Step 1: Choose the Right Payment Gateway Provider

Before you can integrate, you need to select a payment gateway that suits your business model, target audience, and technical requirements. Key factors to consider include:

• Supported payment methods (e.g., FPX, DuitNow, credit cards, eWallets)
  
  
• Setup and transaction fees
  
  
• Integration options (API, hosted pages, plugins)
  
  
• Security certifications like PCI DSS compliance
  
  
• Customer support quality

Step 2: Register for a Merchant Account

Most Malaysian gateways (e.g., Paydibs, iPay88, Razer Merchant Services) will require you to register a merchant account. Be prepared to submit:

• Company registration documents (SSM)
  
  
• Bank account details
  
  
• Business website URL
  
  
• Business profile or description of services
  
  
• Copy of business owner’s NRIC
  
  

Approval times vary from 2 to 7 working days depending on the provider.

Step 3: Select Your Integration Method

Malaysian businesses typically choose one of these three methods:

1. Hosted Payment Page

Redirects customers to a secure external page to complete payments. Best for businesses without an in-house developer.

Pros:

• Minimal development needed
  
  
• PCI compliance handled by the gateway
  
  

Cons:

• Less control over the checkout experience
  
  

2. API/Server Integration

For full control, integrate the gateway directly into your site using APIs.

Pros:

• Custom branding
  
  
• Real-time payment confirmation
  
  

Cons:

• Requires backend development
  
  
• You must handle some compliance yourself
  
  

3. E-Commerce Platform Plugins

Platforms like Shopify, WooCommerce, and Magento offer gateway plugins (e.g., Paydibs for WooCommerce).

Pros:

• Quick setup
  
  
• Often comes with technical support
  
  

Cons:

• Limited customization depending on the plugin
  
  

Step 4: Perform Technical Integration

This step will depend on your chosen method:

• Hosted page: Copy-paste the payment URL or embed a button on your checkout page
  
  
• API: Use your provider’s documentation to implement the payment logic, webhook handlers, and error checking
  
  
• Plugin: Install and configure the plugin from your platform’s extension marketplace
  
  

Make sure to test:

• Successful transactions
  
  
• Failed payments
  
  
• Refund processing
  
  
• Mobile responsiveness

Step 5: Perform UAT (User Acceptance Testing)

Before going live, perform UAT with sandbox credentials provided by your payment gateway. Test different payment flows and ensure that:

• The checkout experience is smooth
  
  
• Users are redirected properly
  
  
• Transaction records are logged in your backend
  
  
• Emails/receipts are sent
  
  

Once confirmed, switch from sandbox to live mode in your dashboard.

Step 6: Post-Integration Best Practices

Once your payment gateway is live, follow these best practices to optimize performance and compliance:

• Use HTTPS across all pages
  
  
• Display trust signals like SSL badges and accepted payment icons
  
  
• Monitor your transactions daily for fraud
  
  
• Offer multiple payment options, including FPX, DuitNow, and eWallets
  
  
• Keep customer support ready in case of failed or duplicate payments
