List columns for a report element

This endpoint retrieves a list of columns associated with a specific element within a report. It provides metadata about each column, such as name and formula, which can be essential for understanding the data structure and for further data manipulation or analysis. ### Usage notes - Retrieve the **reportId** by calling the [/v2/reports](https://help.sigmacomputing.com/reference/list-reports) endpoint. - Retrieve the **elementId** by first calling the [/v2/reports/{reportId}/pages](listreportpages) endpoint, then calling the [/v2/reports/{reportId}/pages/{pageId}/elements](listreportpageelements) endpoint. - The element that you request must be a data element, such as a table, pivot table, or visualization. Requesting a UI or control element returns an error. ### Usage scenarios - **Data exploration:** Helps users explore the data structure of a report element, facilitating deeper analysis and understanding. - **Integration tasks:** Useful for developers integrating Sigma with other tools that need to know the data structure to map data accurately. ### Best practices - Validate the **elementId** to make sure it corresponds to the correct report element before querying. - Leverage this endpoint when setting up interfaces that require specific knowledge about the data structure.
