README

Facebook Messenger adapter for the laravel-bootdesk multi-platform messaging framework.

Install

composer require bootdesk/chat-sdk-adapter-messenger

Requires a PSR-18 HTTP client (guzzlehttp/guzzle, symfony/http-client, etc.) and a PSR-17 factory (nyholm/psr7 bundled).

Configuration

Variable	Description	Example
`page_access_token`	Facebook Page Access Token	`EAAx...`
`http_client`	PSR-18 HTTP client instance	`new GuzzleHttp\Client`
`app_secret`	Facebook App Secret	`abc123...`
`verify_token`	Webhook Verify Token	`my-verify-token`

use BootDesk\ChatSDK\Messenger\MessengerAdapter;

$adapter = new MessengerAdapter(
    pageAccessToken: env('MESSENGER_PAGE_ACCESS_TOKEN'),
    httpClient: new \GuzzleHttp\Client,
    appSecret: env('MESSENGER_APP_SECRET'),
    verifyToken: env('MESSENGER_VERIFY_TOKEN'),
);

Laravel

The ChatServiceProvider auto-binds Psr\Http\Client\ClientInterface to GuzzleHttp\Client. Add to config/chat.php:

'messenger' => [
    'page_access_token' => env('MESSENGER_PAGE_ACCESS_TOKEN'),
    'app_secret'        => env('MESSENGER_APP_SECRET'),
    'verify_token'      => env('MESSENGER_VERIFY_TOKEN'),
],

Quick Example

// Send a message to a user
$adapter->postMessage('messenger:1234567890', 'Hello from laravel-bootdesk!');

Message Templates

Messenger supports rich message templates via PostableMessage::template() with MessengerTemplate:

use BootDesk\ChatSDK\Messenger\MessengerTemplate;

// Button template
$adapter->postMessage('messenger:1234567890', PostableMessage::template(
    MessengerTemplate::create('options')
        ->buttonTemplate('Choose an option', [
            ['type' => 'postback', 'title' => 'Yes', 'payload' => 'YES'],
            ['type' => 'postback', 'title' => 'No', 'payload' => 'NO'],
        ])
));

// Generic template (carousel)
$adapter->postMessage('messenger:1234567890', PostableMessage::template(
    MessengerTemplate::create('catalog')
        ->genericTemplate([
            [
                'title' => 'Product A',
                'subtitle' => 'Best seller',
                'image_url' => 'https://example.com/a.jpg',
                'default_action' => ['type' => 'web_url', 'url' => 'https://example.com/a'],
                'buttons' => [['type' => 'web_url', 'title' => 'Buy', 'url' => 'https://example.com/a/buy']],
            ],
        ])
));

// Media template
$adapter->postMessage('messenger:1234567890', PostableMessage::template(
    MessengerTemplate::create('intro')
        ->mediaTemplate('https://example.com/video.mp4', 'video', [
            'type' => 'web_url', 'title' => 'Learn More', 'url' => 'https://example.com',
