Hi @Vishal_Chauhan ,

A 403 Forbidden error generally indicates that you do not have the necessary permissions to perform the requested action. Could you please check and confirm the following info?

• Confirm if your current workspace supports creating Datamarts. Note that Datamarts aren’t supported in EM1/EM2 and EM3 Power BI SKUs: Administration of datamarts (preview) - Power BI | Microsoft LearnEnabling datamarts in the admin portal
• Check if you have relevant permissions in the workspace where the Datamart resides:Control access to datamarts (preview) - Power BI | Microsoft Learn
• Check if you have the sufficient privilege to access the data source which the datamart connect to? Please verify that your data source credentials are correct.

Best Regards
