Payment Flow

When a customer selects Klarna during checkout, the application creates a Klarna Payments session and securely redirects the customer to the Klarna Hosted Payment Page.

After the customer completes or cancels the payment, the application verifies the session directly with Klarna and updates the corresponding IC5 transaction. Payment callbacks are processed independently, allowing transactions to complete even if the customer closes the browser before returning to your community.

Security

Each payment session receives a unique callback secret. Incoming events are validated, deduplicated, and verified against Klarna before an IC5 transaction is approved.

The application also validates the order amount, currency, transaction reference, and Klarna order details before completing a payment.

Requirements

• Invision Community 5
