Understanding SSL Leaf Level Certificates and Yearly Renewals

Authorize.net recommends that your site and applications trust the Root and Intermediate CA SSL certificates rather than the server-level certificate. This method eliminates the need to update or install the latest leaf certificate, which is updated annually before their expiration dates. If your application trusts only the Root and Intermediate level certificates, there is no need to install the certificates attached to this article.

Latest Update:

The most recent update will follow the schedule below, and the most current certificates are attached as of September 2024.

This latest update involves a complete certificate change. For more details, refer to the support article: Entrust to DigiCert SSL Certificate Migration
