list-calendar-view-delta
Synchronize calendar events within a time window by retrieving only changes (additions, deletions, updates) since last sync. Supports delta links for incremental updates and expands recurring events to individual occurrences.
Instructions
Get a set of event resources that have been added, deleted, or updated in a calendarView (a range of events defined by start and end dates) of the user's primary calendar. Typically, synchronizing events in a calendarView in a local store entails a round of multiple delta function calls. The initial call is a full synchronization, and every subsequent delta call in the same round gets the incremental changes (additions, deletions, or updates). This allows you to maintain and synchronize a local store of events in the specified calendarView, without having to fetch all the events of that calendar from the server every time.
đź’ˇ TIP: Incremental sync of events within a time window. Required query params on first call: startDateTime, endDateTime (ISO 8601). Returns events in the window plus @odata.deltaLink; subsequent calls with that link return only changes. Expands recurring events to individual occurrences (unlike list-calendar-events-delta which returns the series master). Use this for calendar UIs showing a week/month view.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| skip | No | Items to skip for pagination. Not supported with $search. | |
| count | No | Set true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains(). | |
| expand | No | Expand related entities | |
| filter | No | OData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search. | |
| search | No | KQL search query — wrap value in double quotes. Cannot combine with $filter. | |
| select | No | Comma-separated fields to return, e.g. id,subject,from,receivedDateTime | |
| orderby | No | Sort expression, e.g. receivedDateTime desc | |
| endDateTime | Yes | The end date and time of the time range in the function, represented in ISO 8601 format. For example, 2019-11-08T20:00:00-08:00 | |
| fetchAllPages | No | Follow @odata.nextLink and merge up to 100 pages into one response. Can return enormous payloads—only when the user explicitly needs a full export. Prefer a small $top first, then paginate or narrow with $filter/$search. | |
| startDateTime | Yes | The start date and time of the time range in the function, represented in ISO 8601 format. For example, 2019-11-08T20:00:00-08:00 | |
| includeHeaders | No | Include response headers (including ETag) in the response metadata | |
| excludeResponse | No | Exclude the full response body and only return success or failure indication |
