--- title: Create Plugin Version url: https://platform.claude.com/docs/en/api/csharp/beta/organization/plugins/versions/create --- # Create Plugin Version `BetaPluginVersion Beta.Organization.Plugins.Versions.Create(parameters, cancellationToken = default)` **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](https://platform.claude.com/docs/en/manage-claude/plugins-api?sdk_languages=csharp#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 - `VersionCreateParams parameters` - `required string pluginID` (path parameter) ID of the Plugin (prefixed `plugin_`). - `required IReadOnlyList files` 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`. - `string releaseNotes` Release notes stored with the version and shown in its version history in claude.ai; up to 5,000 characters. maxLength: 5000 - `IReadOnlyList betas` (header parameter) This endpoint is in beta: requests must send `ce-plugins-2026-09-01` in this header. - `MessageBatches2024_09_24("message-batches-2024-09-24")` - `PromptCaching2024_07_31("prompt-caching-2024-07-31")` - `ComputerUse2024_10_22("computer-use-2024-10-22")` - `ComputerUse2025_01_24("computer-use-2025-01-24")` - `Pdfs2024_09_25("pdfs-2024-09-25")` - `TokenCounting2024_11_01("token-counting-2024-11-01")` - `TokenEfficientTools2025_02_19("token-efficient-tools-2025-02-19")` - `Output128k2025_02_19("output-128k-2025-02-19")` - `FilesApi2025_04_14("files-api-2025-04-14")` - `McpClient2025_04_04("mcp-client-2025-04-04")` - `McpClient2025_11_20("mcp-client-2025-11-20")` - `DevFullThinking2025_05_14("dev-full-thinking-2025-05-14")` - `InterleavedThinking2025_05_14("interleaved-thinking-2025-05-14")` - `CodeExecution2025_05_22("code-execution-2025-05-22")` - `ExtendedCacheTtl2025_04_11("extended-cache-ttl-2025-04-11")` - `Context1m2025_08_07("context-1m-2025-08-07")` - `ContextManagement2025_06_27("context-management-2025-06-27")` - `ModelContextWindowExceeded2025_08_26("model-context-window-exceeded-2025-08-26")` - `Skills2025_10_02("skills-2025-10-02")` - `FastMode2026_02_01("fast-mode-2026-02-01")` - `Output300k2026_03_24("output-300k-2026-03-24")` - `UserProfiles2026_03_24("user-profiles-2026-03-24")` - `UserProfiles2026_08_18("user-profiles-2026-08-18")` - `UserProfiles2026_09_04("user-profiles-2026-09-04")` - `AdvisorTool2026_03_01("advisor-tool-2026-03-01")` - `ManagedAgents2026_04_01("managed-agents-2026-04-01")` - `CacheDiagnosis2026_04_07("cache-diagnosis-2026-04-07")` - `Dreaming2026_04_21("dreaming-2026-04-21")` - `ThinkingTokenCount2026_05_13("thinking-token-count-2026-05-13")` - `ServerSideFallback2026_06_01("server-side-fallback-2026-06-01")` - `ServerSideFallback2026_07_01("server-side-fallback-2026-07-01")` - `FallbackCredit2026_06_01("fallback-credit-2026-06-01")` - `FallbackCredit2026_07_01("fallback-credit-2026-07-01")` - `AgentMemory2026_07_22("agent-memory-2026-07-22")` - `MidConversationToolChanges2026_07_01("mid-conversation-tool-changes-2026-07-01")` - `Compact2026_01_12("compact-2026-01-12")` - `ComputerUse2025_11_24("computer-use-2025-11-24")` - `McpTunnels2026_06_22("mcp-tunnels-2026-06-22")` - `StructuredOutputs2025_11_13("structured-outputs-2025-11-13")` - `TaskBudgets2026_03_13("task-budgets-2026-03-13")` - `ThinkingDisplayUpdates2026_08_18("thinking-display-updates-2026-08-18")` - `CEUserManagement2026_07_13("ce-user-management-2026-07-13")` - `MidConversationOutputConfig2026_07_01("mid-conversation-output-config-2026-07-01")` - `ThinkingBindingControls2026_08_01("thinking-binding-controls-2026-08-01")` - `MidConversationSystemClearAt2026_08_21("mid-conversation-system-clear-at-2026-08-21")` - `Compact2026_09_04("compact-2026-09-04")` - `InlineTools2026_09_15("inline-tools-2026-09-15")` - `McpClient2026_09_15("mcp-client-2026-09-15")` - `CEPlugins2026_09_01("ce-plugins-2026-09-01")` - `SpendLimitReads2026_09_26("spend-limit-reads-2026-09-26")` - `TelemetryDestinations2026_08_11("telemetry-destinations-2026-08-11")` - `Webhooks2026_10_07("webhooks-2026-10-07")` ## Returns - `class BetaPluginVersion` - `JsonElement Type = "plugin_version"` Always `plugin_version`. - `required string ID` The version's ID. - `required IReadOnlyList? Components` What the version contains; null when not enumerated. - `required Type Type` The kind of