How Two-Way Sync Handles Completed and Deleted Tasks

Understand completion, deletion, archival, conflict, and recovery decisions before connecting two task systems.

Completion is safer than deletion

Completion is a reversible state represented by a field. Deletion removes a record and may not be reversible through the API. For that reason, many workflows should prefer completing or archiving tasks over deleting them.

Questions every sync should answer

  • Does completing a task update both systems?
  • Does reopening a task flow back?
  • What happens when a linked task is deleted?
  • Can one system archive instead of delete?
  • How are simultaneous edits resolved?
  • Is there an activity log for failed operations?

A cautious deletion policy

  1. Complete tasks during normal work.
  2. Archive or filter completed Notion records during reviews.
  3. Delete only when the item was created accidentally or contains information that must be removed.
  4. After deleting a linked task, review the next sync activity before making more changes.

Conflicts and partial failures

A sync can encounter changes in both systems or a successful target write followed by a failed link-back operation. Reliable systems use timestamps, stable identifiers, retries, and explicit failure records to reduce data loss and duplication.
