NOTIFICATION - Update Vantiv Credit Authorization URL endpoint in PARPOS settings for all locations by 9/15/2026
Update - We are continuing to investigate this issue.
Aug 20, 2026 - 11:27 PDT
Investigating - Dear Valued Customer,

Upcoming scheduled maintenance notice.

Worldpay / Vantiv has migrated to a new Certificate Authority provider. The affected customers would require updating their Vantiv PARPOS Credit Authorization URL endpoint in POS settings.

Previous Address: https://prod.ssl53.com/AUTH
New Address: https://prod.protectedtransactions.com/AUTH

The changes must be updated for all locations by September 15, 2026 to avoid payment failures. This configuration change will trigger a changeset publish and register restart.

PAR also recommends that customers remove legacy MSR configurations from their systems if they are no longer in use, as this will substantially improve operational efficiency and reduce unnecessary processing during end-of-day.

Please ensure network connectivity is up to date for all sites to properly download and install software updates. PAR POS Network Connectivity: https://cdn.parpos.com/en/docs/PAR_POS_Network_Connectivity_Requirements_All_In_One.pdf

If you have additional questions, please contact your PAR POS representative or email us at PaymentServices@Partech.com.

Thank you,

PAR Payment Services Support Team

Update - We are continuing to monitor for any further issues.
Aug 01, 2025 - 12:09 PDT
Monitoring - Support for PAR POS on Legacy Windows Versions has ended. For questions or assistance, please contact your PAR representative directly.

Original notification:
Effective July 31, 2025, we will no longer support PAR POS on terminals and KDS hardware running:

- Windows 10 2015 LTSB
- Windows 7
- Windows 8

These versions do not support Microsoft .NET Core, which is essential for future features and integrations. Upgrading to a supported Windows version ensures uninterrupted service and access to the latest functionality, including the Brink in-store API, which provides real-time data access in-store, regardless of internet connectivity.

Deployment of PAR POS 5.16r3 for Admin20 on 9/9 at 10:30 PM Pacific Sep 9, 2026 22:30 - Sep 10, 2026 00:30 PDT

To prepare for your upgrade, please review PAR POS 5.16r3 resources:
https://cdn.parpos.com/5.16r3ReleaseInformation.html

PAR POS 5.16r3 requires Microsoft .NET Framework 4.7.2 or higher. To help avoid upgrade delays or failures, please verify that .NET Framework 4.7.2 is installed on all terminals before upgrade night.

Please note: Microsoft does not support .NET Framework 4.7.2 on:
• Windows 10 version 1507 (build 10240)
• Windows 10 version 1511 (build 10586)

These operating systems are therefore not supported for PAR POS 5.16r3 and may fail during or after upgrade.

NOTIFICATION - Important Notice for Integrators and Partners: PAR has scheduled Cloudflare maintenance for Admin7 on 9/2 at 10:30 PM PST
Completed - The scheduled maintenance has been completed.
Aug 27, 23:46 PDT
Scheduled - PAR has scheduled a Cloudflare migration maintenance for Admin7 on 9/2 at 10:30 PM PST.

During the maintenance window, customers may experience brief periods of increased latency when accessing the Admin Portal or API endpoints. No prolonged service interruption is expected. We will provide an update once maintenance is complete.

Important Notice for Integrators and Partners:
As part of this maintenance, PAR is implementing updates to our SSL certificate configuration. These updates introduce additional trusted Certificate Authorities (CAs) and result in a change to the certificate chain and trust path used across PAR POS platforms. While existing documentation focuses primarily on in‑store POS environments, these SSL certificate changes also apply to API integrations. Integrations that currently function may encounter connectivity issues if the appropriate root and intermediate certificates are not trusted within partner applications or infrastructure.

PAR platforms utilize a combination of Certificate Authorities, including:
- AWS Certificate Authority
- ssl.com
- Cloudflare Certificate Authorities (including ssl.com–issued certs via Cloudflare)


Required Integrator Action (Strongly Recommended):
All integrators are strongly recommended to validate SSL/TLS connectivity prior to the maintenance window by testing against PAR’s APIINT (integration test) endpoints. These endpoints represent PAR’s two primary certificate authority paths and will help confirm compatibility with the updated trust chain. Successful testing indicates that your integration should continue to function as expected following maintenance.
