- Work item conversation
Send a text message into a Siftable work item and receive the conversation back. Open a conversation by setting message.metadata.siftWorkItemId to the work item UUID; continue it by reusing the returned contextId and taskId. A credential bound to an agent alias, or a workspace service token, already determines the workspace; an unbound personal credential must set message.metadata.siftWorkspaceId to the workspace UUID for organization-scoped work items and may omit it for personal ones. Data parts may carry Sift artifact_reference or work_item_reference records. Raw and URL parts are not accepted.
