Laravel ZATCA (Fatoora) Package

Saudi Arabian e-Invoicing Compliance — Phase 1 & Phase 2

المرحلة الأولى والثانية للفاتورة الإلكترونية السعودية لهيئة الزكاة والضريبة والجمارك

By AL-AGHBARI Fatehi — فتحي الأغبري

ZATCA integration for Laravel — QR code generation, TLV encoding, invoice signing, clearance & reporting. دمج الفاتورة الإلكترونية مع لارافيل: المرحلة الأولى (QR) والمرحلة الثانية (التوقيع والإرسال) لهيئة الزكاة والضريبة والجمارك السعودية

Overview

laravel-zatca is a production-grade Laravel package for integrating with the ZATCA (Zakat, Tax and Customs Authority) e-invoicing system — also known as Fatoora — in the Kingdom of Saudi Arabia.

The package covers both phases of the ZATCA e-invoicing mandate:

Phase	Description	Status
Phase 1	Generate and display QR code on invoices (TLV Base64 format)	Production Ready
Phase 2	Full compliance: CSR, Certificate, Signing, Clearance & Reporting via FATOORA API	Production Ready

Flexible Integration

You can use this package in any of these modes:

Phase 1 only — Just generate QR codes for display on PDF/View (no API calls)
Phase 2 only — Full API integration (requires pre-existing Phase 1 QR or external QR generation)
Both phases — Full lifecycle from QR → Signing → Submission
Offline → Online — Generate QR codes offline, sync invoices via queue when online

What is Required vs Optional

For Phase 1 (QR generation only):

Step	Required?
Install package (`composer require`)	Required
Set `ZATCA_PHASE` and `ZATCA_VAT_*` in `.env`	Required
Call `Zatca::phase1()->generateQrCodeText()` in your controller	Required
Display QR in your Blade view	Required
Publish config / views	Optional
Install `simplesoftwareio/simple-qrcode` or `endroid/qr-code` for ZATCA-compatible QR	Optional but recommended
Use Model Trait for automatic QR generation	Optional
API Routes (`/zatca/onboard`, etc.)	Optional — not needed
Offline Mode & Queue Sync	Optional — not needed
Events & Logging	Optional — not needed

For Phase 2 (API integration):

Step	Required?
Everything from Phase 1	Required (if using `both`)
Set `ZATCA_PHASE=phase_2` or `=both`	Required
Complete onboarding (keys + CSR + certificate)	Required
Set `ZATCA_CERTIFICATE`, `ZATCA_PRIVATE_KEY`, `ZATCA_SECRET`	Required
Call `Zatca::phase2()->signInvoice()` + `->submitInvoice()`	Required
Publish migrations for audit logging	Optional
Use Queue for async sync	Optional
API Routes (`/zatca/onboard`)	Optional — alternative to CLI
Events & custom listeners	Optional

Features

Phase 2: UBL 2.1 XML invoice building & XAdES signing
Phase 2: ECDSA secp256k1 key pair generation (OpenSSL)
Phase 2: CSR generation for ZATCA compliance certificate
Phase 2: Compliance check (Sandbox)
Phase 2: Clearance & Reporting (Production)
cURL-based HTTP client (no Guzzle dependency)
Queue support for async invoice sync with retry logic
Offline mode -- Generate signed XML locally, sync later
Artisan commands for onboarding & syncing
Event-driven architecture (InvoiceCleared, InvoiceReported, InvoiceFailed)
PSR-4 autoloading, Service Provider auto-discovery
Logging with PII masking, non-blocking design
No UI/frontend assumptions -- Bring your own views

Version Matrix

Component	Version
PHP	`^8.1`, `^8.2`, `^8.3`, `^8.4`
Laravel	`^9.0`, `^10.0`, `^11.0`, `^12.0`, `^13.0`
ZATCA API	V2 (2024+)
UBL Standard	2.1
Signature Algorithm	ECDSA secp256k1 + SHA-256
XAdES	EPES v1.3.2
QR Encoding	TLV Base64 (GS1-compatible)
OpenSSL	Required (for key & CSR generation)
cURL	Required extension

