# API Playground

Proyek sederhana untuk playground API enrollment berbasis Python Bottle dan SQLite.

Aplikasi ini menyediakan halaman UI playground dan API endpoint untuk mengelola data enrollment secara CRUD.

---

## 🚀 Fitur

- Server API berbasis Bottle
- Database SQLite
- UI playground untuk testing endpoint langsung dari browser
- Autentikasi sederhana menggunakan Bearer Token
- Validasi nilai `type` dan `service`

---

## 📋 Requirements

Pastikan sudah terinstall:

- Python 3
- pip3

---

## 🛠️ Instalasi

### 1. Clone / Masuk ke Folder Project

```bash
cd api-playground
```

### 2. Buat Virtual Environment

Disarankan menggunakan virtual environment agar dependency tidak bercampur dengan environment global.

```bash
python3 -m venv venv
```

### 3. Aktifkan Virtual Environment

Di Linux/macOS:

```bash
source venv/bin/activate
```

Di Windows:

```bash
venv\Scripts\activate
```

### 4. Install Dependencies

```bash
pip install -r requirements.txt
```

---

## ▶️ Menjalankan Aplikasi

Jalankan server dengan perintah:

```bash
python app.py
```

Server akan berjalan di:

```bash
http://localhost:8080
```

atau:

```bash
http://0.0.0.0:8080
```

Jika kode diubah, server akan otomatis restart karena menggunakan mode `debug=True` dan `reloader=True`.

---

## 🔐 Autentikasi

Semua request ke endpoint API wajib menyertakan header:

```bash
Authorization: Bearer secret123
```

Token default disimpan di `app.py` pada variabel:

```python
API_TOKEN = "secret123"
```

Jika tidak menyertakan token atau token salah, API akan mengembalikan response `401 Unauthorized`.

---

## 📡 Daftar Endpoint

| Endpoint | Method | Auth | Fungsi |
|---|---|---|---|
| `/` | `GET` | Tidak | Halaman playground UI |
| `/api/enroll` | `GET` | Ya | List semua enrollment |
| `/api/enroll?id=<id>` | `GET` | Ya | Mendapatkan detail enrollment berdasarkan ID |
| `/api/enroll` | `POST` | Ya | Tambah, edit, atau hapus enrollment |

---

## 🧬 Database Schema

Tabel: `enroll`

| Kolom | Tipe | Keterangan |
|---|---|---|
| `id` | INTEGER | Primary key, auto-increment |
| `type` | TEXT | Tipe enrollment, hanya boleh `Annually` atau `Monthly` |
| `service` | TEXT | Paket layanan, hanya boleh `Lite`, `Value`, atau `Pro` |
| `user` | TEXT | Nama pengguna |

---

## 🧪 Penggunaan Endpoint

### 1. List Semua Enrollment

**Request**

```bash
curl -H "Authorization: Bearer secret123" \
  http://localhost:8080/api/enroll
```

**Response**

```json
{
  "data": [
    {
      "id": 2,
      "type": "Monthly",
      "service": "Lite",
      "user": "bob"
    },
    {
      "id": 1,
      "type": "Annually",
      "service": "Pro",
      "user": "alice"
    }
  ]
}
```

---

### 2. Detail Enrollment Berdasarkan ID

**Request**

```bash
curl -H "Authorization: Bearer secret123" \
  "http://localhost:8080/api/enroll?id=1"
```

**Response**

```json
{
  "data": {
    "id": 1,
    "type": "Annually",
    "service": "Pro",
    "user": "alice"
  }
}
```

Jika ID tidak ditemukan:

```json
{
  "error": "not found"
}
```

---

### 3. Tambah Enrollment Baru

Endpoint `POST /api/enroll` dapat menerima data dalam format form-urlencoded atau JSON.

