# Frontend API Compatibility Check

## ✅ Endpoint Mapping

Semua endpoint yang dipanggil frontend sudah tersedia di backend:

| Frontend Endpoint | Backend Route | Status | Notes |
|------------------|---------------|--------|-------|
| `/auth/v1/login` | ✅ `POST /auth/v1/login` | OK | JWT authentication |
| `/retribusi/v1/frontend/locations` | ✅ `GET /retribusi/v1/frontend/locations` | OK | Pagination support |
| `/retribusi/v1/frontend/gates` | ✅ `GET /retribusi/v1/frontend/gates` | OK | Filter by location_code |
| `/retribusi/v1/dashboard/summary` | ✅ `GET /retribusi/v1/dashboard/summary` | ✅ FIXED | Date optional (default today), gate_code support |
| `/retribusi/v1/dashboard/daily` | ✅ `GET /retribusi/v1/dashboard/daily` | OK | Requires start_date & end_date |
| `/retribusi/v1/dashboard/by-category` | ✅ `GET /retribusi/v1/dashboard/by-category` | OK | Requires date |
| `/retribusi/v1/summary/daily` | ✅ `GET /retribusi/v1/summary/daily` | OK | Requires date |
| `/retribusi/v1/summary/hourly` | ✅ `GET /retribusi/v1/summary/hourly` | OK | Requires date |
| `/retribusi/v1/realtime/snapshot` | ✅ `GET /retribusi/v1/realtime/snapshot` | OK | Date optional (default today) |
| `/retribusi/v1/frontend/entry-events` | ✅ `GET /retribusi/v1/frontend/entry-events` | OK | Pagination & filters |
| `/retribusi/v1/realtime/events` | ✅ `GET /retribusi/v1/realtime/events` | OK | Pagination & filters |
| `/retribusi/v1/realtime/stream` | ✅ `GET /retribusi/v1/realtime/stream` | OK | SSE stream |

## 🔧 Perbaikan yang Dilakukan

### 1. Dashboard Summary Endpoint
**File**: `api-btekno/src/Modules/Retribusi/Dashboard/DashboardController.php`

**Perubahan**:
- ✅ Parameter `date` sekarang **optional** (default: hari ini)
- ✅ Menambahkan support untuk parameter `gate_code`
- ✅ Response format konsisten: `{ success: true, data: {...} }`

**Sebelum**:
```php
$date = $queryParams['date'] ?? null;
if ($date === null || !is_string($date)) {
    return ResponseHelper::json(..., 422); // Error jika tidak ada
}
```

**Sesudah**:
```php
$date = $queryParams['date'] ?? date('Y-m-d'); // Default ke today
if (!is_string($date)) {
    $date = date('Y-m-d');
}
// Validate format, jika invalid gunakan today
```

### 2. Dashboard Service - getSummary Method
**File**: `api-btekno/src/Modules/Retribusi/Dashboard/DashboardService.php`

**Perubahan**:
- ✅ Menambahkan parameter `$gateCode` untuk filtering
- ✅ Support filter by gate_code di semua query (total_count, total_amount, active_gates, active_locations)

## 📋 Response Format

Semua endpoint menggunakan format konsisten:

**Success Response**:
```json
{
  "success": true,
  "data": { ... },
  "meta": { ... },  // Optional, untuk pagination
  "timestamp": 1234567890
}
```

**Error Response**:
```json
{
  "error": "error_code",
  "message": "Error message",
  "fields": { ... }  // Optional, untuk validation errors
}
```

## 🔍 Frontend API Handler

Frontend sudah handle response format dengan benar di `api.js`:

```javascript
// Unwrap jika response punya { success, data }
if (json && Object.prototype.hasOwnProperty.call(json, 'success') &&
    Object.prototype.hasOwnProperty.call(json, 'data')) {
  return json.data;
}
return json;
```

## ✅ Testing Checklist

- [x] Semua endpoint terdaftar di routes
- [x] Response format konsisten
- [x] Query parameters optional sesuai kebutuhan
- [x] Error handling proper
- [x] CORS middleware aktif
- [x] JWT middleware untuk protected routes
- [x] Pagination support

## 🚀 Next Steps

1. Test koneksi dari frontend ke backend
2. Verify semua endpoint bekerja dengan benar
3. Test error handling (401, 422, 500)
4. Test pagination
5. Test filtering (location_code, gate_code, date range)
