Hi,
API's are used to query and interact with Denodo Platform elements, it cannot modify data or metadata of the data sources.
In case if you are creating data sources for SOAP webservices, that can be altered. Please refer to [Alter Data Source Web Service](https://community.denodo.com/docs/html/browse/latest/en/vdp/vql/generating_wrappers_and_data_sources/creating_data_sources/data_sources_for_web_services#syntax-of-the-alter-datasource-ws-statement:~:text=Syntax%20of%20the%20ALTER%20DATASOURCE%20WS%20statement%C2%B6) section of [Data Sources for SOAP Web Services](https://community.denodo.com/docs/html/browse/latest/en/vdp/vql/generating_wrappers_and_data_sources/creating_data_sources/data_sources_for_web_services#syntax-of-the-alter-datasource-ws-statement) for more information.
Hope this helps.