Optional QR Dependencies

The built-in QR generator (SvgQrGenerator) produces visual-only output that is not compatible with the official ZATCA (Fatoora) app. For production use, you must install one of these:

Package	Purpose	Install
`simplesoftwareio/simple-qrcode`	✅ ZATCA-compatible SVG QR	`composer require simplesoftwareio/simple-qrcode`
`endroid/qr-code`	✅ ZATCA-compatible QR (SVG/PNG)	`composer require endroid/qr-code`

If one of these is installed, the Blade view uses it automatically. If neither is installed, the built-in fallback produces a QR image that will not be readable by the ZATCA app.

Installation

composer require aghfatehi/laravel-zatca

That's it for Phase 1 — TLV generation works immediately. For QR rendering, you must install simplesoftwareio/simple-qrcode or endroid/qr-code (see Optional QR Dependencies). For Phase 2 you also need OpenSSL installed on your server and a ZATCA developer account.

Publish Configuration

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

Publish Migrations (Optional — for Phase 2 API & audit logging)

Publish and run the migrations only if you are using the optional Phase 2 API routes (onboarding, invoice clearance/reporting):

php artisan vendor:publish --tag=zatca-migrations
php artisan migrate --path=/database/migrations/2024_01_01_000001_create_zatca_certificates_table.php
php artisan migrate --path=/database/migrations/2024_01_01_000002_create_zatca_invoice_logs_table.php

This creates two tables:

Table	Purpose
`zatca_certificates`	Stores EGS certificate and private key after ZATCA onboarding (used for invoice signing)
`zatca_invoice_logs`	Logs every invoice submission request/response with `invoice_serial_number` for clearance & reporting audit trail

You do not need these migrations if you only use Phase 1 (QR code generation).

Publish Views (Optional — to customize QR fallback)

php artisan vendor:publish --tag=zatca-views

Copies qr-code.blade.php to resources/views/vendor/zatca/ so you can customize the default SVG layout.

Note: This view auto-detects simplesoftwareio/simple-qrcode, endroid/qr-code, and falls back to the built-in generator. Publish only if you need to customize the template.

Verify Installation

php artisan zatca:check

Configuration

Set these in your .env file:

# --- Phase Selection ---
ZATCA_PHASE=both                   # phase_1, phase_2, both

# --- Environment ---
ZATCA_ENVIRONMENT=sandbox          # sandbox | production

`ZATCA_CERTIFICATE`	Phase 2	Base64-encoded compliance certificate from ZATCA	ZATCA Developer Portal → after running `zatca:onboard` with OTP. The certificate is the `binarySecurityToken` returned by the compliance API.
`ZATCA_PRIVATE_KEY`	Phase 2	Base64-encoded EC private key (secp256k1)	Generated by you via `zatca:onboard` or `Zatca::phase2()->generateKeysAndCsr()`. Store securely — this is your secret key for signing invoices.
`ZATCA_SECRET`	Phase 2	Secret string returned by ZATCA during onboarding	ZATCA Developer Portal → returned alongside the certificate when you issue a compliance certificate with OTP.

How the onboarding flow works

1. You run:  php artisan zatca:onboard --otp=123456 --save
2. Package generates EC key pair (private_key + public_key)
3. Package creates a CSR (Certificate Signing Request)
4. Package sends CSR + OTP to ZATCA API
5. ZATCA returns:
   - binarySecurityToken → save as ZATCA_CERTIFICATE
   - secret              → save as ZATCA_SECRET
6. Your private_key      → save as ZATCA_PRIVATE_KEY

The OTP is obtained from the ZATCA Developer Portal (sandbox) or ZATCA production portal.

See config/zatca.php for all available options with documentation.

