### Create Shipping Guide in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This PHP snippet creates an electronic shipping guide using Greenter's Despatch model, configuring shipment details like transport mode, weights, directions, and recipient information. It builds the despatch document and submits it via the SEE client. Dependencies include Greenter model classes and a predefined $company object. Inputs are shipment parameters and client details; outputs are success or error messages, with the despatch object as intermediate data.

```php

    ]);

// Add detraction (SPOT - Sistema de Pago de Obligaciones Tributarias)
$invoice->setDetraccion((new Detraction())
    ->setCodBienDetraccion('027')          // Service code (Catálogo 54)

// Add perception tax (if applicable)
$invoice->setPerception((new SalePerception())
    ->setCodReg('01')                      // Perception regime
    ->setPorcentaje(2.00)                  // 2% perception

### Get Signed XML Without Sending

Source: https://context7.com/thegreenter/greenter/llms.txt

Generates and signs an XML document from an invoice without submitting it to SUNAT. Useful for previewing or storing the XML before official submission. Requires a SEE instance and invoice object.

```php
<?php
// Get signed XML for preview or storage
$xmlSigned = $see->getXmlSigned($invoice);

// Validate or store locally
file_put_contents('invoice-preview.xml', $xmlSigned);
echo "XML generated and signed successfully!\n";

// Later, send the pre-generated XML
$result = $see->sendXmlFile($xmlSigned);
```

--------------------------------

### Utilize SUNAT Tax Codes and Catalogs in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This example illustrates the usage of various SUNAT catalog codes for document classification within the Greenter library. It defines common codes for document types, client document types, tax affectation, units of measure, operation types, and reason codes for credit and debit notes.

```php
<?php
// Document types (Catálogo 01)
// '01' = Invoice (Factura)
// '03' = Receipt (Boleta)
// '07' = Credit Note (Nota de Crédito)
// '08' = Debit Note (Nota de Débito)
// '09' = Shipping Guide (Guía de Remisión)

// Client document types (Catálogo 06)
// '0' = Other
// '1' = DNI (national ID)
// '4' = Carnet de extranjería
// '6' = RUC (tax ID for companies)
// '7' = Passport

// Tax affectation codes (Catálogo 07)
// '10' = Taxed - Gravada
// '20' = Exempt - Exonerada
// '30' = Non-taxable - Inafecta
// '40' = Export

// Units of measure (Catálogo 03)
// 'NIU' = Unit
// 'ZZ' = Service
// 'KGM' = Kilogram
// 'MTR' = Meter

// Operation types (Catálogo 51)
// '0101' = Internal sale
// '0200' = Export
// '0401' = Non-domiciled sale

// Credit note reason codes (Catálogo 09)
// '01' = Item description correction
// '02' = Amount correction
// '03' = Discount
// '07' = Return of goods

// Debit note reason codes (Catálogo 10)
// '01' = Late payment interest
// '02' = Penalty increase
// '03' = Goods damage

$detail = (new SaleDetail())
    ->setTipAfeIgv('10')                   // Taxed operation
    ->setUnidad('NIU')                     // Unit measure
    ->setCodProducto('PROD001')
    ->setDescripcion('Product description')
    ->setCantidad(5);

$client = (new Client())
    ->setTipoDoc('6')                      // RUC for companies
    ->setNumDoc('20123456789');

$invoice = (new Invoice())
    ->setTipoDoc('01')                     // Invoice
    ->setTipoOperacion('0101');            // Internal sale

```

### Send Despatch via REST API in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This PHP snippet demonstrates using Greenter's REST API client to send a despatch document, including OAuth and SOL credentials setup, certificate loading, and async status polling. It builds on a predefined $despatch object. Dependencies include Greenter Api class, file_get_contents for certificate, and sleep for polling. Inputs are API credentials, despatch object, and ticket for status; outputs are success/error messages, status responses, and the last XML.

```php
<?php
use Greenter\Api;

// Initialize REST API client
$api = new Api([
    'auth' => 'https://api-seguridad.sunat.gob.pe/v1',
    'cpe' => 'https://api-cpe.sunat.gob.pe/v1'
]);

// Configure OAuth credentials
$api->setApiCredentials('client-id-from-sunat', 'client-secret-from-sunat');

// Configure SOL credentials
$api->setClaveSOL('20123456789', 'MYUSER', 'mypassword');

// Set digital certificate
$api->setCertificate(file_get_contents(__DIR__ . '/certificate.pem'));

// Set builder options
$api->setBuilderOptions(['cache' => false, 'strict_variables' => true]);

// Send despatch via REST
$result = $api->send($despatch);

if ($result->isSuccess()) {
    echo "Document sent successfully!\n";

    // For async documents, get ticket and poll status
    $ticket = $result->getTicket();
    if ($ticket) {
        sleep(2);  // Wait before checking status
        $statusResult = $api->getStatus($ticket);

        if ($statusResult->isSuccess()) {
            echo "Status: " . $statusResult->getCdrResponse()->getDescription() . "\n";
        }
    }
} else {
    echo "Error: " . $result->getError()->getMessage() . "\n";
}

// Retrieve the last signed XML
$lastXml = $api->getLastXml();
file_put_contents('last-document.xml', $lastXml);

```

### Create and Send Daily Summary in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This PHP snippet creates a daily summary document for receipts and modifications using Greenter models, sends it asynchronously to SUNAT, and polls for the processing status. It requires the Greenter library and assumes a $see service and $company object are set up. Limitations include async processing delays and potential SUNAT errors.

