With over 1,000 APIs across DigiCert CertCentral® and DigiCert® ONE, organizations can automate enterprise-scale machine identity management, certificate lifecycle operations, secure code signing, private PKI infrastructure, and device trust workflows at scale. All products share the same authentication model, error semantics, rate limits, and versioning strategy.

Most products use v1 APIs. Device Trust uses v1 to v4 and a slightly different versioning path (see Base URL pattern). Always check the most recent API reference before coding hard-wired paths.
