Transaction gateway handling subsequent-in-series Mastercard authorizations suboptimal

Update timeline

1. resolved Jun 03, 2021, 01:55 PM UTC

   An update to gateway.clearhaus.com that was rolled out shortly after 2021-06-02T13:50:00Z and rolled back by 2021-06-03T09:38:00Z had a regression for the processing of subsequent-in-series Mastercard authorizations resulting in a slightly increased rate of declines (with status code 40416). The vast majority of such authorizations processed in the above-mentioned interval was processed without properly marking the authorization as “exempted for SCA”, and a few issuers happened to decline as a result of the missing indication. Approximately 1,300 such authorizations were declined during the period due to this regression. These merchant-initiated authorizations may be retried by the merchant or the PSP, so we advise merchants or PSPs to retry subsequent-in-series Mastercard authorizations that were declined with status code 40416 during the above-mentioned period. Please be aware that PSPs may already have systems in place to auto-retry subsequent-in-series authorizations. We apologize for the inconvenience this has caused! If you have any questions, please feel free to reach out to us.
