README

Distributed audit logging for Laravel microservices. The package publishes audit events from each service to RabbitMQ and includes helpers for Eloquent model auditing, manual audit logs, user context resolution, OpenTelemetry trace correlation, and fallback storage when publishing fails.

Requirements

PHP 8.4 or newer
Laravel 11, 12, or compatible 13.x release
RabbitMQ
Redis if you consume events with uzapoint/eventbus-core idempotency enabled
A central audit/log service with a table that can store consumed audit records

Installation

Install the package in every microservice that should publish audit events:

composer require uzapoint/auditable

The package depends on uzapoint/eventbus-core, which provides the RabbitMQ publisher and consumer command.

If Laravel package discovery is not available, register the service providers manually in config/app.php:

'providers' => [
    Uzapoint\EventBus\EventBusServiceProvider::class,
    Uzapoint\Auditable\AuditServiceProvider::class,
],

Configure RabbitMQ

AuditPublisher publishes to the RabbitMQ topic exchange audit.events with the routing key audit.events. The event bus reads RabbitMQ connection values from config('queue.connections.rabbitmq'), so add a RabbitMQ connection to config/queue.php in each publishing service:

'connections' => [
    // ...

    'rabbitmq' => [
        'host' => env('RABBITMQ_HOST', '127.0.0.1'),
        'port' => env('RABBITMQ_PORT', 5672),
        'user' => env('RABBITMQ_USER', 'guest'),
        'password' => env('RABBITMQ_PASSWORD', 'guest'),
        'vhost' => env('RABBITMQ_VHOST', '/'),
    ],
],

Add the matching environment variables:

RABBITMQ_HOST=127.0.0.1
RABBITMQ_PORT=5672
RABBITMQ_USER=guest
RABBITMQ_PASSWORD=guest
RABBITMQ_VHOST=/

Configure Auditing

The package merges config/auditable.php by default. To customize config and publish the fallback migration into an application, run:

php artisan vendor:publish --tag=auditable

This publishes:

config/auditable.php
database/migrations/2026_07_15_000001_create_failed_audit_events_table.php

You can also publish each asset type separately:

php artisan vendor:publish --tag=auditable-config
php artisan vendor:publish --tag=auditable-migrations

Set the service identity in .env. These values are added to every published audit payload so the central audit service can identify the source service.

AUDIT_SERVICE_NAME=inventory-service
AUDIT_SERVICE_ENV=production
AUDIT_FALLBACK_ENABLED=true
AUDIT_FALLBACK_TABLE=failed_audit_events
AUDIT_FALLBACK_RETRY_AFTER=5

Important config values:

return [
    'service' => [
        'name' => env('AUDIT_SERVICE_NAME', config('app.name')),
        'environment' => env('AUDIT_SERVICE_ENV', config('app.env')),
    ],

    'events' => [
        'created',
        'updated',
        'deleted',
        'voided',
        'approved',
        'rejected',
        'restored',
    ],

    'sensitive_fields' => [
        'password',
        'password_confirmation',
        'token',
        'api_token',
        'secret',
        'credit_card',
        'cvv',
        'ssn',
    ],
];

Use events => ['*'] to publish every supported event. Sensitive fields are recursively replaced with ***REDACTED*** inside changes and properties.

Enable Model Auditing

Add the Auditable trait to any Eloquent model that should publish audit events.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Uzapoint\Auditable\Traits\Auditable;

class Order extends Model
{
    use Auditable;
    use SoftDeletes;

    protected $fillable = [
        'customer_id',
        'status',
        'total',
        'void_reason',
        'rejection_reason',
    ];
}

The trait publishes:

created when a model is created
updated when persisted attributes change
deleted when a model is deleted
restored for models using soft deletes
voided when status changes to voided
approved when status changes from pending to approved or completed
rejected when status changes from pending to rejected

Each event includes the subject type, subject id, causer context, old/new changes, service metadata, host, timestamp, optional batch UUID, and current OpenTelemetry trace/span ids.

Manual Audit Logs

Use the facade when you need to audit an action that is not tied directly to an Eloquent lifecycle event:

use Uzapoint\Auditable\Facades\Audit;

Audit::log('invoice.sent', 'Invoice #123 was sent to the customer', [
    'log_name' => 'invoices',
    'subject_type' => App\Models\Invoice::class,
    'subject_id' => 123,
    'causer_id' => auth('api')->id(),
    'causer_type' => App\Models\User::class,
    'causer_name' => optional(auth('api')->user())->name,
    'causer_email' => optional(auth('api')->user())->email,
    'changes' => null,
    'properties' => [
        'channel' => 'email',
    ],
]);

You can also inject Uzapoint\Auditable\Services\AuditPublisher and call publish(array $payload) directly when you already have the full audit payload.

