## ✅ What Was Implemented

### 1. Backend API (100% Complete)

**File:** `includes/Api/NotificationsController.php`

**New Endpoints:**
- `GET /woonoow/v1/notifications/staff/events` - Returns staff-only events
- `GET /woonoow/v1/notifications/customer/events` - Returns customer-only events

**Changes:**
- Added `recipient_type` field to all events (`'staff'` or `'customer'`)
- Created `get_all_events()` private helper method
- Implemented filtering logic based on `recipient_type`
- All existing endpoints remain functional

**Event Classification:**
```php
Staff Events (recipient_type: 'staff'):
- order_placed (New order notification for admin)
- order_cancelled (Order cancellation alert)
- low_stock (Low stock alert)
- out_of_stock (Out of stock alert)

Customer Events (recipient_type: 'customer'):
- order_processing (Order is being processed)
- order_completed (Order completed)
- order_refunded (Order refunded)
- new_customer (New account created)
- customer_note (Note added to order)
```

```

---

## 🐛 Bugs Fixed

### Issue 1: Staff Route Not Working
**Problem:** `/settings/notifications/staff` showed blank page  
**Cause:** Route not registered in App.tsx  
**Fix:** Added route registration and fixed import paths

### Issue 2: Customer Channels Inconsistent with Staff
**Problem:** Customer Channels page had different layout than Staff  
**Cause:** Different component structure  
**Fix:** Matched Customer Channels layout to Staff with addon section

### Issue 3: Customer Events Showing "No Events"
**Problem:** Customer Events tab showed "No Events" message  
**Cause:** Backend filtering logic using `reset()` on channels array  
**Fix:** Changed to use `recipient_type` field for filtering