```php
<?php
use Greenter\Model\Summary\Summary;
use Greenter\Model\Summary\SummaryDetail;

// Create summary details for each document in the day
$detail1 = (new SummaryDetail())
    ->setTipoDoc('03')                     // 03 = Receipt
    ->setSerieNro('B001-456')              // Document being summarized
    ->setEstado('1')                       // 1 = Addition, 2 = Modification, 3 = Cancellation
    ->setClienteTipo('1')
    ->setClienteNro('43567890')
    ->setTotal(118.00)
    ->setMtoOperGravadas(100.00)
    ->setMtoIGV(18.00);

$detail2 = (new SummaryDetail())
    ->setTipoDoc('03')
    ->setSerieNro('B001-457')
    ->setEstado('1')
    ->setClienteTipo('1')
    ->setClienteNro('43567891')
    ->setTotal(236.00)
    ->setMtoOperGravadas(200.00)
    ->setMtoIGV(36.00);

// Build summary document
$summary = (new Summary())
    ->setFecGeneracion(new DateTime())     // Generation date
    ->setFecResumen(new DateTime('-1 day')) // Date of documents being summarized
    ->setCorrelativo('001')                // Daily sequential number
    ->setCompany($company)
    ->setMoneda('PEN')
    ->setDetails([$detail1, $detail2]);

// Send summary (returns ticket for async processing)
$result = $see->send($summary);

if ($result->isSuccess()) {
    $ticket = $result->getTicket();
    echo "Summary sent! Ticket: $ticket\n";

    // Poll for status (SUNAT processes async)
    $maxAttempts = 10;
    $attempt = 0;

    do {
        sleep(3);  // Wait 3 seconds between checks
        $statusResult = $see->getStatus($ticket);
        $attempt++;

        if ($statusResult->getCode() === '0') {
            echo "Summary accepted by SUNAT!\n";
            $cdr = $statusResult->getCdrResponse();
            echo "Description: " . $cdr->getDescription() . "\n";

            // Save CDR
            file_put_contents('summary-cdr.zip', $statusResult->getCdrZip());
            break;
        } elseif ($statusResult->getCode() === '98') {
            echo "Processing... (attempt $attempt/$maxAttempts)\n";
        } else {
            echo "Error: " . $statusResult->getError()->getMessage() . "\n";
            break;
        }
    } while ($attempt < $maxAttempts);

} else {
    echo "Error sending summary: " . $result->getError()->getMessage() . "\n";
}

```

### Send Pre-Generated XML

Source: https://context7.com/thegreenter/greenter/llms.txt

Demonstrates how to send a pre-generated and signed XML file to SUNAT. Shows both automatic and explicit methods for XML submission. Requires valid XML content and SEE instance.

```php
<?php
// Load existing XML file
$xmlContent = file_get_contents('invoice-preview.xml');

// Send to SUNAT using sendXmlFile (auto-detects document type)
$result = $see->sendXmlFile($xmlContent);

// Or use sendXml with explicit parameters
$result = $see->sendXml(
    \Greenter\Model\Sale\Invoice::class,  // Document class
    '20123456789-01-F001-00123',          // Filename
    $xmlContent                            // XML content
);

if ($result->isSuccess()) {
    echo "Pre-generated XML accepted!\n";
}
```

### Generate and Submit SUNAT Invoice using PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This code demonstrates creating an electronic invoice with details like company, client, line items with IGV tax calculations, and legends, then submitting it to SUNAT via SOAP for validation. It requires the Greenter library (autoloaded), a digital certificate, and SUNAT credentials. Inputs include invoice data and outputs are success/error responses with signed XML and CDR ZIP files saved locally; limitations include production endpoint usage requiring valid credentials and certificate.

### Configure SUNAT Service Endpoints in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This code snippet shows how to configure different SUNAT service endpoints for production, beta, and testing environments using the Greenter library. It also covers setting credentials and certificates, as well as configuring cache paths and builder options.

