Webshop Test

Before starting commercial sales, the Webshop allows you to verify screen configuration and payment flows using test accounts.

By registering a test ID according to the process, you can test Webshop functions without affecting the live service.

At least one Sandbox payment test is required to Start Selling.

To perform payment tests successfully, required API integrations must be completed in advance. For details, refer to the Webshop Integration Guide.

Test Environment Types

Webshop payment tests support both Sandbox Environment and Commercial Environment.

Sandbox Environment

• A virtual payment environment where no actual payment occurs.

• You can select either Payment Success or Payment Failure on the payment screen, and the selected response is returned as-is.

• At least one Sandbox payment test is mandatory to Start Selling.

Commercial Environment

• The actual payment screen shown to real users.

• Testing in this environment triggers real payments for the selected item, so proceed with caution.

• Cancellation is available in the Payment Test History menu.
