# Publish a version of a page

`POST https://studio.grid82.app/v1/apps/{appId}/pages/{pageId}/publish`

Point the page to a built version: the latest by default, or an earlier one via `version`.

Saves always build; publishing does not compile, cannot fail on code, and shows the same result as the preview. Refuse versions that did not build, with the reason. Use `files` when the caller supplies its own build.

Requires the `pages:write` scope. Operation `pages.publish`. MCP tool `pages_publish`. CLI: `grid82 pages publish` (`npx grid82`).
