Monitor Notion and Todoist in real time with Redis-backed loop prevention to keep tasks and calendars in sync across workspaces.
The AI agent synchronizes Notion and Todoist tasks in real time via Redis-backed loop prevention. It uses Notion as the source of truth for task fields and maps Name, Priority, Due, Status, and Todoist ID to the corresponding Todoist fields. It also performs a daily full sync to resolve drift and keep calendar events aligned across Notion, Todoist, and connected calendars.
Handles end-to-end two-way synchronization with explicit mappings.
Syncs changes from Notion to Todoist in near real time.
Syncs changes from Todoist to Notion in near real time.
Locks triggers for 15 seconds to prevent update loops.
Stores Todoist IDs in Notion to maintain linkage between tasks.
Applies Obsolete status to avoid accidental deletions.
Performs a daily full sync to fix inconsistencies.
Before: Notion and Todoist drift requires manual reconciliation. After: Tasks stay synchronized across both apps with automatic drift correction.
A simple 3-step system for reliable cross-app syncing.
A registered webhook from either Notion or Todoist wakes the AI agent and the current task data is fetched from both sides to detect changes.
Redis locks updates for 15 seconds to prevent loops, compares the changes, and updates the opposing system accordingly.
A nightly full sync fixes drift and ensures ongoing accuracy of mappings and calendar alignment.
A realistic scenario showing the AI agent in action.
Scenario: A Notion task named 'Launch Campaign' has its Priority raised from 3 to 1 and its Due date moved from May 14 to May 12. The AI agent, triggered by the Notion webhook, updates the linked Todoist task’s priority and due date. It stores the Todoist ID in the Notion task to maintain linkage, and adjusts the Status if needed (e.g., Backlog to In Progress). A daily full sync runs at night to correct any residual drift and ensure both sides reflect the same state.
Roles that gain concrete workflow improvements.
Need a single source of truth for backlog across Notion and Todoist.
Coordinate tasks across multiple teams with synchronized statuses and deadlines.
Keep sprint tasks synchronized between planning (Notion) and execution (Todoist).
Reduce drift between systems that track daily workflows and calendars.
Simplify setup and maintenance with a centralized sync agent.
Manage tasks across Notion and Todoist when working across clients.
Tools involved and what the AI agent does inside each.
Serves as the source of truth for task data and mapping fields; updates propagate to Todoist.
Receives updates from Notion; Todoist task IDs are stored in Notion for linkage.
Provides a 15-second update lock to prevent update loops and coordinate trigger handling.
Practical scenarios where the AI agent adds value.
Common questions and detailed answers.
The AI agent uses a task-level, time-bound lock in Redis to prevent cycles. When an update is detected on one side, a 15-second window is created during which further webhook-triggered updates are ignored for that task. This prevents rapid back-and-forth updates from looping. If a change arrives within the lock, it is treated as a follow-up and reconciled accordingly. This ensures stability while keeping updates timely.
Subtasks are not automatically linked to their parent in this integration yet. The mapping focuses on core task fields (Name, Priority, Due, Status) and the Todoist ID linkage within Notion. Subtask handling could be introduced later with an expanded mapping schema. For now, users should manage subtasks at the Todoist level or incorporate them into the Notion description as a workaround. This design keeps the agent reliable and predictable.
Recurring tasks are not currently supported in the two-way sync workflow. Each occurrence would require a separate explicit task to be updated in both systems. The agent focuses on one-off tasks with clear Due dates and statuses. If recurring task support is added, it will include specialized mapping for recurrence rules and IDs. Until then, plan recurring work as discrete tasks.
You start with tokens and credentials for Notion and Todoist, then enable webhooks for the appropriate databases/projects. The AI agent setup guides you through cloning or importing the configuration and mapping credentials. You may need to adjust access permissions and confirm the mappings for fields like Name, Priority, Due, and Status. The included instructions also point to the daily full-sync configuration. After setup, webhooks trigger real-time syncing as changes occur.
Conflicts are resolved by the Redis-based lock and the source-of-truth ordering. If Notion is the source of truth for a given task, Todoist updates are applied to align with Notion. If a conflict occurs during the 15-second window, changes are reconciled by comparing the latest data from both sides and applying the most recent legitimate update. The daily full sync also rechecks mappings to ensure consistency and resolve any accumulated drift.
Security depends on how credentials are stored and transmitted. Use encrypted tokens and restrict webhook endpoints to trusted environments. The AI agent stores only task mappings and IDs necessary for synchronization, not full copies of data. Access should be limited to authorized users in your workspace. Regularly rotate tokens and monitor for unusual webhook activity.
The daily full sync is scheduled to run once per day, typically during off-peak hours, to minimize disruption. It re-evaluates all mapped tasks to fix any drift between Notion and Todoist. If discrepancies are detected, updates are applied to restore alignment and ensure data integrity. The exact time can be configured during setup to fit your workflow.
