Getting Started

To start using the SecurePDF Encryptor API, follow these steps:

• Sign Up: Register for an API key to access the service.
• Authenticate Requests: Use your API key in the headers to authenticate API calls.
• Upload a PDF: Send a PDF file for encryption using the designated API endpoint.
• Receive Encrypted File: Get a secure download link for the encrypted PDF.

Authentication

All requests require an API key, passed in the headers as follows:

{ "x-api-key": "YOUR_API_KEY", "x-app-username": "YOUR-API_USERNAME" }

Note: Keep your API key secure and do not share it publicly.

API Endpoints

The main endpoint for encrypting PDFs:

{ "POST": "/file/encrypt-pdf" }

Request Parameters:

• filepart: The PDF file to encrypt (required).
• password: A strong password for encryption (required).

Response Example:

{
    "msg": "Your file was encrypted successfully. Use the link below to download the PDF.",
    "status": 200,
    "data": "https://assets.cysecinnovation.com/encrypted_example.pdf"
  }

Rate Limits

To ensure fair usage, API requests are limited:

• 50 requests per minute: Exceeding this limit results in a 429 Too Many Requests response.

For higher limits, contact our support team.

Error Handling

The API uses standard HTTP status codes for error handling:

{
    "status": 400,
    "error": "Bad Request",
    "message": "Wrong x-api-key and/or x-app-username"
  }

{
    "status": 400,
    "error": "Bad Request",
    "message": "Insufficient balance for live API request."
  }

Debugging Tips:

• Ensure your API key is valid and included in the request headers.
• Check that the uploaded file meets the format and size requirements.
• Monitor rate limits to avoid request rejections.
