ICA certificate chain selection for public OV and EV flex certificates

We are happy to announce that public OV and EV certificates with flex capabilities now support Intermediate CA certificate chain selection.

You can add an option to your CertCentral account that enables you to control which DigiCert ICA certificate chain issues your public OV and EV "flex" certificates.

This option allows you to:

  • Set the default ICA certificate chain for each public OV and EV flex certificate.
  • Control which ICA certificate chains certificate requestors can use to issue their flex certificate.

Configure ICA certificate chain selection

To enable ICA selection for your account, contact your account manager or our Support team. Then, in your CertCentral account, on the Product Settings page (in the left main menu, go to Settings > Product Settings), configure the default and allowed intermediates for each type of OV and EV flex certificate.

For more information and step-by-step instructions, see ICA certificate chain option for public OV and EV flex certificates.


DigiCert Services API support for ICA certificate chain selection

In the DigiCert Services API, we made the following updates to support ICA selection in your API integrations:

  • Created new Product limits endpoint
    Use this endpoint to get information about the limits and settings for the products enabled for each division in your account. This includes ID values for each product's default and allowed ICA certificate chains.
  • Added support for ICA selection to public TLS OV and EV flex certificate order requests
    After you configure allowed intermediates for a product, you can select the ICA certificate chain that should issue your certificate when you use the API to submit an order request.
    Pass in the ID of the issuing ICA certificate as the value for the ca_cert_id parameter in the body of your order request

Example flex certificate request:

We updated the OV and EV SSL/TLS certificate order forms, adding a new DCV verification method dropdown. Now, when ordering OV and EV certificates, you can select the DCV method you want to use to validate the new domains on the order. See our Order your SSL/TLS certificates instructions.

Note: The selected DCV method applies to all unvalidated domains on the order. After submitting the order, you can change the DCV method per domain on the certificate's Order details page. See our Demonstrate control over domains on a pending certificate order instructions.


We updated the domain pre-validation forms, consolidating the OV and EV certificate validation options. Now, when pre-validating a domain, use the new unified domain validation option—OV/EV Domain Validation*. See our Domain pre-validation: Domain control validation (DCV) methods instructions.

Note*: The domain control validation (DCV) methods for OV and EV certificates are the same (verification email, DNS TXT, etc.). The only difference between them is how long the domain validation is valid for. For OV SSL certificates, domains will need to be revalidated every 825 days (approximately 27 months). For EV SSL certificates, domains will need to be revalidated every 13 months.
