Hello Stanislav. Currently, task-related Microsoft Graph API endpoints will not work with Microsoft Planner Premium plans, as they work with their own Plan ID structure. This limitation is further confirmed in the Microsoft Q&A above. Even though the Premium plan offers additional features like goals, sprint functions, and task history, their data is all held in Dataverse and not in the structure you would expect to see with the Basic Planner plan.
To obtain data from a Premium plan programmatically, Microsoft wants developers to utilize Dataverse query options such as:
TDS (Tabular Data Stream) endpoint for SQL-like access
Dataverse Web API for RESTful queries
However, Planner Premium's Dataverse schema is disjointed and not publically documented for users, making it difficult to query directly. Alternatively, as a workaround you could use Power Platform connectors (e.g., Power Automate or Power BI) to engage or visualize Planner Premium data if you have the proper access and licensing permissions.
Best regards,
