Creates a workflow.

- **Path** `POST https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/workflows`
- **Scope** `workflows:write`
- **Effect** `write` — a successful call changes state.
- **Collection** [workflows](/docs/api/workflows)
- **Query** `workflow_id`, `validate_only`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `parent` | `string` | The parent to create in. Required. |
| `workflow_id` | `string` | The workflow id, the final name segment; the server assigns one when empty. |
| `workflow` | `Workflow` | The workflow to create; only caller-writable fields are read. Required. |
| `validate_only` | `bool` | Validate and return the result without writing anything. |

### Workflow

| Field | Type | What it is |
