WAservix Laravel integration

Connect WAservix to your Laravel app: send WhatsApp messages from your own WhatsApp number, check delivery and receive replies by webhook. Copy the examples, add your key and run.

Requirements

Laravel 9+ (uses the built-in HTTP client, nothing to install).

Add your API key

Create a key under WAservix → Devices → API key (it starts with wpk_). Keep it on your server, in an environment variable or secret store. Never put it in a website, a mobile app or a public repository.

// .env
WASERVIX_KEY=wpk_your_key
WASERVIX_WEBHOOK_SECRET=your_webhook_secret

// config/services.php
'waservix' => [
    'key'            => env('WASERVIX_KEY'),
    'webhook_secret' => env('WASERVIX_WEBHOOK_SECRET'),
],

Set up the client

Base URL https://tekservix.com/waservix/api. Send the key as Authorization: Bearer wpk_….

use Illuminate\Support\Facades\Http;

Send a WhatsApp message

Messages are queued and sent one at a time per number, so the answer comes back at once with "status": "in_progress" and a msgId.

$response = Http::withToken(config('services.waservix.key'))
    ->timeout(30)
    ->post('https://tekservix.com/waservix/api/send-message', [
        'to' => '+250788123456',
        'text' => 'Hello Aline, your order is ready',
    ])
    ->throw();

$data = $response->json('data');

Send a document or image

Use imageUrl, videoUrl, audioUrl or documentUrl with a public https link. Groups work too: put the group JID (…@g.us) in to.

$response = Http::withToken(config('services.waservix.key'))
    ->timeout(30)
    ->post('https://tekservix.com/waservix/api/send-message', [
        'to' => '+250788123456',
        'text' => 'Your invoice',
        'documentUrl' => 'https://example.com/inv-1042.pdf',
        'fileName' => 'Invoice-1042.pdf',
    ])
    ->throw();

$data = $response->json('data');

Check message status

status is queued, sent, delivered, read, played or failed. Webhooks tell you without polling.

$response = Http::withToken(config('services.waservix.key'))
    ->timeout(30)
    ->get('https://tekservix.com/waservix/api/messages/58213/info')
    ->throw();

$data = $response->json('data');

Receive WhatsApp messages by webhook

Set a webhook URL and events for the number under WAservix → Devices. Each request carries X-Webhook-Signature, which equals that device’s webhook secret. Compare it in constant time, answer 2xx quickly and process the message after answering (we retry 3 times).

// app/Http/Controllers/WaservixWebhookController.php
namespace App\Http\Controllers;

use Illuminate\Http\Request;

class WaservixWebhookController extends Controller
{
    public function __invoke(Request $request)
    {
        abort_unless(hash_equals((string) config('services.wapenda.webhook_secret'), (string) $request->header('X-Webhook-Signature')), 401);

        $event = $request->json()->all();
        if ($event['event'] === 'messages.received') {
            $m = $event['data']['messages'];
            logger()->info('WhatsApp from ' . ($m['key']['cleanedSenderPn'] ?? ''), ['text' => $m['messageBody'] ?? '']);
        }
        return response()->noContent();
    }
}

// routes/api.php  (the api group has no CSRF check, so no exception is needed)
Route::post('/webhooks/wapenda', \App\Http\Controllers\WaservixWebhookController::class);

Errors, limits and retries

Every answer has success; errors add a readable message. 401 means a wrong key, 402 no active plan for this number or phone, 409 the number or phone isn’t connected, 429 too many requests (300 a minute per key): wait for the Retry-After seconds and try again. Retry 5xx and network errors with a back-off, but don’t blindly retry a send that may have worked: check its status first, or you could send twice.

Questions

Is this the official WhatsApp Business API?

No. WAservix links your own number as a companion device, like WhatsApp Web, so there is no Meta approval. Only message people who expect to hear from you: WhatsApp can ban numbers that spam.

Can I call the API from a mobile app or browser?

Don’t. Anyone could read the key from the app or page. Call the API from your server and let your app talk to your server.
