How to Integrate Barclay Payment Gateway: A Step-by-Step Guide

Introduction:

In today's world of e-commerce, ensuring secure and seamless payment integration is crucial for any website. This post will walk you through the process of integrating the Barclaycard payment gateway using a test account, based on the sample code available in my GitHub repository.

What is Barclaycard Payment Gateway?

Barclaycard is a leading payment gateway that allows merchants to accept payments online securely. It supports multiple payment methods like Visa, MasterCard, and American Express, and it offers robust security with encryption and hashing methods.

Setting Up a Barclaycard Test Account

Before diving into the code, you need to set up a test account to try out the integration.

1. Create a Barclay Merchant Test Account:
   Go to the Barclaycard homepage and sign up for a test account. Once the account is created, you will need to:

   • Activate the account by accepting the terms and conditions.
   • Navigate to the Configuration section of your account.

2. Configure Global Security Parameters:

   • Under "Technical Information," go to "Global Security Parameters."
   • Select the SHA-256 Hash Algorithm.

3. Data and Origin Verification:

   • Set a SHA-IN passphrase and keep it secure.
   • In the application, set this passphrase under:

     C# Code:GatewayConfigurations.GatewaySHAInSecretKey

4. Transaction Feedback:

   • Choose to receive transaction feedback parameters on redirection URLs.
   • Set your SHA-OUT passphrase and store it in the app:

     C# Code:GatewayConfigurations.GatewaySHAOutSecretKey

5. Activate Payment Methods:

   • Add necessary payment brands such as Visa, MasterCard, or American Express.
   • Ensure the methods are activated.

6. Set Your PSPID:

   • Configure your PSPID in the app:

     C# Code:GatewayConfigurations.GatewayPSPID

Code Explanation

The sample code in the GitHub repository demonstrates how to integrate this payment gateway securely by:

1. Alphabetically Ordering Data:
   This is essential before sending data to the gateway to ensure consistency during hashing.

2. SHA-256 Encryption:
   The data is then converted into SHA-256 format, which ensures that sensitive information is hashed before it is submitted.

3. Submitting Data:
   Once the data is properly formatted and hashed, it is submitted to the gateway for processing.

4. Receiving Transaction Feedback:
   After the transaction is processed, feedback data is received. This data is validated using the SHA-OUT passphrase to confirm the transaction's authenticity and prevent fraud.

Key Benefits of Using Barclay Payment Gateway

• Security: By using SHA-256 hashing and passphrase validation, you ensure the data is secure.
• Support for Multiple Payment Methods: It allows the integration of a variety of payment methods.
• Transaction Feedback: You can monitor the status of each transaction and validate the integrity of the payment process.

Conclusion:

By following these steps and using the sample code provided, you can integrate Barclay's payment gateway into your site, ensuring secure and seamless payment processing. For a full demonstration and the source code, check out the repository on GitHub.
