Use this endpoint to list available validation types for domains.


> **Info**
>
> **Domain validation reuse periods will continue to decrease**
>
> Due to industry-wide changes, the domain validation reuse period will continue to shorten over time. Starting February 24, 2026, the maximum domain validation reuse period will be 199 days. For existing pre-validated domains, the new expiration date must be calculated as the last validation date + 199 days. By 2029, the domain validation reuse period will be reduced to 10 days. For more information, see <a href="https://knowledge.digicert.com/alerts/domain-validation-reuse-changes-in-2026" target="_blank" rel="noopener noreferrer">Domain validation reuse changes in 2026</a>.
