Quick Start

use BlacklineCloud\SDK\GowaPHP\Client\AppClient;
use BlacklineCloud\SDK\GowaPHP\Client\SendClient;
use BlacklineCloud\SDK\GowaPHP\Config\ClientConfigBuilder;
use BlacklineCloud\SDK\GowaPHP\Http\ClientFactory;
use BlacklineCloud\SDK\GowaPHP\Support\NativeUuidGenerator;
use Nyholm\Psr7\Factory\Psr17Factory;
use Nyholm\Psr7\HttpClient\CurlClient;
use Psr\Log\NullLogger;

$config = ClientConfigBuilder::fromArray([
    'base_uri' => 'http://localhost:3000',
    'username' => 'admin',
    'password' => 'admin',
]);

$factory = new ClientFactory(
    requestFactory: $psr17 = new Psr17Factory(),
    streamFactory: $psr17,
    psr18: new CurlClient($psr17),
    logger: new NullLogger(),
    uuid: new NativeUuidGenerator(),
);

$app  = $factory->createAppClient($config);
$send = $factory->createSendClient($config);

// Login (QR)
$app->login();

// Send text
$send->text('[email protected]', 'Hello from PHP');
// Send chat presence
$send->chatPresence('[email protected]', \BlacklineCloud\SDK\GowaPHP\Domain\Enum\PresenceState::Composing);

Webhook Verification

See docs/notes/webhook-verification.md for signature verification, PSR-15 middleware example, and idempotency tips. In brief:

$raw = file_get_contents('php://input');
$sig = $_SERVER['HTTP_X_HUB_SIGNATURE_256'] ?? '';
$verifier = new \BlacklineCloud\SDK\GowaPHP\Webhook\WebhookVerifier('your-secret');
if (! $verifier->verify($raw, $sig)) {
    http_response_code(401);
    exit('invalid signature');
}
$event = (new \BlacklineCloud\SDK\GowaPHP\Webhook\WebhookEventHydrator())->hydrate(\BlacklineCloud\SDK\GowaPHP\Serialization\Json::decode($raw));

Supported PHP

PHP 8.2+ (tested on 8.2/8.3/8.4).

Contributing

• Run tests and static analysis: composer lint && composer stan && composer psalm && composer test.
• See CONTRIBUTING.md for the self-review checklist and upgrade workflow.

Releases

• Semantic versioning. Tags matching v* run CI, create a GitHub Release, and (optionally) ping Packagist if credentials are configured.