component. - `Agent("agent")` - `Cli("cli")` - `Command("command")` - `Hook("hook")` - `McpServer("mcp_server")` - `Skill("skill")` - `required string? Description` What the component declares about itself; always null for MCP servers, hooks, and CLIs. - `required string Name` The component's name: a skill's, command's or agent's name, an MCP server's key in the manifest, the event a hook runs on, or a CLI's executable. - `required BetaPluginContentScan? ContentScan` This version's content scan; null when it has not been scanned. - `required Assessment? Assessment` The scan's verdict; set only when `status` is `completed`. A `warn` can mean a `fail` that was allowed in claude.ai. - `Fail("fail")` - `Pass("pass")` - `Unknown("unknown")` - `Warn("warn")` - `required string? Reason` The primary mechanism behind a `warn` or `fail`, such as `credential-exposure` or `guardrail-tampering`; a mechanism this API does not yet name reads as `other`. Null on a `pass`, whenever `assessment` is null, and when no mechanism is reported for the verdict. - `required Status Status` `processing` while a scan runs, `completed` when it ran to completion, `errored` when it could not run. Once a scan of the version has completed, `content_scan` describes the newest completed scan, even while a later scan runs. While the scan outcome cannot be read, `status` is `errored` instead. - `Completed("completed")` - `Errored("errored")` - `Processing("processing")` - `required DateTimeOffset CreatedAt` RFC 3339. format: date-time - `required CreatedBy? CreatedBy` Who uploaded this version; null when not recorded. - `class BetaPluginUserActor` - `JsonElement Type = "user_actor"` A member of the organization. - `required string? EmailAddress` The member's email address; may be null, for example when they are no longer a member of the organization. - `required string UserID` The member's User ID. - `class BetaPluginApiActor` - `JsonElement Type = "api_actor"` An Admin API key, in the same form the Compliance API activity feed uses for it. - `required string ApiKeyID` The key's ID. - `required string? Description` The manifest's description; null when it declares none. - `required string? DisplayName` The manifest's display name; null when it declares none. - `required string? ManifestVersion` The manifest's `version`, normalized for display: one leading `v` or `V` is dropped, and the result is returned only if it is 1 to 64 characters, starts with a digit, and uses only ASCII letters, digits, `.`, `+`, and `-`; otherwise `null`. For example, `"v1.4.0"` is returned as `"1.4.0"`, and `"latest"` as `null`. For a synchronized plugin, the `version` of its `marketplace.json` entry can take the place of the manifest's `version`. It is also `null` for a version stored before claude.ai began recording this field (August 2026). - `required string PluginID` The Plugin's ID. - `required Reach? Reach` How far the version reaches: `remote`, `privileged`, `contained`, or `null`, as defined on the Plugin's `reach`. - `Contained("contained")` - `Privileged("privileged")` - `Remote("remote")` - `required string? ReleaseNotes` As supplied with the upload; null when none were supplied. ## Example ```csharp using System; using System.Text; using Anthropic.Models.Beta.Organization.Plugins.Versions; VersionCreateParams parameters = new() { PluginID = "plugin_id", Files = [ Encoding.UTF8.GetBytes("Example data") ], }; var betaPluginVersion = await client.Beta.Organization.Plugins.Versions.Create(parameters); Console.WriteLine(betaPluginVersion); ``` ### Response (200) ```json { "id": "pluginver_01KaZmQpRsTuVwXyZ2b4c6d8", "components": [ { "description": "description", "name": "review-pr", "type": "skill" } ], "content_scan": { "assessment": "warn", "reason": "credential-exposure", "status": "completed" }, "created_at": "2026-03-14T09:26:53.589793Z", "created_by": { "email_address": "user@example.com", "type": "user_actor", "user_id": "user_01WCz1FkmYMm4gnmykNKUu3Q" }, "description": "Reviews pull requests against your team's conventions.", "display_name": "Code Review Helper", "manifest_version": "1.2.0", "plugin_id": "plugin_01JyHfbRkZvD1gW7oTqXc3Ne", "reach": "contained", "release_notes": "Adds a review checklist for database migrations.", "type": "plugin_version" } ```
