## Mula pantas

```html
<!-- 1. Load via CDN (or npm install captchala) -->
<script src="https://cdn.captcha-cdn.net/captchala-loader.js"></script>

<button id="login-btn">Sign in</button>

<script>
loadCaptchala(function () {
  Captchala.init({
    appKey: 'YOUR_APP_KEY',
    product: 'bind',
    action: 'login',
    lang: 'auto',
  })
  .onSuccess(res => sendToBackend(res.token))
  .onError(err => console.error(err.message))
  .bindTo('#login-btn');
});
</script>
```

## Pemasangan

### CDN

```html
<!-- Recommended: auto-fallback loader, ~6 KB gzip -->
<script src="https://cdn.captcha-cdn.net/captchala-loader.js"></script>
```

### NPM

```bash
npm install captchala
# or framework wrappers
npm install @captcha-la/vue
npm install @captcha-la/react
```

```js
import Captchala from 'captchala';
import 'captchala/dist/captchala.css';
```

## Mod

### Mod Popup

```js
Captchala.init({ appKey: 'YOUR_APP_KEY', product: 'popup', action: 'login' })
  .bindTo('#login-btn')
  .onSuccess(res => sendToBackend(res.token));
```

### Mod Float

```js
Captchala.init({ appKey: 'YOUR_APP_KEY', product: 'float', action: 'browse' })
  .appendTo('#captcha-container')
  .onSuccess(res => sendToBackend(res.token));
```

### Mod Bind

```js
Captchala.init({ appKey: 'YOUR_APP_KEY', product: 'bind', action: 'login' })
  .bindTo('#submit-button')
  .onSuccess(res => submitForm(res.token));   // fires only after challenge passes
```

### Mod Benam

```js
Captchala.init({ appKey: 'YOUR_APP_KEY', product: 'embed', action: 'register' })
  .appendTo('#captcha-container')
  .onSuccess(res => sendToBackend(res.token));
```

## Pilihan biasa

| Parameter | Jenis | Lalai | Penerangan |
| --- | --- | --- | --- |
| `appKey` | string | — | App Key (Diperlukan) |
| `product` | string | `popup` | Mod Paparan: popup | float | embed | bind |
| `action` | string | `default` | Senario Perniagaan |
| `lang` | string | `en` | Bahasa yang disokong: zh-CN / zh-TW / en / ja / ko / ms / vi / id |
| `serverToken` | string | — | Token sekali guna (sct_xxx) yang dikeluarkan oleh pelayan anda. Sangat disyorkan dalam persekitaran pengeluaran |
| `onServerTokenExpired` | `() => Promise<string>` | — | Dipanggil apabila serverToken tamat tempoh; pulangkan token baharu supaya SDK boleh meneruskan pengesahan |
| `enableVoice` | boolean | `true` | Sama ada memaparkan pilihan pengesahan audio (sokongan kebolehcapaian untuk pengguna cacat penglihatan) |

## Pengesahan sebelah pelayan

After `onSuccess`, send `res.token` (prefix `pt_`) to your own backend, then validate it server-side:

```bash
POST https://apiv1.captcha.la/v1/validate
X-App-Key: YOUR_APP_KEY
X-App-Secret: YOUR_APP_SECRET
Content-Type: application/json

{ "pass_token": "<token>" }
```
