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

• IC5 Commerce

• An active Klarna merchant account

• A supported Klarna country, currency, and locale combination

Important Information

Recurring billing agreements and automatic subscription renewals are not currently supported.

Available Klarna payment options depend on your merchant agreement, customer location, purchase currency, and Klarna account configuration. Klarna approval is subject to Klarna’s own eligibility and risk assessment.
