Getting Started with the API

Step 1: Obtain API Credentials

API access is available for Business and Enterprise plan subscribers. To get your API key:

  1. Upgrade to Business or Enterprise plan
  2. Navigate to your dashboard settings
  3. Click "API Access" tab
  4. Generate a new API key
  5. Store your key securely (never commit to version control)

Security Warning: Never expose your API key in client-side code. Always make API calls from your backend server.

Step 2: Review API Documentation

Our comprehensive API documentation includes:

  • Complete endpoint reference
  • Request/response examples
  • Authentication details
  • Rate limiting information
  • Error code definitions
  • Code samples in multiple languages

API Authentication

BatchMorph API uses Bearer token authentication. Include your API key in the Authorization header of every request: 

Authorization: Bearer YOUR_API_KEY_HERE
Example Authentication Headers

import requests

API_KEY = "your_api_key_here"
headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

response = requests.post(
    "https://batchmorph.com/api/v1/convert",
    headers=headers,
    json={"format": "pdf", "file": file_data}
)

const axios = require('axios');

const API_KEY = process.env.BATCHMORPH_API_KEY;

const response = await axios.post(
    'https://batchmorph.com/api/v1/convert',
    { format: 'pdf', file: fileData },
    {
        headers: {
            'Authorization': `Bearer ${API_KEY}`,
            'Content-Type': 'application/json'
        }
    }
);

curl -X POST https://batchmorph.com/api/v1/convert \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: multipart/form-data" \
  -F "file=@document.docx" \
  -F "output_format=pdf"

Common API Workflows

Single File Conversion

Convert a single file from one format to another:

Request
POST /api/v1/convert

{
  "file": "base64_encoded_file",
  "input_format": "docx",
  "output_format": "pdf",
  "quality": "high"
}
Response
{
  "status": "success",
  "conversion_id": "abc123",
  "download_url": "https://...",
  "expires_at": "2025-10-..."
}
Batch Conversion

Process multiple files in a single API call:

POST /api/v1/batch-convert

{
  "files": [
    {"file": "file1_base64", "output_format": "pdf"},
    {"file": "file2_base64", "output_format": "jpg"},
    {"file": "file3_base64", "output_format": "png"}
  ],
  "webhook_url": "https://your-app.com/webhook"
}
Webhook Notifications

For long-running conversions, use webhooks to receive completion notifications:

  • Provide a webhook_url in your conversion request
  • We'll POST conversion results to your endpoint when complete
  • Includes download URL and conversion metadata
  • Retries up to 3 times if webhook delivery fails

Rate Limits & Quotas

Plan Requests/Minute Concurrent Jobs Max File Size
Business 60 10 250 MB
Enterprise 300 50 1 GB

If you exceed rate limits, you'll receive a 429 Too Many Requests response. Implement exponential backoff and retry logic in your application.

Error Handling Best Practices

Common Error Codes
  • 400 Bad Request - Invalid parameters or malformed request
  • 401 Unauthorized - Missing or invalid API key
  • 403 Forbidden - API access not enabled for your plan
  • 413 Payload Too Large - File exceeds size limit
  • 415 Unsupported Media Type - Invalid input format
  • 429 Too Many Requests - Rate limit exceeded
  • 500 Internal Server Error - Server processing error
Example Error Response
{
  "error": {
    "code": "UNSUPPORTED_FORMAT",
    "message": "Input format 'xyz' is not supported",
    "details": "Supported formats: pdf, docx, jpg, png, heic, mov, mp4"
  }
}

Security Best Practices

API Key Security
  • Store keys in environment variables
  • Never commit keys to version control
  • Rotate keys periodically
  • Use separate keys for dev/production
  • Revoke compromised keys immediately
Data Security
  • All API calls use HTTPS encryption
  • Files are deleted after 24 hours
  • No file content is logged or stored
  • Webhook URLs should use HTTPS
  • Validate webhook signatures
