ACTION REQUIRED: Upcoming certificate expiry for callback service for tsysapi.arcot.com/callback/api/v1/update-txn

The maintenance is now complete. Thanks for your patience.

The tsysapi.arcot.com URL certificate expires on 21 April 2023. To ensure the continued operation of secure API connection using callback service certificate the following steps must be completed to trust the new certificate. These steps must be completed by 07 April 2023 to ensure service continuity after Arcot installs the renewed certificate at 0500 GMT on 11 April 2023 .

To obtain the certificates, follow the link to our knowledge base https://knowledge.broadcom.com/external/article?articleId=260608 and download the file listed 1677221471370__tsysapi_arcot_com_370013691.zip.

This affects you, as you connect to our service to update the status of your Out Of Band (OOB) / In-App authentication transactions. The root and intermediate remain unchanged and only a new leaf certificate has been issued. If you already have the root and/or intermediate trusted then there is no action required.

Arcot’s recommendation is to trust the Root and Intermediate certificates only. If you are required to also trust the Leaf certificate, please ensure that all three certificates are loaded into your Trust Store. To avoid impact to service, the existing certificates must not be removed until they have expired. Arcot will also monitor the transactions post switching of the production traffic and notify if required.

As an acknowledgement, please inform Broadcom CSM/PM or raise a support case that :

1. You have received the renewed certificates properly (as sometimes they are corrupted).
2. The action required at your end with an ETA so we can line up downstream plans accordingly

Improving our Certificate Lifecycle Management is a strategic area of focus for Arcot and we are investing heavily to ensure that more advanced notice is provided for future changes.

If you have any questions, kindly create a case through the Broadcom Support Portal (https://support.broadcom.com/) .

Sincerely, Arcot Support Team
