Integrating a Cybersource Payment Gateway with a custom website involves several steps. Here’s a high-level guide to help you through the process:
### 1. **Get Access to Cybersource**
- **Sign Up**: First, you'll need to sign up for a Cybersource account if you don't have one already.
- **Get API Credentials**: Log in to the Cybersource Business Center and navigate to the “Account Management” section to obtain your API credentials (Merchant ID, API Key, Secret Key, etc.).
### 2. **Set Up Your Development Environment**
- **Choose a Development Language**: Determine the programming language and framework you are using for your custom website (e.g., PHP, Python, Ruby, JavaScript).
- **Install Required Libraries**: Cybersource provides SDKs and libraries for different programming languages. You can download these from the [Cybersource GitHub repository](https://github.com/Cybersource).
### 3. **Configure the Payment Gateway**
- **API Integration**: Depending on the language and SDK you are using, follow the integration guide provided by Cybersource. You will typically be interacting with their REST API for payment transactions.
- **REST API Endpoint**: Use the appropriate endpoint for your region (e.g., `https://api.cybersource.com`).
- **API Requests**: You'll be sending HTTP requests (POST/GET) to interact with the payment gateway, such as processing payments, refunds, etc.
- **Configure Payment Settings**: Set up your payment settings including payment methods, currency, and fraud detection settings in the Cybersource Business Center.
4. Implement Payment Processing
- **Front-End Integration**: On your website’s front end, create a payment form where users can enter their payment details. Ensure that sensitive data (like credit card numbers) is handled securely.
- **Back-End Integration**: Write server-side code to handle the payment processing. This code will:
- **Collect Payment Data**: Capture the payment data from the user.
- **Send API Request**: Use the Cybersource SDK or manually create an API request to send payment data to Cybersource.
- **Handle Response**: Process the response from Cybersource to confirm whether the payment was successful or if there were errors.
### 5. **Testing**
- **Use Test Credentials**: Before going live, use the test credentials provided by Cybersource to ensure everything works as expected.
- **Test Transactions**: Perform various test transactions to check for different scenarios, such as successful payments, declined payments, and error handling.
### 6. **Go Live**
- **Switch to Live Credentials**: Once testing is complete, switch to live credentials in the Cybersource Business Center.
- **Monitor Transactions**: After going live, monitor transactions to ensure there are no issues.
### 7. **Security Considerations**
- **PCI Compliance**: Ensure your website complies with PCI-DSS (Payment Card Industry Data Security Standard) regulations.
- **Data Encryption**: Use HTTPS to encrypt data sent between your website and Cybersource.