Phase 1 -- QR Code Generation (Basic Compliance)

Phase 1 requires no API calls. It generates a TLV-encoded Base64 QR string containing:

Tag	Field	Example
1	Seller Name	`شركة التقنية`
2	VAT Number	`300000000000003`
3	Date/Time (ISO 8601)	`2024-01-01T12:00:00Z`
4	Invoice Total (SAR)	`115.00`
5	VAT Total (SAR)	`15.00`

Usage

use Aghfatehi\Zatca\Facades\Zatca;

// Simple QR text generation
$qrText = Zatca::phase1()->generateQrCodeText(
    sellerName: 'شركة التقنية',
    vatNumber: '300000000000003',
    invoiceDate: '2024-01-01T12:00:00Z',
    totalAmount: '115.00',
    taxAmount: '15.00',
);

// Base64-encoded TLV string ready for embedding
echo $qrText;

Using with Invoice DTO

use Aghfatehi\Zatca\DTO\InvoiceDTO;

$invoice = InvoiceDTO::fromArray([
    'invoice_serial_number' => 'INV-001',
    'issue_date' => '2024-01-01',
    'issue_time' => '12:00:00',
    'line_items' => [
        [
            'id' => '1',
            'name' => 'Product A',
            'quantity' => 2,
            'tax_exclusive_price' => 100.00,
            'vat_percent' => 0.15,
        ],
    ],
]);

$egsUnit = [
    'vat_name' => 'شركة التقنية',
    'vat_number' => '300000000000003',
];

$qrText = Zatca::phase1()->generateQrCodeFromInvoice($invoice, $egsUnit);

Phase 2 -- FATOORA API Integration (Full Compliance)

Phase 2 requires completing the ZATCA onboarding process to obtain a compliance certificate, then signing and submitting invoices.

Step 1: Onboarding (One-time setup)

Generate EC key pair, CSR, and get compliance certificate from ZATCA:

php artisan zatca:onboard --otp=123456 --solution-name=ERP --save

Or programmatically:

// Generate keys & CSR
$keys = Zatca::phase2()->generateKeysAndCsr($egsUnit, 'ERP');

// Issue compliance certificate with OTP from ZATCA portal
$result = Zatca::phase2()->issueComplianceCertificate($keys['csr'], $otp);

if ($result->success) {
    // Save these securely
    $certificate = $result->binarySecurityToken;
    $secret = $result->secret;
    $privateKey = $keys['private_key'];
    
    // Store in .env or database
    \Illuminate\Support\Facades\Env::set('ZATCA_CERTIFICATE', base64_encode($certificate));
    \Illuminate\Support\Facades\Env::set('ZATCA_SECRET', $secret);
    \Illuminate\Support\Facades\Env::set('ZATCA_PRIVATE_KEY', base64_encode($privateKey));
}

Step 2: Sign & Submit Invoice

// Build invoice data
$invoice = InvoiceDTO::fromArray([
    'invoice_serial_number' => 'EGS1-886431145-1',
    'invoice_counter_number' => 2,
    'issue_date' => '2024-01-01',
    'issue_time' => '14:40:40',
    'previous_invoice_hash' => '',
    'line_items' => [
        [
            'id' => '1',
            'name' => 'Product A',
            'quantity' => 10,
            'tax_exclusive_price' => 100.00,
            'vat_percent' => 0.15,
        ],
    ],
]);

$egsUnit = [
    'uuid' => '6f4d20e0-6bfe-4a80-9389-7dabe6620f12',
    'custom_id' => 'EGS1-886431145',
    'model' => 'Desktop',
    'vat_number' => '300000000000003',
    'vat_name' => 'شركة التقنية',
    'crn_number' => '454634645645654',
    'location' => [
        'city' => 'Riyadh',
        'city_subdivision' => 'West',
        'street' => 'King Fahd Road',
        'building' => '1234',
        'plot_identification' => '0000',
        'postal_zone' => '11564',
    ],
    'branch_name' => 'Main Branch',
    'branch_industry' => 'Retail',
];

// 1. Sign invoice (generates XML + hash + QR)
$signed = Zatca::phase2()->signInvoice(
    invoice: $invoice,
    egsUnit: $egsUnit,
    certificate: $certificate,
    privateKey: $privateKey,
);

