M365 Changelog: Planner Scope Based Diff Sync API Update

MC504328 · – Delta Query enables applications to discover newly created, updated, or deleted entities without performing a full read of the target resource with every request.

The Delta Sync method allows your application to track changes to objects that the user can access from within Planner over time.

When this will happen

• The planner team will start rolling out the update by mid-February.
• The roll out is expected to be completed by end of February and associated documentation will be made available as part of the public Graph API.  

As part of Planner Delta Sync Update, Microsoft will be making a method call available which will narrow the scope of sync requests to match individual queries. Members added to a plan will have access to new and recent changes to the plan. Diff Sync API provides you with the initial state and follow up with delta.
