+# 📖 API Enroll Documentation
+
+**Base URL:** `http://localhost:8080`
+
+**Endpoint:** `/api/enroll`
+
+Seluruh operasi CRUD dilakukan melalui **satu endpoint** ini, cukup dengan `GET` dan `POST`.
+
+---
+
+## 🔐 Authentication
+
+Semua request ke `/api/enroll` **wajib** menyertakan header:
+
+```
+Authorization: Bearer <token>
+```
+
+| Info        | Nilai        |
+|-------------|--------------|
+| Token default | `secret123` |
+| Letak config  | `app.py` → variabel `API_TOKEN` |
+
+**Response `401 Unauthorized`** (tanpa header)
+
+```json
+{
+  "error": "missing or invalid Authorization header"
+}
+```
+
+**Response `401 Unauthorized`** (token salah)
+
+```json
+{
+  "error": "invalid token"
+}
+```
+

+      "type": "Annually",
+      "service": "Pro",
+      "user": "alice"
+    }
+  ]
+}
+```
+
+---

+
+**Request**
+
+```
+GET /api/enroll?id=<id>
+Authorization: Bearer secret123
+```
+
+**Parameter Query**
+
+| Parameter | Tipe    | Wajib | Keterangan    |

+curl -H "Authorization: Bearer secret123" \
+  http://localhost:8080/api/enroll?id=1
+```
+
+**Response `200 OK`**
+

+  "data": {
+    "id": 1,
+    "type": "Annually",
+    "service": "Pro",
+    "user": "alice"
+  }
+}
+```
+
+**Response `404 Not Found`**
+
+```json
+{
+  "error": "not found"
+}
+```
+
+---
+
+## 3️⃣ Add — Menambah data baru
+
+**Request**
+
+```
+POST /api/enroll
+Authorization: Bearer secret123
+Content-Type: application/x-www-form-urlencoded
+```
+
+**Form Data**
+
+| Field     | Tipe   | Wajib | Keterangan                                              |
+|-----------|--------|-------|---------------------------------------------------------|
+| `type`    | string | ✅    | **Hanya boleh `Annually` atau `Monthly`**               |
+| `service` | string | ✅    | **Hanya boleh `Lite`, `Value`, atau `Pro`**             |
+| `user`    | string | ✅    | Nama pengguna                                           |
+
+> ⚠️ Jangan kirim field `id` — kalau `id` terkirim, ini akan dianggap **Edit**.
+
+**Contoh curl**
+
+```bash
+curl -X POST http://localhost:8080/api/enroll \
+  -H "Authorization: Bearer secret123" \
+  -d "type=Annually" \
+  -d "service=Pro" \
+  -d "user=alice"
+```
+
+**Response `201 Created`**
+
+```json
+{
+  "message": "created",
+  "id": 1
+}
+```
+
+**Response `400 Bad Request`** (type/service tidak valid)
+
+```json
+{
+  "error": "type must be one of: Annually, Monthly"
+}
+```
+
+```json
+{
+  "error": "service must be one of: Lite, Value, Pro"
+}
+```
+
+---
+
+## 4️⃣ Edit — Mengubah data yang sudah ada
+
+**Request**
+
+```
+POST /api/enroll
+Authorization: Bearer secret123
+Content-Type: application/x-www-form-urlencoded
+```
+
+**Form Data**
+
+| Field     | Tipe    | Wajib | Keterangan                                              |
+|-----------|---------|-------|---------------------------------------------------------|
+| `id`      | integer | ✅    | ID yang ingin diubah                                    |
+| `type`    | string  | ✅    | **Hanya boleh `Annually` atau `Monthly`** (baru)        |
+| `service` | string  | ✅    | **Hanya boleh `Lite`, `Value`, atau `Pro`** (baru)      |
+| `user`    | string  | ✅    | Nama pengguna (baru)                                    |
+
+> 💡 Cukup sertakan `id` pada form POST, sistem otomatis tahu ini adalah operasi **Edit**.
+
+**Contoh curl**
+
+```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"
+```
+
+**Response `200 OK`**
+
+```json
+{
+  "message": "updated",
+  "id": 1
+}
+```
+
+**Response `400 Bad Request`** (type/service tidak valid)
+
+```json
+{
+  "error": "type must be one of: Annually, Monthly"
+}
+```
+
+```json
+{
+  "error": "service must be one of: Lite, Value, Pro"
+}
+```
+
+---
+
+## 5️⃣ Remove — Menghapus data
+
+**Request**
+
+```
+POST /api/enroll
+Authorization: Bearer secret123
+Content-Type: application/x-www-form-urlencoded
+```
+
+**Form Data**
+
+| Field     | Tipe    | Wajib | Keterangan                                  |
+|-----------|---------|-------|---------------------------------------------|
+| `id`      | integer | ✅    | ID yang ingin dihapus                       |
+| `action`  | string  | ✅    | Harus bernilai `"remove"` (sebagai penanda) |
+
+**Contoh curl**
+
+```bash
+curl -X POST http://localhost:8080/api/enroll \
+  -H "Authorization: Bearer secret123" \
+  -d "id=1" \
+  -d "action=remove"
+```
+
+**Response `200 OK`**
+
+```json
+{
+  "message": "removed",
+  "id": 1
+}
+```
+
+**Response `400 Bad Request`** (tanpa id)
+
+```json
+{
+  "error": "id is required for remove"
+}
+```
+
+---
+
+## 📋 Ringkasan Logika POST
+
+```
+POST /api/enroll
+│
+├── action = "remove"  →  hapus data (butuh id)
+├── ada id             →  edit data (butuh type, service, user)
+└── tidak ada id       →  tambah data baru (butuh type, service, user)
+```
+
+## 🔑 Ringkasan Response Error
+
+| Status | Kondisi                        | Body                                        |
+|--------|--------------------------------|---------------------------------------------|
+| `401`  | Tanpa header Authorization     | `{"error": "missing or invalid …"}`         |
+| `401`  | Token salah                    | `{"error": "invalid token"}`                |
+| `400`  | Field wajib kosong             | `{"error": "… are required"}`               |
+| `400`  | Type bukan Annually/Monthly    | `{"error": "type must be one of: Annually, Monthly"}` |
+| `400`  | Service bukan Lite/Value/Pro   | `{"error": "service must be one of: Lite, Value, Pro"}` |
+| `404`  | ID tidak ditemukan             | `{"error": "not found"}`                    |
+
+## 🎮 Playground UI
+
+Setelah server jalan, buka browser ke:
+
+```
+http://localhost:8080
+```
+
+Anda akan diarahkan ke halaman **Playground** yang memudahkan pengujian semua endpoint langsung dari browser:
+
+1. **Isi token** di bar atas (default: `secret123`)
+2. Status otomatis berubah: ✅ authenticated / ❌ wrong token
+3. Isi form, klik tombol, lihat response JSON secara realtime
+
+---
+
+## 🚀 Quick Start
+
+```bash
+# masuk ke folder project
+cd api-playground
+
+# install dependency
+pip3 install -r requirements.txt
+
+# jalankan server
+python3 app.py
+
+# buka di browser
+# http://localhost:8080
+```
+
+Server akan berjalan di `http://0.0.0.0:8080` dengan `reloader=True` (auto-restart saat kode diubah).