// 2. Submit to ZATCA (auto-detects sandbox vs production)
$result = Zatca::phase2()->submitInvoice(
    signedInvoiceXml: $signed['signed_xml'],
    invoiceHash: $signed['invoice_hash'],
    certificate: $certificate,
    secret: $secret,
);

if ($result->success) {
    echo 'Invoice submitted successfully! Request ID: ' . $result->requestID;
}

Using Queue for Async Sync

use Aghfatehi\Zatca\Jobs\SyncInvoiceToZatcaJob;

SyncInvoiceToZatcaJob::dispatch(
    invoiceData: $invoice->toArray(),
    egsUnit: $egsUnit,
    certificate: $certificate,
    privateKey: $privateKey,
    secret: $secret,
);

QR Code Display on PDF / View

Method 1: Blade View (Direct Rendering)

1. In the Controller — generate QR TLV:

<?php

namespace App\Http\Controllers;

use Aghfatehi\Zatca\Facades\Zatca;

class InvoiceController extends Controller
{
    public function show(Invoice $invoice)
    {
        $qrTlv = Zatca::phase1()->generateQrCodeFromInvoice(
            invoice: $invoice->toInvoiceDto(),
            egsUnit: [
                'vat_name' => config('zatca.egs.vat_name'),
                'vat_number' => config('zatca.egs.vat_number'),
            ],
        );

        return view('invoice.show', compact('invoice', 'qrTlv'));
    }
}

2. In the Blade file — render the QR:

{{-- resources/views/invoice/show.blade.php --}}
@extends('layouts.app')

@section('content')
    <div class="invoice">
        <h1>invoice No: {{ $invoice->number }}</h1>

        <table>
            @foreach ($invoice->items as $item)
                <tr>
                    <td>{{ $item->name }}</td>
                    <td>{{ $item->price }}</td>
                </tr>
            @endforeach
        </table>

        {{-- QR Code output — PNG (with endroid/qr-code) or SVG (fallback, not ZATCA-compatible) --}}
        <div class="qr-section" style="text-align: center; margin-top: 20px;">
            <img src="data:image/png;base64,{{ base64_encode(Zatca::qr()->render($qrTlv, 200)) }}"
                 alt="ZATCA QR Code"
                 style="width: 200px; height: 200px;">
        </div>
    </div>
@endsection

How it works: render() auto-detects installed packages in this order:

simplesoftwareio/simple-qrcode → SVG (ZATCA-compatible)
endroid/qr-code → PNG (ZATCA-compatible)
Built-in SvgQrGenerator → SVG (visual-only, not ZATCA-compatible)

Note: This is the same priority as the built-in Blade view. Install either simplesoftwareio/simple-qrcode or endroid/qr-code for production use.

Method 2: Using the Built-in Blade View

The package ships with a qr-code.blade.php view under the zatca:: namespace. It auto-detects the available QR library:

Priority	Library	Output	ZATCA Compatible	How to install
1st	`simplesoftwareio/simple-qrcode`	SVG	✅ Yes	`composer require simplesoftwareio/simple-qrcode`
2nd	`endroid/qr-code`	SVG	✅ Yes	`composer require endroid/qr-code`
3rd	Built-in `SvgQrGenerator` (fallback)	SVG	❌ No	Not needed (but avoid for production)

⚠️ Important: The built-in SvgQrGenerator is a visual-only fallback for development previews. It does not produce QR codes that the official ZATCA (Fatoora) app can scan. You must install one of the recommended packages (simplesoftwareio/simple-qrcode or endroid/qr-code) for ZATCA-compliant QR codes.

