PAR has scheduled a Cloudflare migration maintenance for Admin25 on 10/14 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. - https://api-apiint.parpos.com/Sales.svc - https://api-apiint.brinkpos.net/Sales.svc
In addition, check for the following: Certificate pinning - If your integration pins to a specific certificate or thumbprint, it will break as once Cloudflare is in front, the certificate presented to the client changes. Confirm that the code either does not pin a certificate, or is updated to pin to the new Cloudflare-issued certificate. TLS version and SNI - Cloudflare requires TLS 1.2 or higher, and requires SNI (Server Name Indication) in the handshake. If the client is on an older TLS version or an old library that skips SNI, the connection will fail.
Support: If you encounter issues during testing or require additional technical details, please contact your PAR representative or email support.PARPOSsoftware@partech.com.
We appreciate your partnership and proactive validation to ensure uninterrupted service.
