✅ Production Tested — Full onboarding flow (CSR → Compliance → 6 Invoice Types → Production Certificate → Invoice Reporting) successfully tested against ZATCA production API on March 31, 2026 using Ubuntu 24.04 / PHP 8.4.

Introduction

PHP-ZATCA-XML is a PHP library for generating ZATCA-compliant e-invoices (Fatoora). It handles the full lifecycle: certificate generation, XML invoice creation, digital signing, QR codes, and API submission to ZATCA.

Built to match the official ZATCA Java SDK (R3.4.8) specifications: secp256k1 keys, SHA256withECDSA signatures, UBL 2.1 XML, and all three environment tiers.

Features

• Certificate Builder aligned with ZATCA SDK (CSR generation, secp256k1, proper DN order, Arabic support)
• Invoice Generation for Standard and Simplified invoices (Invoice, Credit Note, Debit Note)
• Digital Signing with XAdES-BES enveloped signatures
• QR Code Generation per ZATCA TLV specification
• Full API Client covering all 6 ZATCA endpoints (compliance, production, reporting, clearance, renewal)
• Response Objects with typed accessors for validation results, warnings, and errors
• Data Mapper to build invoices from arrays/JSON (e-commerce integration)

Requirements

• PHP 8.1+
• Extensions: ext-dom, ext-openssl, ext-hash, ext-mbstring

Installation

composer require saleh7/php-zatca-xml

Quick Start: Production Onboarding

The full ZATCA onboarding flow in 4 steps:

Step 1: Generate CSR + Private Key

📄 Full example: examples/Certificates/GeneratorCertificate.php

use Saleh7\Zatca\CertificateBuilder;

(new CertificateBuilder)
    ->setOrganizationIdentifier('3XXXXXXXXXXXXX3')   // 15-digit VAT number
    ->setSerialNumber('ERP', '1.0', 'unique-device-uuid')
    ->setCommonName('ERP-886431145-3XXXXXXXXXXXXX3')
    ->setCountryName('SA')
    ->setOrganizationName('Your Company Name')       // Arabic supported
    ->setOrganizationalUnitName('Branch Name')
    ->setAddress('RRRD2929')
    ->setInvoiceType('1100')                         // Standard + Simplified
    ->setEnvironment(CertificateBuilder::ENV_PRODUCTION)
    ->setBusinessCategory('Supply activities')
    ->generateAndSave('output/certificate.csr', 'output/private.pem');

Environment options:

• ENV_PRODUCTION → ZATCA-Code-Signing (live)
• ENV_NONPROD → TSTZATCA-Code-Signing (sandbox/test)
• ENV_SIMULATION → PREZATCA-Code-Signing (pre-production)

Step 2: Request Compliance Certificate (CCSID)

📄 Full example: examples/Certificates/RequestComplianceCertificate.php

Get an OTP from fatoora.zatca.gov.sa, then:

use Saleh7\Zatca\ZatcaAPI;

$api = new ZatcaAPI('production'); // or 'sandbox', 'simulation'
$csr = file_get_contents('output/certificate.csr');

$result = $api->requestComplianceCertificate($csr, $otp);

$api->saveToJson(
    $result->getCertificate(),
    $result->getSecret(),
    $result->getRequestId(),
    'output/compliance_credentials.json'
);

Step 3: Compliance Check (6 Invoice Types)

📄 Full automated example: examples/Certificates/ComplianceCheck.php

Submit 6 test invoices to pass compliance validation:

$creds = json_decode(file_get_contents('output/compliance_credentials.json'), true);

$response = $api->validateInvoiceCompliance(
    $creds['certificate'],
    $creds['secret'],
    $signedInvoiceXml,
    $invoiceHash,
    $uuid
);

if ($response->isSuccess()) {
    echo "PASS: " . $response->getValidationStatus();
}

Required types: Standard Invoice, Standard Credit Note, Standard Debit Note, Simplified Invoice, Simplified Credit Note, Simplified Debit Note.

