Make Your First Request

# Create a simple HTML file
echo '<h1>Hello World</h1>' > index.html

# Generate PDF
curl -X POST https://api.syntaxdoc.com/pdf/generate \
  -H "X-API-Key: sk_live_your_api_key" \
  -F "files=@index.html" \
  -F 'options={"fileName": "hello", "format": "A4"}' \
  --output hello.pdf

const formData = new FormData();

// Add HTML file
const htmlContent = '<h1>Hello World</h1>';
formData.append('files', new Blob([htmlContent], { type: 'text/html' }), 'index.html');

// Add options
formData.append('options', JSON.stringify({
  fileName: 'hello',
  format: 'A4',
  margin: { top: '1cm', bottom: '1cm', left: '1cm', right: '1cm' }
}));

const response = await fetch('https://api.syntaxdoc.com/pdf/generate', {
  method: 'POST',
  headers: {
    'X-API-Key': 'sk_live_your_api_key',
  },
  body: formData
});

const blob = await response.blob();
// Save or use the PDF blob

import requests
import json

# Prepare files and options
files = {
    'files': ('index.html', '<h1>Hello World</h1>', 'text/html')
}
data = {
    'options': json.dumps({
        'fileName': 'hello',
        'format': 'A4',
        'margin': {'top': '1cm', 'bottom': '1cm', 'left': '1cm', 'right': '1cm'}
    })
}

response = requests.post(
    'https://api.syntaxdoc.com/pdf/generate',
    headers={'X-API-Key': 'sk_live_your_api_key'},
    files=files,
    data=data
)

with open('hello.pdf', 'wb') as f:
    f.write(response.content)

Host Your PDF (Optional)

Want a shareable URL instead of downloading the PDF? Add host: true to your options:

formData.append('options', JSON.stringify({
  fileName: 'hello',
  format: 'A4',
  host: true  // Returns a URL instead of the PDF binary
}));

const response = await fetch('https://api.syntaxdoc.com/pdf/generate', {
  method: 'POST',
  headers: { 'X-API-Key': 'sk_live_your_api_key' },
  body: formData
});

const { url, pdfId, expiresAt } = await response.json();
console.log(url); // https://api.syntaxdoc.com/api/hosted-pdfs/abc123

Batch Generation

Need to generate multiple PDFs at once? Use batch generation with real-time progress tracking:

const response = await fetch('https://api.syntaxdoc.com/pdf/generate-batch', {
  method: 'POST',
  headers: {
    'X-API-Key': 'sk_live_your_api_key',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    documents: [
      { fileName: 'invoice-001', htmlContent: '<h1>Invoice 001</h1>' },
      { fileName: 'invoice-002', htmlContent: '<h1>Invoice 002</h1>' },
      // Add as many as you need
    ],
    stream: true,  // Get real-time progress updates
    host: true     // Store as hosted ZIP file
  })
});

const { batchId } = await response.json();

// Stream progress with SSE
const eventSource = new EventSource(
  `https://api.syntaxdoc.com/pdf/progress/${batchId}/stream`
);

eventSource.addEventListener('progress', (event) => {
  const { current, total } = JSON.parse(event.data);
  console.log(`Generated ${current}/${total} PDFs`);
});

eventSource.addEventListener('complete', (event) => {
  const data = JSON.parse(event.data);
  const result = JSON.parse(data.message);
  console.log('Download:', result.downloadUrl);
  eventSource.close();
});

Advanced Features

Add QR Codes

Generate QR codes automatically by adding data-qr attributes to your HTML:

<!DOCTYPE html>
<html>
  <body style="text-align: center; padding: 40px;">
    <h1>Certificate of Completion</h1>
    <p>John Doe</p>
    
    <div style="margin-top: 40px;">
      <img data-qr="https://syntaxdoc.com/verify/cert-12345" 
           data-qr-size="200" 
           alt="Verification QR Code" />
    </div>
  </body>
</html>

No separate API calls needed - QR codes are generated automatically during PDF creation!
