# create_folder

Source: https://modulify.ai/docs/api/folders/create-folder

Creates a folder in a workspace to group sites in the dashboard.

- Title: Create a folder
- Scope: `sites:write`
- Access: Makes changes
- Endpoint: `POST /v1/create_folder`

A folder only ever holds sites from its own workspace, and a site sits in at most one. Creating a folder does not move anything into it, which is what `move_sites_to_folder` is for. A workspace holds at most 50 folders, after which this is refused.

The slug is derived from the name with a random three character suffix appended, so it is never exactly the name. Read it back from the response, or set it with `update_folder_slug`. See [Folders](https://modulify.ai/docs/projects/folders#create-a-folder).

## Request

Call it with a `POST` to `https://api.modulify.ai/v1/create_folder`, sending the inputs below as a JSON object. The token needs the `sites:write` scope.

It makes changes, so send an [Idempotency-Key](https://modulify.ai/docs/api/idempotency) header whenever you might retry it. A retry with the same key gets the first answer back instead of running again.

```bash
curl -X POST https://api.modulify.ai/v1/create_folder \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"workspaceId":"WORKSPACE_ID","folder_name":"FOLDER_NAME"}'
```

Over MCP, the same method is the [create_folder tool](https://modulify.ai/docs/mcp/folders/create-folder).

## Inputs

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `workspaceId` | string | Yes | The workspace to create it in. |
| `folder_name` | string | Yes | The folder name, 2 to 84 characters. |

## Response

Every call answers with the [JSON envelope](https://modulify.ai/docs/api/requests-and-responses#the-response) of `success`, `message`, `data`, `code` and `version`. `data` holds the result described above, and on a method that returns a total, `count` carries it. The [response headers](https://modulify.ai/docs/api/requests-and-responses#headers-on-every-method-call) carry the call's `X-Request-Id` and what is left of your per-minute budget in `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset`. [Errors](https://modulify.ai/docs/api/errors) explains every status code a call can answer with.
