On April 12, 2023 (10pm PDT)/April 13, 2023 (5:00am GMT) we will be performing networking updates for Production, beginning 10:00pm Pacific. This update will remove support for CBC ciphers and add support for TLS v1.3.
ECDHE GCM are preferred ciphers to be used at this time. This change will only impact portal/interfaces for Authorize.net and not API integrations. There will be a separate update for our API endpoints at a later date.
Portal users will need to make sure to use updated/modern web browsers.
For more information, please see our support article: Authorize.net TLS and Cipher Support
Please do not hesitate to contact the Authorize.net support team if you have any questions or concerns.
