API Integration Guide for Developers

Getting Started with Processing APIs

This comprehensive guide will help developers integrate document processing capabilities into their applications using modern API technologies.

API Overview

Our processing API provides RESTful endpoints for processing various document formats with support for:

• Multiple input formats (PDF, DOC, DOCX, etc.)
• Various output formats (Excel, Word, text, etc.)
• Batch processing capabilities
• Real-time status updates

Authentication

The API uses API key authentication. Include your key in the Authorization header:

Authorization: Bearer YOUR_API_KEY

Basic Usage

Here's a simple example of processing a PDF to Excel:

POST /api/process-file
Content-Type: multipart/form-data

{
  "file": "your-document.pdf",
  "output_format": "xlsx",
  "options": {
    "preserve_formatting": true
  }
}
      

Response Handling

The API returns JSON responses with processing status and download links for completed tasks.

Error Handling

Implement proper error handling for common scenarios like unsupported formats, file size limits, and network issues.

Rate Limiting

Understand API rate limits and implement appropriate throttling in your applications.

Best Practices

• Validate file types before upload
• Implement retry logic for failed requests
• Use webhooks for long-running processing tasks
• Cache results when appropriate

SDKs and Libraries

We provide SDKs for popular programming languages including JavaScript, Python, PHP, and .NET.
