## 📚 Dokumentasi

### 📖 Interactive API Documentation

Kunjungi **Swagger UI** di: http://localhost:8080/swagger/index.html

**Cara menggunakan:**

1. 🔑 Login melalui `/auth/login` endpoint
2. 📋 Copy token dari response
3. 🔓 Klik tombol "Authorize" di Swagger
4. 📝 Masukkan: `Bearer <your-token>`
5. ✅ Test semua endpoint yang tersedia

### 🧪 Testing Examples

**JavaScript/Axios:**

```javascript
// Login dan set token
const auth = await axios.post('/api/v1/auth/login', {
  username: 'admin',
  password: 'password'
});

axios.defaults.headers.common['Authorization'] =
  `Bearer ${auth.data.access_token}`;

// Fetch retribusi data
const retribusi = await axios.get('/api/v1/retribusi');
console.log(retribusi.data);
```

**cURL Examples:**

```bash
# Login
TOKEN=$(curl -s -X POST http://localhost:8080/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"password"}' | jq -r '.access_token')

# Get retribusi data
curl -H "Authorization: Bearer $TOKEN" \
  http://localhost:8080/api/v1/retribusi

# Dynamic filtering
curl -H "Authorization: Bearer $TOKEN" \
  "http://localhost:8080/api/v1/retribusi/dynamic?filter[Jenis][_eq]=RETRIBUSI%20PELAYANAN%20KESEHATAN"
```

### 🔍 Health Monitoring

```bash
# Basic health check
curl http://localhost:8080/api/sistem/health

# Database status
curl http://localhost:8080/api/sistem/databases

# System info
curl http://localhost:8080/api/sistem/info
```

**Response:**

```json
{
  "status": "healthy",
  "timestamp": "2025-01-10T05:39:00Z",
  "services": {
    "database": "connected",
    "keycloak": "accessible",
    "bpjs_api": "accessible",
    "satusehat_api": "accessible"
  },
  "version": "1.0.0"
}
```

***

## 🚨 Troubleshooting

### Masalah Umum

**❌ Database Connection Error**

```bash
# Cek status database
make docker-run

# Check logs
docker logs api-service

# Verify environment variables
cat .env | grep DB_
```

**❌ Authentication Error**

- 🔄 Pastikan Keycloak service berjalan
- ✅ Cek KEYCLOAK_ISSUER URL
- 📝 Format token harus: `Bearer <token>`

**❌ Dynamic Filter Error**

- ✅ Pastikan field name sesuai dengan database
- 🔍 Cek syntax filter: `filter[field][operator]=value`
- 📝 Operator yang didukung: `_eq`, `_neq`, `_gt`, `_lt`, `_contains`

### Debug Mode

```bash
# Enable debug logging
export GIN_MODE=debug

# Run dengan verbose output
make run

# Monitor dengan hot reload
make watch
```
