# Create a workspace ruleset

> Create a workspace ruleset, as for a repository, plus conditions.repository: which of the workspace's repositories it holds in (include and exclude name patterns, visibility, topics).

<div class="g1t-endpoint"><span class="g1t-method" data-method="post">POST</span><code>/workspaces/{workspace}/rulesets</code></div>

Owners only.

`conditions.repository` chooses the repositories it holds in; left out, every repository of the workspace.

- **Authentication:** Required. Send an [access token](/reference/api/#authentication) as `Authorization: Bearer`.
- **MCP tool:** [`workspace`](/reference/mcp/#workspace) with `action` `create_ruleset`, and the same inputs
- **Scope:** An access token needs [`workspace:admin`](/guides/authentication/#scopes).

## Path parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `workspace` | string | Yes | The workspace's slug, e.g. "flagon-io". |

## Body parameters

Send a JSON object. Names are `snake_case`, as in responses; the `camelCase` spelling is accepted too.

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `ruleset_name` | string | No | What people call it, at most 100 characters. A ruleset as exported names it `name`, which is read too. |
| `enforcement` | string | No | active: its rules hold. evaluate: nothing is refused, and what would have been is recorded. disabled: kept, not evaluated. Default active. One of `active`, `evaluate`, `disabled`. |
| `target` | string | No | What its name conditions match. Default branch. One of `branch`, `tag`. |
| `conditions` | object | No |  |
| `conditions.ref_name` | object | No | Which branches or tags: include and exclude, each a list of fnmatch patterns (* within a path segment, ** across them), ~DEFAULT_BRANCH or ~ALL. |
| `conditions.ref_name.include` | array of strings | No |  |
| `conditions.ref_name.exclude` | array of strings | No |  |
| `conditions.repository` | object | No | Which of the workspace's repositories: include and exclude name patterns (or ~ALL), visibility (any, public, private) and topics (any of). |
| `conditions.repository.include` | array of strings | No |  |
| `conditions.repository.exclude` | array of strings | No |  |
| `conditions.repository.visibility` | string | No | One of `any`, `public`, `private`. |
| `conditions.repository.topics` | array of strings | No |  |
| `bypass_actors` | array of objects | No | Who it does not hold for. Nobody bypasses unless listed, g1t included. kind role takes read, triage, write, maintain, admin (that role or higher) or owner; team its slug or workspace/slug; user a username; token a token id, or workspace for any of the workspace's tokens; g1t no value. mode always (pushes and merges) or pull_requests (merges only; a person merging asks to, with bypass_rules). |
| `bypass_actors[].kind` | string | Yes | One of `role`, `team`, `user`, `token`, `g1t`. |
| `bypass_actors[].value` | string | No |  |
| `bypass_actors[].mode` | string | No | One of `always`, `pull_requests`. |
| `rules` | array of objects | No | Its rules. Each: type, parameters (left-out parameters take their defaults) and applies_to (everyone, agents or people). See the Rules guide for every type's parameters. |
| `rules[].type` | string | Yes |  |
| `rules[].parameters` | object | No |  |
| `rules[].applies_to` | string | No | One of `everyone`, `agents`, `people`. |

## Errors

A failed request answers with one of these statuses and a body like `{"error": {"code": "not_found", "message": "Repository not found."}}`. See [errors](/reference/api/#errors).

| Status | Code | When |
| --- | --- | --- |
| 401 | `unauthenticated` | A token is required, or the one sent is not valid. |
| 403 | `forbidden` | The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository. |
| 404 | `not_found` | It does not exist, or you cannot see it. |
| 409 | `conflict` | The request conflicts with the current state. |
| 422 | `invalid` | The input is not valid. `message` says which field and why. |
