In DigiCert® Account Manager, set up API access for a regular or service user with at least the following two user roles:
CA Manager: Read only
Trust Lifecycle Manager: Import manager
For the best management options, use DigiCert® CA Manager to import the issuing CA and configure Certificate Revocation List (CRL), Authority Information Access (AIA), and Online Certificate Status Protocol (OSCP) parameters to match what's in the certificates.
When this prerequisite is met, the uploaded certificates are automatically assigned the Imported seat type license.
See Prerequisites and workflow to use "Imported seat" licenses for details about how to set this up.
