional Logic Based on App ID

Page({
  onLoad() {
    const { appId } = my.getAppIdSync();

    // Different behavior for different app versions
    if (appId === 'your-production-app-id') {
      this.initProductionFeatures();
    } else {
      this.initDevelopmentFeatures();
    }
  }
});

​
Logging and Analytics

function logEvent(eventName, data) {
  const { appId } = my.getAppIdSync();

  my.request({
    url: 'https://analytics.example.com/log',
    method: 'POST',
    data: {
      appId,
      event: eventName,
      ...data
    }
  });
}

​
Notes

  • This is a synchronous operation that returns immediately
  • The App ID is stable and does not change during the Mini Program lifecycle
  • For AlipayCN deployments, cross-reference with the Mini Program Platform to find the official Mini Program ID
