list-planner-task-messages
Read-only

Get messages from a Planner task's chat, distinct from legacy comments. Each message includes content, author, timestamp, mentions, and reactions.

Instructions

[beta] Retrieve a list of plannerTaskChatMessage objects associated with a plannerTask.

💡 TIP: Lists messages in a Planner task's chat — the modern Planner 'task chat', distinct from the legacy conversationThreadId comments (which live in the M365 group conversation thread). Each message has id, content (HTML), createdBy, createdDateTime, mentions, reactions. BETA Graph API: subject to change; delegated work/school accounts only — no application permissions, no personal Microsoft accounts, global cloud only (not GCC/DoD/21Vianet).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
topNoPage size (Graph $top). Start small (e.g. 5–15) so responses fit the model context; raise only if needed. Use $select to return fewer fields per item. For more rows, use @odata.nextLink from the response instead of a very large $top.
skipNoItems to skip for pagination. Not supported with $search.
countNoSet true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains().
expandNoNavigation properties to inline, e.g. attachments on a message or event. Only navigation properties can be expanded: expanding a non-navigation property such as a message body fails with "Parsing OData Select and Expand failed", and an unsupported value may be ignored rather than reported. Request ordinary fields with $select instead.
filterNoOData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search.
searchNoKQL search query — wrap value in double quotes. Cannot combine with $filter.
selectNoComma-separated fields to return, e.g. id,subject,from,receivedDateTime
orderbyNoSort expression, e.g. receivedDateTime desc
fetchAllPagesNoFollow @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.
plannerTaskIdYesValue for the 'plannerTaskId' path segment. Pass it under the name 'plannerTaskId', not as 'id'. Use the 'id' field of the planner task object as returned by Microsoft Graph.
includeHeadersNoInclude response headers (including ETag) in the response metadata
excludeResponseNoExclude the full response body and only return success or failure indication
