【Wix】Using KOMOJU Test Payments (Sandbox) – KOMOJU Help Center

Due to changes in Wix's specifications, you cannot use test payments via KOMOJU's Test mode (sandbox) on the Wix platform.

NOTE: Important Note on Testing in Live Mode
If you process a payment in Live mode to verify the actual payment flow, any transaction that reaches the "Paid" status will be subject to KOMOJU's transaction fees, even if you refund it later.

To use the actual payment functionality (Live mode), you must first pass the merchant screening process. Access and usage in Live mode will be sequentially enabled for payment methods that have completed this screening.

Next Steps:
To start or verify payments in the production environment, please check your merchant application status from the target "Settings" or "Application" screen on your KOMOJU dashboard.
