We enhanced our SSL/TLS and client certificate product offerings, enabling you to set a custom validity period (in days) when ordering one of these certificates. Previously, you could only choose a custom expiration date.
Custom validity periods start on the day we issue the certificate. Certificate pricing is prorated to match the custom certificate length.
Note: Custom certificate lengths can't exceed the industry allowed maximum lifecycle period for the certificate. For example, you can't set a 900-day validity period for an SSL/TLS certificate.
We enhanced the SSL/TLS and Client certificate endpoints to include a new validity_days parameter that allows you to set the number of days that the certificate is valid for.
Parameter Priority Note: If you include more than one certificate validity parameter in your request, we prioritize the certificate validity parameters in this order: custom_expiration_date > validity_days > validity_years.

Enhancements made to client certificates. When ordering a client certificate (Premium, Email Security Plus, Digital Plus, and Authentication Plus), you may now include a Custom Expiration Date for your client certificates.
Previously when ordering a client certificate, you were only able to select 1, 2, or 3 years for the certificate's validity period.