See examples/Certificates/ComplianceCheck.php for an automated script that generates, signs, and submits all 6 types.

Step 4: Request Production Certificate (PCSID)

📄 Included automatically in examples/Certificates/ComplianceCheck.php

After all 6 invoices pass:

$prodResult = $api->requestProductionCertificate(
    $creds['certificate'],
    $creds['secret'],
    $creds['requestId']
);

$api->saveToJson(
    $prodResult->getCertificate(),
    $prodResult->getSecret(),
    $prodResult->getRequestId(),
    'output/production_credentials.json'
);

Submitting Invoices

Reporting (B2C / Simplified)

📄 Full example: examples/InvoiceSimplified/simplified_invoice.php

$prod = json_decode(file_get_contents('output/production_credentials.json'), true);

$response = $api->submitReportingInvoice(
    $prod['certificate'], $prod['secret'],
    $signedXml, $invoiceHash, $uuid
);

$response->isReported();         // true if REPORTED
$response->getReportingStatus(); // "REPORTED"
$response->getValidationStatus();
$response->getWarningMessages();
$response->getErrorMessages();

Clearance (B2B / Standard)

📄 Full example: examples/InvoiceStandard/standard_invoice.php

$response = $api->submitClearanceInvoice(
    $prod['certificate'], $prod['secret'],
    $signedXml, $invoiceHash, $uuid
);

$response->isCleared();                // true if CLEARED
$response->getClearedInvoice();        // Base64 stamped invoice
$response->getDecodedClearedInvoice(); // XML string

Certificate Renewal

$renewed = $api->renewProductionCertificate(
    $prod['certificate'], $prod['secret'],
    $newCsr, $otp
);

Invoice Generation

From Array (e-commerce integration)

use Saleh7\Zatca\Mappers\InvoiceMapper;
use Saleh7\Zatca\GeneratorInvoice;

$invoiceData = [
    'uuid'            => '3cf5ee18-ee25-44ea-a444-2c37ba7f28be',
    'id'              => 'INV-001',
    'issueDate'       => '2025-01-15',
    'issueTime'       => '14:30:00',
    'currencyCode'    => 'SAR',
    'taxCurrencyCode' => 'SAR',
    'invoiceType'     => [
        'invoice' => 'simplified',  // or 'standard'
        'type'    => 'invoice',     // 'invoice', 'credit', or 'debit'
    ],
    'supplier' => [
        'registrationName' => 'Your Company',
        'taxId'            => '3XXXXXXXXXXXXX3',
        'identificationId' => 'XXXXXXXXXX',
        'identificationType' => 'CRN',
        'address' => [
            'street' => 'Main Street', 'buildingNumber' => '1234',
            'subdivision' => 'District', 'city' => 'Riyadh',
            'postalZone' => '12345', 'country' => 'SA',
        ],
    ],
    'invoiceLines' => [
        [
            'id' => 1, 'unitCode' => 'PCE', 'quantity' => 2,
            'lineExtensionAmount' => 200,
            'item' => [
                'name' => 'Product Name',
                'classifiedTaxCategory' => [['percent' => 15, 'taxScheme' => ['id' => 'VAT']]],
            ],
            'price' => ['amount' => 100, 'unitCode' => 'UNIT'],
            'taxTotal' => ['taxAmount' => 30, 'roundingAmount' => 230],
        ],
    ],
    // ... taxTotal, legalMonetaryTotal, etc.
];

$invoice = (new InvoiceMapper())->mapToInvoice($invoiceData);
$xml = GeneratorInvoice::invoice($invoice)->getXML();

Signing

use Saleh7\Zatca\Helpers\Certificate;
use Saleh7\Zatca\InvoiceSigner;

$certificate = new Certificate($certString, $privateKeyString, $secret);
$signer = InvoiceSigner::signInvoice($xml, $certificate);

$signedXml   = $signer->getInvoice();
$invoiceHash = $signer->getHash();
