4 Types of Payment Gateway Integration

Offsite Payment

One of the simplest payment integration method is the “Simple Checkout Method“. For this method, the gateway is used by an external service. When customers click a “Purchase” or “Buy Now” button on the site, they are redirected to the payment service provider’s online site. For instance, they can be sent to PayPal, PayU, Authorize.Net to create a safe transaction. This is the easiest and simplest method to integrate your payment method on the site.


  • No security concerns
  • You don’t have to continue to maintain the payment gateway.
  • Your website doesn’t have to be PCI compliant.


  • The customer will have to leave the site to make the payment.
  • Sometimes is open to failure because of a network error or due to a customer error
  • This method is sometimes prone to the man of the middle attacks.

Direct – Transparent Redirect

The second most commonly known method is the “Direct Post” method. This is where the form accepts the customer’s payment information and details are sent to the payment gateway where the transaction is completed. The customer data isn’t handled on your website.