View variables:

Variable	Type	Default	Description
`$qrData`	string	required	TLV-encoded QR text from `generateQrCodeText()`
`$size`	int	200	Width/height of the QR code in pixels

Example:

{{-- Pass TLV data from controller --}}
@include('zatca::qr-code', ['qrData' => $qrTlv, 'size' => 200])

Full controller + view example:

use Zatca;

class InvoiceController extends Controller
{
    public function show(Invoice $invoice)
    {
        $qrTlv = Zatca::phase1()->generateQrCodeText(
            sellerName: config('zatca.egs.vat_name'),
            vatNumber: config('zatca.egs.vat_number'),
            invoiceDate: $invoice->created_at->format('Y-m-d\TH:i:s\Z'),
            totalAmount: (string)$invoice->total,
            taxAmount: (string)$invoice->tax,
        );

        return view('invoice.show', compact('invoice', 'qrTlv'));
    }
}

{{-- resources/views/invoice/show.blade.php --}}
@extends('layouts.app')

@section('content')
    <div class="invoice">
        <h1>Invoice #{{ $invoice->number }}</h1>
        {{-- ... invoice details ... --}}

        <div class="qr-section" style="text-align: center; margin-top: 20px;">
            @include('zatca::qr-code', ['qrData' => $qrTlv, 'size' => 200])
        </div>
    </div>
@endsection

Note: This view is always available (no vendor:publish required). Run php artisan vendor:publish --tag=zatca-views only if you need to customize the blade template.

Phase 2 QR Code (9 Tags)

Phase 1 QR contains 5 tags (seller name, VAT, date, total, tax). When scanned with the ZATCA (Fatoora) app, it displays a notice: "This code is not compatible with Phase 2" — this is normal for Phase 1 QR.

For full Phase 2 compliance, the QR must contain 9 tags including the invoice hash and digital signature. Generate it after signing the invoice:

$qrData = Zatca::generatePhase2Qr(
    sellerName: config('zatca.egs.vat_name'),
    vatNumber: config('zatca.egs.vat_number'),
    invoiceDate: $invoice->created_at->format('Y-m-d\TH:i:s\Z'),
    totalAmount: '115.00',
    taxAmount: '15.00',
    invoiceHash: $signedInvoice['invoice_hash'],          // from InvoiceSignerService
    digitalSignature: $signedInvoice['digital_signature'], // ECDSA signature
    publicKey: $signedInvoice['public_key'],               // from certificate
    certificateSignature: $signedInvoice['certificate_signature'], // from ZATCA
);

Then pass it to the same view:

@include('zatca::qr-code', ['qrData' => $qrData, 'size' => 200])

The 9 tags in a Phase 2 QR:

Tag	Field	Source
1	Seller Name	Config
2	VAT Number	Config
3	Timestamp	Invoice date
4	Invoice Total	Invoice
5	Total VAT	Invoice
6	Invoice Hash	SHA-256 of signed XML
7	Digital Signature	ECDSA signature
8	Public Key	EC certificate
9	Certificate Signature	ZATCA certificate

Method 3: Using the Model Trait

Add the trait to your invoice model:

use Aghfatehi\Zatca\Traits\HasZatcaQrCode;

class Invoice extends Model
{
    use HasZatcaQrCode;

    // Customize field names (optional)
    protected $zatcaSellerField = 'company_name';
    protected $zatcaVatField = 'vat_number';
    protected $zatcaDateField = 'invoice_date';
    protected $zatcaTotalField = 'total_amount';
    protected $zatcaTaxField = 'tax_amount';
}

Then in your view:

{{-- Automatically generates QR from model fields --}}
{!! $invoice->getZatcaQrCode(200) !!}

Method 4: PDF Generation with barryvdh/laravel-dompdf

use Barryvdh\DomPDF\Facade\Pdf;

$qrText = Zatca::phase1()->generateQrCodeText(
    sellerName: $invoice->company_name,
    vatNumber: $invoice->vat_number,
    invoiceDate: $invoice->invoice_date->format('Y-m-d\TH:i:s\Z'),
    totalAmount: (string)$invoice->total_amount,
    taxAmount: (string)$invoice->tax_amount,
);

// Generate QR as data URI (auto-detects format)
$qrDataUri = Zatca::qr()->renderAsDataUri($qrText, 150);