```php
<?php
use Greenter\See;
use Greenter\Ws\Services\SunatEndpoints;

$see = new See();

// Production environment
$see->setService(SunatEndpoints::FE_PRODUCCION);

// Beta/Testing environment
$see->setService(SunatEndpoints::FE_BETA);

// Custom endpoint
$see->setService('https://custom-endpoint.sunat.gob.pe/ol-ti-itcpfegem/billService');

// Set credentials (RUC + secondary user)
$see->setClaveSOL('20123456789', 'MYUSER', 'mypassword');

// Or combined credentials
$see->setCredentials('20123456789MYUSER', 'mypassword');

// Configure certificate
$see->setCertificate(file_get_contents('/path/to/certificate.pem'));

// Or from environment variable
$see->setCertificate(getenv('SUNAT_CERTIFICATE'));

// Set cache directory for Twig templates
$see->setCachePath('/tmp/greenter_cache');

// Configure builder options
$see->setBuilderOptions([
    'cache' => '/tmp/greenter_cache',  // Cache directory
    'strict_variables' => true,        // Strict mode
    'debug' => false,                  // Debug mode
    'autoescape' => false              // Disable HTML escaping
]);

```

### Handle SUNAT Responses and Validate Errors in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This snippet demonstrates comprehensive error handling for SUNAT responses. It checks for success, processes CDR responses, validates response codes, and handles specific SUNAT error codes. It also shows how to retrieve a ticket for asynchronous document processing.

```php
<?php
$result = $see->send($invoice);

if ($result->isSuccess()) {
    $cdr = $result->getCdrResponse();

    // Check response code
    $code = $cdr->getCode();

    if ($code === '0') {
        echo "Document accepted without observations\n";
    } elseif ($code >= 4000) {
        echo "Document accepted with observations:\n";
        foreach ($cdr->getNotes() as $note) {
            echo "- $note\n";
        }
    }

    // Response details
    echo "CDR ID: " . $cdr->getId() . "\n";
    echo "Description: " . $cdr->getDescription() . "\n";
    echo "Reference: " . $cdr->getReference() . "\n";

    // Save CDR
    $cdrZip = $result->getCdrZip();
    $filename = "R-{$invoice->getCompany()->getRuc()}-{$invoice->getTipoDoc()}-{$invoice->getSerie()}-{$invoice->getCorrelativo()}.zip";
    file_put_contents($filename, $cdrZip);

} else {
    // Handle error
    $error = $result->getError();
    $errorCode = $error->getCode();
    $errorMessage = $error->getMessage();

    echo "SUNAT Error [$errorCode]: $errorMessage\n";

    // Common error codes
    switch ($errorCode) {
        case '0151':
            echo "Invalid series format\n";
            break;
        case '2801':
            echo "Client document type invalid for invoice\n";
            break;
        case '3088':
            echo "Invalid currency code\n";
            break;
        default:
            echo "Check SUNAT error code documentation\n";
    }
}

// Get ticket for async documents
$ticket = $result->getTicket();
if ($ticket) {
    echo "Async processing - Ticket: $ticket\n";
}

```

### Create and Send Cancellation Communication in PHP

Source: https://context7.com/thegreenter/greenter/llms.txt

This PHP snippet generates a voided document communication for canceling same-day invoices using Greenter models, sends it asynchronously to SUNAT, and checks the processing status. It depends on the Greenter library with pre-configured $see service and $company, and includes support for multiple cancellation reasons. Note that it's designed for same-day cancellations with async polling, which may involve delays or failures.

```php
<?php
use Greenter\Model\Voided\Voided;
use Greenter\Model\Voided\VoidedDetail;

// Create details for each document to cancel
$detail1 = (new VoidedDetail())
    ->setTipoDoc('01')                     // Document type to cancel
    ->setSerie('F001')
    ->setCorrelativo('123')
    ->setDesMotivoBaja('ERROR EN EMISION'); // Cancellation reason

$detail2 = (new VoidedDetail())
    ->setTipoDoc('01')
    ->setSerie('F001')
    ->setCorrelativo('124')
    ->setDesMotivoBaja('OPERACION NO REALIZADA');

// Build voided document
$voided = (new Voided())
    ->setCorrelativo('001')                // Daily sequential number
    ->setFecGeneracion(new DateTime())     // Generation date
    ->setFecComunicacion(new DateTime())   // Communication date (today for same-day cancellation)
    ->setCompany($company)
    ->setDetails([$detail1, $detail2]);

// Send voided communication (async processing)
$result = $see->send($voided);

if ($result->isSuccess()) {
    $ticket = $result->getTicket();
    echo "Voided communication sent! Ticket: $ticket\n";

    // Poll for status
    sleep(3);
    $statusResult = $see->getStatus($ticket);

    if ($statusResult->getCode() === '0') {
        echo "Cancellation accepted!\n";
    } elseif ($statusResult->getCode() === '98') {
        echo "Still processing... check again later\n";
    }
} else {
    echo "Error: " . $result->getError()->getMessage() . "\n";
}

```
