With Opn Payment, you can check a series of operations such as billing, refunds, and chargebacks in a test environment as long as you have a test account, even before applying for merchant screening.

In the test environment, you can use the test card number (Visa or Mastercard) specified by each card brand.

Test charging for JCB and American Express is available only upon request. Please contact customer support at support@opn.ooo if you would like to make a request.

Note: Due to system requirements, when Japanese merchants test charge JCB, the Visa and Mastercard fee rates are deducted from the original fee.

Please note that there are no test credit card numbers for Diners Club and Discover cards. Please try other card brands for test charging.
