Investigating
Eway is currently experiencing an intermittent disruption to our Gateway API payment service due to an issue with one of our upstream providers. As a result, some transactions may fail with a dishonour response code ‘W9’ . This issue is primarily impacting New Zealand gateway merchants using acquiring banks connected via the Worldpay/Paymark integration. Affected financial institutions include BNZ, ASB, ANZ, Westpac NZ, NAB, and National NZ.
Our team is actively working with the upstream vendor to resolve the issue and will provide further updates as soon as they become available. If you have any urgent queries regarding this service interruption, please contact us on: AU: 1800 10 6565 NZ: 0800 392 947
We appreciate your patience and apologise for any inconvenience caused.
