Create Plugin Version

$ ant beta:organization:plugins:versions create
POST/v1/organizations/plugins/{plugin_id}/versions

Add a version to an organization-owned Plugin by uploading the new version's files; it becomes the version served to members unless the Plugin's served version has been pinned.

The upload is the same multipart/form-data as creating a Plugin: the version's files (files, each part sent as files[]) and optional release_notes. The uploaded manifest's name must equal the Plugin's name. Returns the stored version; read the Plugin back to see which version it serves.

Only a Plugin in a manual marketplace takes uploads; a Plugin synchronized from a repository gets its versions from the repository. When the Plugin is in the organization's library marketplace, a version that adds a skill with the name of an organization skill (a skill an administrator uploaded for the whole organization in claude.ai) is refused with a 409: error_code skill_name_taken, with that name in details.skill_name. A 503 with error_code registration_pending means the version was stored but is not yet usable; a later version create on the Plugin completes it.

For a worked example, see Create a version in the Plugins API guide.

Accepted credentials: an Admin API key with the write:plugins scope.

Every request must include the beta header anthropic-beta: ce-plugins-2026-09-01. A request without it returns 404, exactly as if the endpoint did not exist. The Plugins API is in beta and is available to Claude Enterprise organizations only. It is not available to Claude Platform (Claude Console) organizations, or to organizations with HIPAA readiness enabled.

Parameters
--plugin-id: string⁠Path parameter

ID of the Plugin (prefixed plugin_).

--file: array of string

The version's files: one part per file, the part's filename being the file's path within the Plugin (for example skills/review-pr/SKILL.md), or a single .zip or .plugin archive holding them all. On the wire each part is named files[], and a part named plain files is not read; with cURL, -F 'files[]=@SKILL.md;filename=skills/review-pr/SKILL.md'. The files must include the manifest, .claude-plugin/plugin.json.

--release-notes: optional string

Release notes stored with the version and shown in its version history in claude.ai; up to 5,000 characters.

maxLength5000
--beta: optional array of AnthropicBeta⁠Header parameter

This endpoint is in beta: requests must send ce-plugins-2026-09-01 in this header.
