+# Common Integration Patterns
+
+**Purpose:** Common patterns and best practices for Daily Notification Plugin integration.  
+**Owner:** Development Team  
+**Last Updated:** 2025-12-22  
+**Status:** active
+
+---
+
+## Error Handling
+
+```typescript
+import { DailyNotification, DailyNotificationError, ErrorCode } from '@timesafari/daily-notification-plugin';
+
+try {
+  await DailyNotification.createSchedule({
+    id: 'daily-morning',
+    kind: 'notify',
+    clockTime: '09:00',
+    enabled: true
+  });
+} catch (error) {
+  if (error instanceof DailyNotificationError) {
+    switch (error.code) {
+      case ErrorCode.PERMISSION_DENIED:
+        // Request permission first
+        await DailyNotification.requestPermission();
+        break;
+      case ErrorCode.INVALID_TIME_FORMAT:
+        // Fix time format (use HH:mm)
+        console.error('Invalid time format');
+        break;
+      default:
+        console.error('Error:', error.message);
+    }
+  }
+}
+```
+
+## Scheduling Multiple Notifications
+
+```typescript
+const times = ['09:00', '12:00', '18:00'];
+
+for (const time of times) {
+  await DailyNotification.createSchedule({
+    id: `daily-${time.replace(':', '')}`,
+    kind: 'notify',
+    clockTime: time,
+    enabled: true
+  });
+}
+```
+
+## Checking Schedule Status
+
+```typescript
+const { schedules } = await DailyNotification.getSchedulesWithStatus();
+
+schedules.forEach(schedule => {
+  console.log(`${schedule.id}: ${schedule.status} (scheduled: ${schedule.isActuallyScheduled})`);
+});
+```
+
+## Recovery After App Restart
+
+The plugin automatically recovers missed notifications on app launch. To check recovery status:
+
+```typescript
+// Recovery happens automatically on app launch
+// Check history for recovery events
+const { history } = await DailyNotification.getHistory({
+  kind: 'recovery',
+  limit: 10
+});
+```
