Update a materialization schedule for a workbook element (Beta)

This endpoint updates the schedule cadence and/or timezone of an existing materialization schedule for an element in a workbook. For more details on materialization, see [Materialization](https://help.sigmacomputing.com/docs/materialization). **Beta**: This documentation describes a public beta feature and is subject to the [Beta features](/docs/sigma-product-releases#beta-features) disclaimer. ### Usage notes - Retrieve the **workbookId** by calling the [/v2/workbooks](https://help.sigmacomputing.com/reference/list-workbooks) endpoint. - Retrieve the **elementId** by calling the [/v2/workbooks/{workbookId}/elements](https://help.sigmacomputing.com/reference/list-workbook-elements) endpoint. - [Write access](https://help.sigmacomputing.com/docs/set-up-write-access) must be enabled on your connection. - To perform this operation, you must use API credentials owned by a user assigned to an account type with the **Schedule materializations** permission. - The workbook element must already have a materialization schedule. To create one, call the [/v2/workbooks/{workbookId}/elements/{elementId}/materializationSchedules](https://help.sigmacomputing.com/reference/create-materialization-schedule) endpoint.
