Runtime Client Architecture

SDK menggunakan runtime token architecture.

Contoh:

use Sejator\WabaSdk\Services\Client;
use Sejator\WabaSdk\Services\MessageService;

$client = app(Client::class)
    ->withToken($device->access_token);

$messageService = new MessageService(
    $client
);

---

Send Text Message

$response = $messageService->text(
    phoneNumberId: $device->phone_number_id,
    to: '628xxxx',
    text: 'Hello World'
);

---

Send Media Message

Image

$response = $messageService->media(
    phoneNumberId: $device->phone_number_id,
    to: '628xxxx',
    type: 'image',
    url: 'https://example.com/image.jpg',
    caption: 'Image Caption'
);

---

Document

$response = $messageService->media(
    phoneNumberId: $device->phone_number_id,
    to: '628xxxx',
    type: 'document',
    url: 'https://example.com/file.pdf',
    caption: 'Invoice',
    filename: 'invoice.pdf'
);

---

Send Template Message

$response = $messageService->template(
    $device->phone_number_id,
    [
        'to' => '628xxxx',
        'template' => [
            'name' => 'hello_world',
            'language' => [
                'code' => 'id'
            ],
        ],
    ]
);

---

Media Service

Upload Media

use Sejator\WabaSdk\Services\MediaService;

$media = new MediaService($client);

$response = $media->upload(
    $device->phone_number_id,
    storage_path('app/image.jpg')
);

---

Download Media

$binary = $media->download($mediaUrl);

---

Template Service

Get Templates

use Sejator\WabaSdk\Services\TemplateService;

$templates = $service->all(
    $device->waba_id
);

---

Create Template

$response = $service->create(
    $device->waba_id,
    [
        'name' => 'promo_template',
        'language' => 'id',
        'category' => 'MARKETING',
        'components' => [
            [
                'type' => 'BODY',
                'text' => 'Halo {{1}}'
            ]
        ],
    ]
);

---

Embedded Signup

Generate Signup URL

use Sejator\WabaSdk\Services\EmbeddedSignupService;
use Sejator\WabaSdk\Support\Embedded\OAuthCallbackHandler;

$handler = app(
    OAuthCallbackHandler::class
);

$session = $handler->createSession([
    'context' => [
        'tenant_id' => tenant()->id,
        'user_id' => auth()->id(),
    ],
]);

$embedded = app(
    EmbeddedSignupService::class
);

$signup = $embedded->signupUrl(
    $session->state
);

$url = $signup['url'];

---

Open Embedded Signup Popup

window.open(url, "metaEmbeddedSignup", "width=560,height=820");

---

OAuth Callback Example

$result = $handler->handle(
    code: request('code'),
    state: request('state')
);

$accessToken = $result->accessToken;

---

Error Handling

use Sejator\WabaSdk\Exceptions\GraphApiException;

try {

    // SDK Call

} catch (GraphApiException $e) {

    logger()->error(
        $e->toArray()
    );

}

---

Multi Tenant Example

$client = app(Client::class)
    ->withToken(
        $device->access_token
    );

$messageService = new MessageService(
    $client
);

---

Production Notes

Embedded Signup Callback

Disarankan callback route:

• tidak memakai auth middleware
• tidak bergantung session Laravel
• menggunakan OAuth state context
• menggunakan HTTPS

---

Media URL

WhatsApp Cloud API mewajibkan:

• HTTPS public URL
• publicly accessible media
• valid mime type
