README

Official PHP SDK for the OpenWA WhatsApp API Gateway.

A synchronous client built on Guzzle, PSR-4 autoloaded.

Install

Not yet published to Packagist. Until the first release, install from a checkout of the repo (cd sdk/php && composer install) or point Composer at the repository directly.

composer require rmyndharis/openwa   # once published

Requires PHP 8.1+ and Guzzle 7. The namespace is OpenWA\.

Usage

<?php
require 'vendor/autoload.php';

use OpenWA\Client;

$client = new Client([
    'baseUrl' => 'https://your-gateway.example.com',
    'apiKey'  => 'owa_k1_…',
]);

$client->sessions->start('my-session');

$result = $client->messages->sendText('my-session', [
    'chatId' => '628123456789@c.us',
    'text'   => 'Hello from the OpenWA PHP SDK!',
]);
echo $result['messageId'];

For tests, inject a Guzzle client whose handler is a MockHandler — no network, no global state:

$client = new Client([
    'baseUrl'    => 'http://x',
    'apiKey'     => 'k',
    'httpClient' => $mockGuzzleClient,
]);

Errors

A non-2xx response throws a typed OpenWA\Exceptions\OpenWAApiException subclass — OpenWAAuthException (401), OpenWAForbiddenException (403), OpenWANotFoundException (404), OpenWAConflictException (409), OpenWARateLimitException (429), OpenWANotImplementedException (501) — each exposing getStatus() and the parsed getBody(). A timeout throws OpenWATimeoutException.

use OpenWA\Exceptions\OpenWANotFoundException;

try {
    $client->sessions->get('missing');
} catch (OpenWANotFoundException $e) {
    echo $e->getStatus();  // 404
}

Notes

• Use HTTPS in production — the API key is sent as X-API-Key and is bearer-equivalent.
• The SDK does not retry, and never follows redirects (so the key is never re-sent to a redirect target). Path segments are percent-encoded; a base-URL path prefix (e.g. behind a reverse proxy) is preserved.
• Escape hatch for endpoints the SDK does not wrap: $client->request($method, $path, $query, $body).