$pdf = Pdf::loadView('invoice.pdf', compact('invoice', 'qrDataUri'));
return $pdf->download('invoice.pdf');

In invoice/pdf.blade.php:

<html>
<head>
    <style>
        .qr-code { position: fixed; bottom: 20px; right: 20px; width: 150px; }
    </style>
</head>
<body>
    <h1>{{ $invoice->invoice_serial_number }}</h1>
    <table>
        <tr><th>Item</th><th>Price</th><th>VAT</th></tr>
        @foreach($invoice->items as $item)
        <tr><td>{{ $item->name }}</td><td>{{ $item->price }}</td><td>{{ $item->vat }}</td></tr>
        @endforeach
    </table>
    <div class="qr-code">
        <img src="{{ $qrDataUri }}" alt="ZATCA QR">
    </div>
</body>
</html>

Method 5: PDF with mpdf (for ERP System or E-commerce)

use Mpdf\Mpdf;

$mpdf = new Mpdf(['mode' => 'utf-8', 'format' => 'A4']);
$qrText = Zatca::phase1()->generateQrCodeText(...);
$qrDataUri = Zatca::qr()->renderAsDataUri($qrText, 150);

$html = '<div style="position: absolute; bottom: 10mm; right: 10mm;">
    <img src="' . $qrDataUri . '" width="150" height="150"/>
</div>';

$mpdf->WriteHTML($html);
$mpdf->Output('invoice.pdf', 'D');

Method 6: Advanced Output (Base64, Data URI, File)

// Base64-encoded image (SVG or PNG depending on installed packages)
$base64 = Zatca::qr()->renderAsBase64($qrText, 200);

// Data URI ready for <img> tag
$dataUri = Zatca::qr()->renderAsDataUri($qrText, 200);

// Save directly to file (SVG or PNG)
Zatca::qr()->renderToFile($qrText, storage_path('app/public/qr/invoice.svg'), 200);

These methods work automatically — output format depends on which package is installed (see Method 1).

API Routes (Optional)

The package registers HTTP API endpoints. You do not need these for basic Phase 1 or Phase 2 usage — they are an alternative to calling the package methods directly from PHP code or Artisan commands.

These routes are separate from the QR rendering methods above. By default they use the api middleware group — change it with ZATCA_API_MIDDLEWARE in your .env.

Method	Path	Description
`POST`	`/zatca/onboard`	Onboard via API — requires `otp` and optional `solution_name`
`POST`	`/zatca/invoice/sync`	Dispatch a sync job — requires `invoice_serial_number`
`GET`	`/zatca/status`	Returns current phase, environment, and enabled status

These routes are completely independent from the QR rendering methods above. You can use them with any HTTP client (Postman, cURL, your frontend app, etc.).

Testing with cURL

Test the routes directly with cURL:

# Check package status
curl -X GET http://localhost:8000/zatca/status \

Offline Mode & Queue Sync (Optional)

The package natively supports offline invoice preparation with queue-based synchronization. You do not need this for basic Phase 1 or Phase 2 — it is only useful if you want to generate and sign invoices when offline, then sync them to ZATCA later.

Configuration

# Use database queue for persistence across restarts
ZATCA_QUEUE_CONNECTION=database
ZATCA_QUEUE_NAME=zatca

# Retry settings
ZATCA_QUEUE_TRIES=5
ZATCA_RETRY_DELAY_MINUTES=60

Run the Queue Worker

php artisan queue:work --queue=zatca --tries=3 --delay=3600

Sync Pending Invoices Manually

# Sync a specific invoice
php artisan zatca:sync --invoice=INV-001

# Sync all pending invoices
php artisan zatca:sync --all

Data Flow

Phase 1 Flow:
  Invoice Data (5 tags) --> TLV Encoder --> Base64 --> QR Image

Phase 2 Flow:
  1. Generate EC Key Pair (secp256k1)
  2. Generate CSR
  3. Submit CSR + OTP --> ZATCA API --> Compliance Certificate
  4. Build UBL 2.1 XML Invoice
  5. Hash Invoice (SHA-256)
  6. Create Digital Signature (ECDSA)
  7. Generate TLV QR (9 tags)
  8. Embed XAdES Signature
  9. Submit to ZATCA:
       - Sandbox:    POST /compliance/invoices
       - Production: POST /invoices/clearance OR /reporting
  10. Handle Response --> Fire Events --> Log

Events (Optional)

The package fires events that you can listen to in your application. Not needed for basic usage — only useful if you want to react to invoice submission results (e.g., update your database when an invoice is cleared).

