Transactions for the period 2021-10-06 19:00:00 – 2021-10-07 18:59:59 UTC were cleared twice.
During transaction clearing, already cleared transactions were cleared again. All transactions (captures, refunds and credits) processed between 2021-10-06 19:00:00 UTC and 2021-10-07 18:59:59 UTC were affected for both Visa and Mastercard, with the exception of Visa credits.
If you suspect your cardholders are impacted by this and want to be certain, please reach out to Clearhaus via email to email@example.com and include your Merchant ID (you can find it in the upper right for instance when seeing details for a transaction); then we will respond with a list of impacted transactions.
