Docsend to PDF API Documentation

Content-Type: application/json

{
  "url": "https://docsend.com/view/abcdefg",       // Required
  "email": "user@example.com",                     // Optional, for password-protected documents
  "passcode": "document-password",                 // Optional, for password-protected documents
  "searchable": true                               // Optional, default is false
}

On success, the API returns the PDF document directly with:

• Content-Type: application/pdf
• Content-Disposition: attachment; filename=*.pdf

The API also includes rate limiting headers:

• X-RateLimit-Limit: Maximum requests allowed in the time window
• X-RateLimit-Remaining: Remaining requests in the current time window
• X-RateLimit-Reset: Timestamp when the rate limit window resets

Errors are returned as JSON with appropriate HTTP status codes:

{
  "error": "Error message"
}

Common error status codes:

• 400 - Bad Request (missing or invalid parameters)
• 429 - Too Many Requests (rate limit exceeded)
• 500 - Internal Server Error

To ensure fair usage and service stability, the following rate limits apply:

• Maximum 5 requests per second per IP address

If you exceed this limit, requests will be rejected with a 429 status code and include a Retry-After header indicating when you can retry.

cURL

# Basic usage - download directly to a file
curl -L -X POST https://docsend2pdf.com/api/convert \
  -H "Content-Type: application/json" \
  -d '{"url": "https://docsend.com/view/abcdefg"}' \
  --output document.pdf

# With additional options for password-protected documents
curl -L -X POST https://docsend2pdf.com/api/convert \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://docsend.com/view/abcdefg",
    "email": "user@example.com",
    "passcode": "document-password",
    "searchable": true
  }' \
  --output document.pdf

JavaScript/Node.js

// Using fetch (browser or Node.js 18+)
async function convertDocsend(url) {
  const response = await fetch('https://docsend2pdf.com/api/convert', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      url: url,
      searchable: true
    })
  });

  if (!response.ok) {
    if (response.status === 429) {
      const retryAfter = response.headers.get('Retry-After');
      console.error(`Rate limit exceeded. Retry after ${retryAfter} seconds`);
      return null;
    }

    const errorData = await response.json();
    console.error('API Error:', errorData.error);
    return null;
  }

  // Return the PDF as a blob
  return await response.blob();
}

// Example usage
const pdfBlob = await convertDocsend('https://docsend.com/view/abcdefg');
if (pdfBlob) {
  // Do something with the PDF blob
  // e.g., save to file, display in browser, etc.