Event	Description	Payload
`InvoiceCleared`	Invoice successfully cleared (production)	`invoiceData`, `ComplianceResultDTO`
`InvoiceReported`	Invoice reported successfully (sandbox)	`invoiceData`, `ComplianceResultDTO`
`InvoiceComplianceChecked`	Compliance check completed	`invoiceData`, `ComplianceResultDTO`
`InvoiceFailed`	Invoice submission failed	`invoiceData`, `errorMessage`

Example Listener

namespace App\Listeners;

use Aghfatehi\Zatca\Events\InvoiceCleared;

class UpdateInvoiceStatus
{
    public function handle(InvoiceCleared $event): void
    {
        $serial = $event->invoiceData['invoice_serial_number'];
        
        // Update your invoice status in DB
        Invoice::where('serial_number', $serial)
            ->update(['zatca_status' => 'cleared']);
    }
}

Register in EventServiceProvider:

protected $listen = [
    \Aghfatehi\Zatca\Events\InvoiceCleared::class => [
        \App\Listeners\UpdateInvoiceStatus::class,
    ],
    \Aghfatehi\Zatca\Events\InvoiceFailed::class => [
        \App\Listeners\MarkInvoiceAsFailed::class,
    ],
];

Artisan Commands

Command	Required	Description
`php artisan zatca:onboard`	Phase 2	Interactive onboarding wizard (generates keys, CSR, gets certificate)
`php artisan zatca:check`	Phase 1 & 2	Check package readiness (OpenSSL, config, etc.). Run after install.
`php artisan zatca:sync`	Optional	Sync invoices to ZATCA via queue (single or all pending)

Testing

composer test

Or with PHPUnit directly:

vendor/bin/phpunit

Security & Logging (Optional)

Logging is enabled by default but not required for basic Phase 1 or Phase 2. It is useful for audit trails and debugging.

Logging Design

Levels: info, warning, error only
Non-blocking: Uses Laravel's async-safe log channel
PII Masking: Automatically masks otp, secret, password, private_key, csr
Truncation: Values exceeding 500 chars are truncated
Audit trail: Optional zatca_invoice_logs database table for compliance tracking

Security Best Practices

Never store private keys or secrets in code
Use .env variables or a secrets manager for credentials
Restrict queue worker access to authorized personnel
Enable PII masking in production (ZATCA_LOG_MASK_PII=true)
Use HTTPS for all ZATCA API communication (enforced by cURL)
Rotate OTP and secrets according to ZATCA guidelines

Integration Scenarios

Scenario 1: New Project — Both Phases

ZATCA_PHASE=both
ZATCA_ENVIRONMENT=sandbox

Start with Phase 1 QR codes immediately, then add Phase 2 when ready.

Scenario 2: Phase 1 Only (Existing System)

ZATCA_PHASE=phase_1

Just generate QR codes. No API keys needed.

Scenario 3: Phase 2 Only (Already have Phase 1)

ZATCA_PHASE=phase_2

You already generate QR codes elsewhere (or via another package). This package handles the API integration.

Scenario 4: External API Integration

If your ERP exposes an API, you can use the package's internal services directly:

use Aghfatehi\Zatca\Services\Phase2Service;

class YourController
{
    public function sync(Request $request, Phase2Service $phase2)
    {
        $invoice = InvoiceDTO::fromArray($request->all());
        $result = $phase2->signInvoice($invoice, ...);
        // ...
    }
}
