pay_ccavenue 1.1.0

A simple library to setup payment integration with CCAvenue

pay_ccavenue

A Python package for seamless integration with CCAvenue payment gateway.

Features

• Easy-to-use API for CCAvenue integration
• Secure encryption and decryption of payment data
• Flexible configuration via environment variables or direct instantiation
• Type hints for better code reliability

Current Limitations

• This package does not yet support iframe integration with CCAvenue. It currently provides basic encryption and decryption functionality for standard integration.

Installation

Install the package using pip:

pip install pay_ccavenue

Quick Start

1. Import the CCAvenue class:

from pay_ccavenue import CCAvenue

2. Initialize the CCAvenue object:

# Using environment variables
ccavenue = CCAvenue()

# Or, passing credentials directly
ccavenue = CCAvenue(
    working_key="YOUR_WORKING_KEY",
    access_code="YOUR_ACCESS_CODE",
    merchant_code="YOUR_MERCHANT_CODE",
    redirect_url="YOUR_REDIRECT_URL",
    cancel_url="YOUR_CANCEL_URL"
)

3. Encrypt payment data:

form_data = {
    "order_id": "123456",
    "amount": "1000.00",
    "currency": "INR",
    # Add other required fields
}

encrypted_data = ccavenue.encrypt(form_data)

4. Decrypt response data:

response_data = {
    "encResp": "ENCRYPTED_RESPONSE_FROM_CCAVENUE"
}

decrypted_data = ccavenue.decrypt(response_data)

5. Handle Webhook/Notification:

# In your webhook endpoint
webhook_payload = request.form  # Get the POST data
webhook_data = ccavenue.process_webhook(webhook_payload)

if webhook_data.order_status == "Success":
    print(f"Order {webhook_data.order_id} was successful")
    print(f"Tracking ID: {webhook_data.tracking_id}")
    print(f"Bank Ref: {webhook_data.bank_ref_no}")
elif webhook_data.risk_status == "High":
    print(f"Warning: High risk transaction {webhook_data.tracking_id}")
    print(f"Reason: {webhook_data.risk_reason}")

Configuration

Environment Variables

Set the following environment variables to configure the package:

• CCAVENUE_WORKING_KEY: Your CCAvenue working key
• CCAVENUE_ACCESS_CODE: Your CCAvenue access code
• CCAVENUE_MERCHANT_CODE: Your CCAvenue merchant code
• CCAVENUE_REDIRECT_URL: URL to redirect after successful payment
• CCAVENUE_CANCEL_URL: URL to redirect after cancelled payment

Direct Instantiation

Pass the configuration parameters directly when creating the CCAvenue object:

ccavenue = CCAvenue(
    working_key="YOUR_WORKING_KEY",
    access_code="YOUR_ACCESS_CODE",
    merchant_code="YOUR_MERCHANT_CODE",
    redirect_url="YOUR_REDIRECT_URL",
    cancel_url="YOUR_CANCEL_URL"
)

API Reference

CCAvenue Class

Methods

• encrypt(data: Dict[str, Any]) -> str: Encrypts the payment data
• decrypt(data: Dict[str, str]) -> Dict[str, str]: Decrypts the response data
• process_webhook(response_body: Dict[str, str]) -> CCavenueWebhookData: Decrypts and processes webhook data

CCavenueFormData Class

Represents the form data required for CCAvenue payment processing. It includes mandatory and optional fields, and provides methods for data manipulation and validation.

Important Fields

• merchant_id: CCAvenue merchant ID
• order_id: Unique order identifier
• currency: Payment currency (default: "INR")
• amount: Payment amount
• redirect_url: URL for successful payment redirection
• cancel_url: URL for cancelled payment redirection

For a complete list of fields, refer to the CCavenueFormData class documentation.

Security Considerations

• The package uses AES encryption with CBC mode for secure communication with CCAvenue.
• Ensure that your working key and other sensitive information are kept secure and not exposed in your codebase.
