CertCentral Services API: Order code signing certificates with a custom expiration date

In the CertCentral Services API, we updated the Order code signing certificate endpoint to support custom expiration dates. Now, when you order a code signing certificate, you can use the custom_expiration_date request parameter to set the exact date the certificate will expire.

Example request body:

Code signing custom expiration date parameter


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.

For DigiCert Services API documentation, see CertCentral API.


We added a new Order Management - List Order Reissues API endpoint that allows you to view all the reissue certificates for a certificate order. See the List order reissues endpoint.


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.
