Investigating - Dear PAR Pay Customer,
As the much-awaited holiday season quickly approaches, we wanted to inform you of our holiday change freeze periods and timelines.
What is a “change freeze” and how does it impact you?
A change freeze allows our employees to enjoy time with their families during the holiday season, as well as take care of routine maintenance that is vital to keeping your restaurant running smoothly. Rest assured that day-to-day operations will not be impacted; however, we will not be able to honor change requests until after the freeze period.
What type of requests are put on hold until after the change freeze?
• Onboarding and Credential Testing for New Stores
• Credit Card Updates (builds, operating systems)
• Artwork Downloads
• Gift Card Bin Ranges (if applicable)
We’re still here for you -- our support desk will remain open 24/7 during this period. We will continue to ship devices during this time as well.
Thanksgiving Change Freeze Dates
• November 16 - December 1
• Please note: any change requests (listed above) received after November 13th will be managed after the freeze, on December 2nd.
Christmas Change Freeze Dates
• December 14 - January 3
Please note: any change requests (listed above) received after December 11th will be managed after the freeze, on January 4th, 2027.
If you have any questions or concerns, please do not hesitate to reach out to your PAR point of contact or to our support team at 800-403-9027.
We appreciate your understanding and support!

Investigating - Dear Valued Customer,
We are re-sending the below update regarding Worldpay / Vantiv maintenance.
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,
