KFAST Save Card (KNET Integration)

KFAST is an integration powered by the KNET Payment Gateway that allows customers to save their card details for future purchases—eliminating the need to re-enter information at checkout.

This feature enables a faster, more convenient, and secure payment experience for returning customers.

📘
Note
Cards saved via KFAST are securely managed by KNET, not UPayments.

🔑 Key Benefits of KFAST

Faster Checkout
Returning customers can complete transactions without re-entering card details.
Enhanced Security
Card information is stored and handled exclusively on KNET’s secure infrastructure.
Wide Acceptance
KFAST is supported by a large number of merchants across Kuwait, both online and offline.

🛠️ How to Enable KFAST

Follow these simple steps to implement the KFAST Save Card feature in your integration:

Create a customer token
Use the Create Customer Unique Token endpoint.
Pass the token during checkout
Provide the customeruniquetoken in the Add Charge API request.

KNET will handle the secure storage of card data. You can later fetch saved card details using the same customeruniquetoken.

✅
Works with both Whitelabel and Non-Whitelabel integrations

🚧
Important
The KFAST feature is not available in sandbox mode. Testing must be done in a live environment.
