Digicert TLS Certificate Renewals
Stating today July 28th, 2025, Authorize.net is renewing their Digicert TLS certificates that applications and websites use to communicate with our systems. This change will impact both browser-based and server-to-server interactions.
Scenarios Requiring Action:
Users whose applications or websites pin the leaf certificate will need to update their settings.
Users whose applications or websites pin to the CAs will need to update their pins.
We advise reaching out to your solution providers, developers, or website hosts for assistance with these changes if they are needed. We also advise going forward that solutions/web hosts DO NOT pin the Leaf certificate as these will be frequently changing to adhere to security requirements.
Schedule:
Sandbox: July 28th, 2025
Production: August 4th - August 21st, 2025
