3. Getting Started

To get started with the Billdesk SDK, follow these steps:

3.1. Prerequisites

Before you begin, ensure that you have the following:

• A Billdesk merchant account.
• Basic knowledge of programming and API integration.
• Access to the development environment for your application.

3.2. Installation

To install the Billdesk SDK, follow these steps:

1. Download the SDK: Obtain the SDK package from the Billdesk developer portal.
2. Include the SDK in Your Project: Add the SDK files to your project directory. If you are using a package manager, follow the specific instructions for your platform.

3.3. Configuration

Configure the SDK by providing the necessary credentials and settings:

1. API Keys: Enter your Billdesk API keys in the configuration file.
2. Callback URLs: Set up callback URLs to handle payment status updates and notifications.

4. Integrating Payment Features

4.1. Initiating Transactions

To initiate a payment transaction, use the SDK's provided methods to send a request to the Billdesk server. Here is a sample code snippet in Python:

python
import billdesk_sdk

# Initialize the SDK
sdk = billdesk_sdk.initialize(api_key='YOUR_API_KEY')

# Create a payment request
response = sdk.create_payment(
    amount=1000,
    currency='INR',
    description='Product Purchase',
    callback_url='https://yourwebsite.com/callback'
)

# Handle the response
if response.success:
    print("Transaction initiated successfully")
else:
    print("Error initiating transaction:", response.error_message)

4.2. Handling Callbacks

To process callback notifications from Billdesk, implement a callback handler in your application. This handler will receive updates about the payment status and should update your records accordingly.

python
from flask import Flask, request

app = Flask(__name__)

@app.route('/callback', methods=['POST'])
def handle_callback():
    data = request.form
    # Process payment status
    payment_status = data.get('status')
    transaction_id = data.get('transaction_id')
    # Update your database with the payment status
    return 'Callback received', 200

4.3. Managing Transactions

The SDK also provides methods for managing transactions, such as querying transaction status and handling refunds. Refer to the SDK documentation for detailed instructions on these operations.

5. Best Practices

To ensure a smooth integration and optimal performance, follow these best practices:

• Security: Always use HTTPS for secure communication between your application and Billdesk servers. Regularly update your SDK to include the latest security patches.
• Testing: Thoroughly test the integration in a staging environment before deploying it to production. Use Billdesk's test mode to simulate transactions.
• Error Handling: Implement robust error handling to manage unexpected issues and provide a seamless user experience.

6. Troubleshooting

Common issues and their solutions:

• Integration Errors: Check for configuration issues or missing credentials.
• Transaction Failures: Verify the transaction details and ensure sufficient funds are available.
• Callback Issues: Ensure that your callback URL is correctly configured and accessible from Billdesk servers.

7. Conclusion

The Billdesk SDK is a powerful tool for integrating payment processing into your application. By following the steps outlined in this guide, you can efficiently implement and manage payment transactions, providing a secure and seamless experience for your users. For more detailed information and support, refer to the official Billdesk SDK documentation.
