Installation

composer require pdfen/php-sdk

Quick Start

use Pdfen\Sdk\PdfenClient;

// Initialize client with API token
$client = new PdfenClient('your-api-token');

// Get user info
$user = $client->user()->get();
echo "Available credits: {$user->credits}\n";

// Convert a file (async mode)
$conversion = $client->convert()
    ->files(['document.docx'])
    ->workflow(1) // workflow ID
    ->async()
    ->execute();

echo "Execution ID: {$conversion->executionId}\n";

// Check status
$status = $client->executions()->get($conversion->executionId);
echo "Status: {$status->status}\n";

// Download when complete
if ($status->isCompleted()) {
    $client->executions()->download($conversion->executionId, 'output.pdf');
    echo "Downloaded to output.pdf\n";
}

Usage Examples

Synchronous Conversion

$conversion = $client->convert()
    ->files(['image.jpg'])
    ->workflow(2)
    ->sync() // Wait for completion
    ->execute();

if ($conversion->isCompleted()) {
    $client->executions()->download($conversion->executionId, 'result.pdf');
}

Multiple Files with Options

$conversion = $client->convert()
    ->files(['doc1.docx', 'doc2.docx', 'image.jpg'])
    ->workflow(1)
    ->options([
        'convert_metadata' => true,
        'page_size' => 'a4'
    ])
    ->async()
    ->execute();

echo "Credits charged: {$conversion->creditsCharged}\n";
echo "Credits remaining: {$conversion->creditsRemaining}\n";

Conversion with Advanced Options

// PDF to Word with page range and password
$conversion = $client->convert()
    ->files(['document.pdf'])
    ->workflow(10) // PDF to Word workflow
    ->options([
        'page_range' => '1-10,15-20',
        'output_format' => 'docx',
        'password' => 'secret123', // If PDF is password-protected
        'ocr' => true,
        'ocr_language' => 'nld'
    ])
    ->async()
    ->execute();

// Get available options for a workflow
$options = $client->workflows()->options(10);
foreach ($options->options as $option) {
    echo "{$option->key}: {$option->name}\n";
}

Cover Page Templates

// Get available cover templates
$templates = $client->user()->coverTemplates();

foreach ($templates->templates as $template) {
    echo "Template: {$template->name} (ID: {$template->template_id})\n";
}

// Use cover template in conversion
$conversion = $client->convert()
    ->files(['document.pdf'])
    ->workflow(5)
    ->coverTemplateId(123) // Use cover template ID 123
    ->execute();

List Available Workflows

$workflows = $client->user()->workflows();

foreach ($workflows->userWorkflows as $workflow) {
    echo "- {$workflow->name} (ID: {$workflow->id})\n";
}

Check Credits

$credits = $client->user()->credits();

echo "Personal credits: {$credits->personalCredits}\n";
echo "Organization credits: {$credits->organizationCredits}\n";
echo "Total available: {$credits->totalAvailable}\n";

Data Extraction

Extract structured data from documents using AI. Each extraction type returns JSON by default, or can download as CSV/Excel.

Invoice Extraction

$result = $client->extract()
    ->files(['invoice.pdf'])
    ->locale('nl')
    ->invoice();

echo "Credits charged: {$result->creditsCharged}\n";

foreach ($result->results as $file) {
    foreach ($file['invoices'] as $invoice) {
        echo "{$invoice['vendor_name']}: {$invoice['total']}\n";
    }
}

// Download as CSV
$client->extract()
    ->files(['invoice.pdf'])
    ->format('csv')
    ->invoiceDownload('/tmp/invoices.csv');

Email Extraction

$result = $client->extract()
    ->files(['message.eml'])
    ->email();

foreach ($result->results as $file) {
    foreach ($file['emails'] as $email) {
        echo "{$email['subject']}: {$email['from']['email']}\n";
    }
}

Form, Table, Legal Extraction

// Forms - extracts field names and values
$result = $client->extract()->files(['form.pdf'])->form();

// Tables - extracts tabular data
$result = $client->extract()->files(['report.pdf'])->table();

// Legal - extracts clauses, parties, dates
$result = $client->extract()->files(['contract.pdf'])->legal();

Floor Plan Extraction

$result = $client->extract()
    ->files(['floorplan.pdf'])
    ->template('full_detail') // room_overview, dimensions, or full_detail
    ->floorPlan();

foreach ($result->results as $file) {
    foreach ($file['rooms'] ?? [] as $room) {
        echo "{$room['name']}: {$room['area']} m²\n";
    }
}

Download Formats

All extraction types support binary download (CSV, Excel). Invoice also supports UBL:

$client->extract()->files(['data.pdf'])->format('excel')->tableDownload('/tmp/tables.xlsx');
$client->extract()->files(['invoice.pdf'])->format('ubl')->invoiceDownload('/tmp/invoice.xml');

Error Handling

use Pdfen\Sdk\Exceptions\InsufficientCreditsException;
use Pdfen\Sdk\Exceptions\ValidationException;
use Pdfen\Sdk\Exceptions\AuthenticationException;

try {
    $conversion = $client->convert()
        ->files(['large-file.pdf'])
        ->workflow(1)
        ->execute();

} catch (InsufficientCreditsException $e) {
    echo "Not enough credits: {$e->getMessage()}\n";
    echo "Credits needed: {$e->getCreditsNeeded()}\n";
    echo "Credits available: {$e->getCreditsAvailable()}\n";

} catch (ValidationException $e) {
    echo "Validation error: {$e->getMessage()}\n";
    print_r($e->getErrors());

} catch (AuthenticationException $e) {
    echo "Authentication failed: {$e->getMessage()}\n";
}