#### Menggunakan Form Data

```bash
curl -X POST http://localhost:8080/api/enroll \
  -H "Authorization: Bearer secret123" \
  -d "type=Annually" \
  -d "service=Pro" \
  -d "user=alice"
```

#### Menggunakan JSON

```bash
curl -X POST http://localhost:8080/api/enroll \
  -H "Authorization: Bearer secret123" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "Annually",
    "service": "Pro",
    "user": "alice"
  }'
```

**Response**

```json
{
  "message": "created",
  "id": 1
}
```

---

### 4. Edit Enrollment

Untuk melakukan edit, kirim field `id` bersama data baru.

#### Menggunakan Form Data

```bash
curl -X POST http://localhost:8080/api/enroll \
  -H "Authorization: Bearer secret123" \
  -d "id=1" \
  -d "type=Monthly" \
  -d "service=Value" \
  -d "user=bob"
```

#### Menggunakan JSON

```bash
curl -X POST http://localhost:8080/api/enroll \
  -H "Authorization: Bearer secret123" \
  -H "Content-Type: application/json" \
  -d '{
    "id": 1,
    "type": "Monthly",
    "service": "Value",
    "user": "bob"
  }'
```

**Response**

```json
{
  "message": "updated",
  "id": 1
}
```

---

### 5. Hapus Enrollment

Untuk menghapus data, gunakan `POST /api/enroll` dengan field:

- `id`
- `action=remove`

#### Menggunakan Form Data

```bash
curl -X POST http://localhost:8080/api/enroll \
  -H "Authorization: Bearer secret123" \
  -d "id=1" \
  -d "action=remove"
```

#### Menggunakan JSON

```bash
curl -X POST http://localhost:8080/api/enroll \
  -H "Authorization: Bearer secret123" \
  -H "Content-Type: application/json" \
  -d '{
    "id": 1,
    "action": "remove"
  }'
```

**Response**

```json
{
  "message": "removed",
  "id": 1
}
```

---

## 🧠 Logika `POST /api/enroll`

```text
POST /api/enroll
│
├── action = "remove"  → hapus data, wajib menyertakan id
├── ada field id       → edit data
└── tidak ada field id → tambah data baru
```

Untuk tambah dan edit, field berikut wajib dikirim:

| Field | Wajib | Keterangan |
|---|---|---|
| `type` | Ya | Harus `Annually` atau `Monthly` |
| `service` | Ya | Harus `Lite`, `Value`, atau `Pro` |
| `user` | Ya | Nama pengguna |

---

## ⚠️ Validasi

Nilai yang diterima API:

```text
type:
- Annually
- Monthly

service:
- Lite
- Value
- Pro
```

Jika nilai tidak sesuai, API akan mengembalikan error `400 Bad Request`.

Contoh error:

```json
{
  "error": "type must be one of: Annually, Monthly"
}
```

```json
{
  "error": "service must be one of: Lite, Value, Pro"
}
```

---

## 🎮 Menggunakan Playground UI

Setelah server berjalan, buka browser ke:

```bash
http://localhost:8080
```

Halaman playground dapat digunakan untuk:

1. Mengisi token Bearer
2. Melihat status autentikasi
3. Mengisi form request
4. Mengirim request ke endpoint
5. Melihat response JSON secara langsung

---

## 🧾 Contoh Response Error

| Status | Kondisi | Response |
|---|---|---|
| `401` | Tidak menyertakan Authorization header | `{"error": "missing or invalid Authorization header"}` |
| `401` | Token tidak valid | `{"error": "invalid token"}` |
| `400` | Field wajib kosong | `{"error": "type, service, user are required"}` |
| `400` | `type` tidak valid | `{"error": "type must be one of: Annually, Monthly"}` |
| `400` | `service` tidak valid | `{"error": "service must be one of: Lite, Value, Pro"}` |
| `400` | `id` bukan integer | `{"error": "id must be an integer"}` |
| `404` | Data tidak ditemukan | `{"error": "not found"}` |
