# Publish prompt draft version

> Publish one reviewed prompt draft version.

Publishes one exact prompt draft version and makes its three prompt arrays the
agent's active configuration.

Before calling this route, fetch the version with
[Get prompt draft version](/en/api-reference/get-prompt-draft-version), compare
it with [Get prompts](/en/api-reference/get-prompts), and obtain explicit
confirmation for that agent and version.

<Warning>
  Publishing changes live agent behavior. A draft becomes stale when the
  published prompt changes after the draft was created. Fini rejects stale
  drafts instead of overwriting the newer configuration.
</Warning>
