Verify a workbook code representation (Beta)

This endpoint validates a workbook code representation without creating or modifying any workbook. It performs the same validation as the [/v2/workbooks/spec](https://help.sigmacomputing.com/reference/create-workbook-spec) endpoint but never persists the result, so you can confirm a representation is valid before creating a workbook from it. **Beta**: This documentation describes a private beta feature and is subject to the [Beta features](/docs/sigma-product-releases#beta-features) disclaimer. ### System and user requirements - To perform this operation, you must use API credentials owned by a user assigned an account type with **Create, edit, and publish workbooks** permission. ### Usage notes - The response `valid` field indicates whether the representation passed validation. When `valid` is `false`, the `errors` array describes each validation failure. - The request body is identical to the [/v2/workbooks/spec](https://help.sigmacomputing.com/reference/create-workbook-spec) endpoint. - No workbook is created and no data is persisted by this endpoint. ### Usage scenarios - **Agentic workflows**: Agents can validate a generated representation before committing it to a create or update operation. - **Automation**: Validate representations in CI or migration tooling before applying them.
