How to Entrust to DigiCert SSL Certificate Migration of Authorize.net?
I've received this message as our website is having issues with our payment provider: 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.
