README

The Cbox Engage client for Laravel. Three things, all against the workspace's ingest key:

• Product events in. ProductEvents::record() queues one event to Engage's POST /v1/events; nothing that goes wrong reaches the caller.
• Transactional messages out. Messages::send() and Messages::status() over POST /v1/messages and GET /v1/messages/{id}, with typed receipts and exceptions.
• The engage mail driver. MAIL_MAILER=engage sends every Mailable through Engage's send gate, with a circuit breaker and a fallback mailer for when Engage is down, so a password reset always leaves.

Documentation: docs/index.md. Start with the quickstart.

Install

composer require cboxdk/laravel-engage-client

Two environment keys, the same ones every Cbox app already uses:

ENGAGE_INGEST_URL=https://app.cboxengage.com
ENGAGE_INGEST_KEY=ek_…

With either empty, product events go nowhere, Messages throws EngageNotConfigured on use, and the engage mailer refuses to be built. Publish the config with php artisan vendor:publish --tag=engage-config for the rest (config/engage.php).

Product events

use Cbox\Engage\Contracts\ProductEvents;
use Cbox\Engage\Events\ProductEvent;

public function __construct(private ProductEvents $events) {}

$this->events->record(ProductEvent::byContact(
    name: 'project.created',
    eventId: "cbox-id:project.created:{$project->id}",   // deterministic: a retry is one event
    userExternalId: $user->cbox_id,
    companyExternalId: $organization->cbox_id,
    props: ['project_id' => $project->id],
));

Messages

use Cbox\Engage\Contracts\Messages;
use Cbox\Engage\Messages\{InlineContent, OutgoingMessage, Recipient};

$receipt = app(Messages::class)->send(new OutgoingMessage(
    idempotencyKey: "otp:{$user->id}:{$slot}",
    to: new Recipient(externalId: $user->cbox_id, email: $user->email),
    brand: 'br_01…',
    content: new InlineContent('Your code', "<p>{$code}</p>", $code),
));

$receipt->queued();          // or ->gatedOut() with ->reasons
app(Messages::class)->status($receipt->id)->latestEvent()?->status;   // 'delivered', 'bounced', …

The mail driver

// config/mail.php
'default' => env('MAIL_MAILER', 'engage'),
'mailers' => [
    'engage' => ['transport' => 'engage', 'fallback' => 'resend'],
    'resend' => ['transport' => 'resend'],
],

// A Mailable
use Cbox\Engage\Mail\EngageOptions;

class PasswordReset extends Mailable { use EngageOptions; /* … */ }

Mail::to($user)->send((new PasswordReset($token))->engage(externalId: $user->cbox_id, idempotencyKey: "reset:{$token->id}"));

When Engage is unavailable five times in a minute, the breaker opens for two minutes and mail goes straight through resend; one probe every two minutes brings Engage back. A suppressed address throws Cbox\Engage\Mail\MailRefused instead of being sent elsewhere.

Testing

use Cbox\Engage\Testing\InteractsWithEngage;   // in your TestCase

$engage = $this->fakeEngage();
$engage->assertRecorded('project.created', fn ($e) => $e->props['project_id'] === $project->id);
$engage->assertSent(fn ($m) => $m->idempotencyKey === "reset:{$token->id}");
