When you process a refund in KOMOJU, it is passed to EC-CUBE via the payment.refunded webhook event. Settlement timing to the customer varies by payment method.
How to Check Refund Status
Before notifying the customer about a refund, confirm on the KOMOJU Dashboard that the refund has actually been completed.
- Open the Transactions page in the KOMOJU Dashboard
- Search for the relevant transaction and open its detail screen
- Check the transaction status
- If it shows "Refunded" or "Partially Refunded," the process is complete
- If there is an error, note the KOMOJU Order ID and contact support
If Webhook Sync Doesn't Reflect on EC-CUBE
If webhooks are configured correctly, a refund processed on the KOMOJU side will automatically reflect on the EC-CUBE side as well.
If it does not reflect, please check whether your webhook configuration has been completed.
Settlement Timing by Payment Method
Credit Card
Refunds are issued back through the credit card, and appear as a negative amount on the customer's card statement.
- Typical timing: 5–10 days on average. Some card issuers may take up to about 2 months
- Crossing a billing cutoff: the original charge is applied first, and the refund (or offset) occurs the following month or later
- Cancelled cards: refunded by an alternative method per the card issuer's policy, such as a bank transfer
The exact settlement date depends on the card issuer's processing. Advise customers to contact their card issuer directly for details.
Mobile Payment
Applies to PayPay, Merpay, Rakuten Pay, au PAY, d payment, etc. Once the refund is processed, it is reflected directly in the balance within each app.
About the Availability of d Payment
d payment will be available starting September 30, 2026. Before that date, payments and refunds via d payment are not available.
- Typical timing: usually reflected within a few hours
The actual timing depends on each app's own specifications.
Convenience Store, Pay-easy, and Bank Transfer
The refund is sent by bank transfer to the account the customer specifies.
- Typical timing: completed within 1 business day if within the financial institution's business hours
- Cases that take longer: 1–2 business days depending on the timing of the request and bank holidays
- Sender name: transfers to the customer's account are made under the name "株式会社KOMOJU" (KOMOJU Co., Ltd.)