User Context

UserContextResolver resolves the causer in this order:

Gateway headers and request input
Request body values
Context set for a queued job or consumed message
auth('api')->user()
A system context

For HTTP requests through an API gateway, pass these values when available:

X-Person-ID: 42
X-Business-ID: 1001
X-Person: base64-encoded JSON person object
X-User-Permissions: base64-encoded JSON permissions array
X-User-Roles: base64-encoded JSON roles array

The resolver also reads user_id, person, terminal_id, and terminal_information from the request body.

For queued jobs or message handlers, set the user context before changing audited models:

use Uzapoint\Auditable\Context\UserContextResolver;

UserContextResolver::set($message['user_context']);

try {
    $order->update(['status' => 'approved']);
} finally {
    UserContextResolver::clear();
}

To pass context into a new message, include:

'user_context' => UserContextResolver::forMessage(),

Batch Correlation

Use BatchContext when a workflow changes several models and you want all audit events to share a single batch id:

use Uzapoint\Auditable\Context\BatchContext;

$batchUuid = BatchContext::set();

try {
    $invoice->update(['status' => 'paid']);
    $payment->update(['status' => 'reconciled']);
} finally {
    BatchContext::clear();
}

The batch UUID is added to meta.batch_uuid on every audit payload published while the context is active.

Fallback Storage

When RabbitMQ publishing fails, the publisher can insert the payload into a local fallback table for retry. Publish the migration and run migrations:

php artisan vendor:publish --tag=auditable-migrations
php artisan migrate

The table defaults to failed_audit_events and stores the JSON payload, failure time, retry time, attempts, processed time, and error text.

Central Audit Service Consumer

In the central audit service, consume the audit.events exchange and route messages to ProcessAuditEvents.

Publish the event bus config:

php artisan vendor:publish --tag=eventbus-config

Configure config/eventbus.php:

use Uzapoint\Auditable\Jobs\ProcessAuditEvents;

return [
    'exchanges' => [
        'audit.events',
    ],

    'queues' => [
        [
            'name' => 'audit_service.audit_events',
            'exchange' => 'audit.events',
            'routing_keys' => [
                'audit.events',
            ],
        ],
    ],

    'handlers' => [
        'audit.events' => ProcessAuditEvents::class,
    ],

    'dead_letter' => [
        'enabled' => true,
        'ttl' => 86400000,
        'max_retries' => 3,
        'exchange_prefix' => 'dlx.',
    ],
];

Run the consumer:

php artisan eventbus:consume --queue=audit_service.audit_events

ProcessAuditEvents inserts records into config('auditable.table', 'activity_logs'). Make sure the central audit service has a compatible activity_logs table or set auditable.table to the table name you want to use.

The expected columns are:

uuid
event
description
log_name
subject_type
subject_id
causer_type
causer_id
causer_name
causer_email
changes
properties
source_service
source_environment
source_host
batch_uuid
created_at
recorded_at

Typical Microservice Setup Checklist

Install uzapoint/auditable.
Add the RabbitMQ connection to config/queue.php.
Set AUDIT_SERVICE_NAME, AUDIT_SERVICE_ENV, and RabbitMQ environment variables.
Run php artisan vendor:publish --tag=auditable to publish package config and fallback migration.
Run php artisan migrate if local failed-publish storage is required.
Add Uzapoint\Auditable\Traits\Auditable to each model that should publish audit events.
Forward gateway user headers or set UserContextResolver in queued/message workflows.
Run the central audit service consumer for the audit.events queue.

Troubleshooting

If no events reach the audit service, verify RabbitMQ credentials in config('queue.connections.rabbitmq') and confirm the central service is consuming audit.events.
If audit records have source_service=unknown, set AUDIT_SERVICE_NAME in the publishing service.
If causer fields are empty, forward the gateway headers or set UserContextResolver before updating audited models.
If sensitive data appears in payloads, add the exact field names to auditable.sensitive_fields.
If consumed events are ignored, confirm config/eventbus.php maps the audit.events routing key to Uzapoint\Auditable\Jobs\ProcessAuditEvents::class.
