Webhook and Todoist integration

Purpose This solution enables you to manage all your Notion and Todoist tasks from different workspaces as well as your calendar events in a single place. All tasks can be managed in Todoist and additionally Fantastical can be used to manage scheduled tasks & events all together. Demo & Explanation How it works The realtime sync consists of two workflows, both triggered by a registered webhook from either Notion or Todoist To avoid overwrites by lately arriving webhook calls, every time the current task is retrieved from both sides. Redis is used to prevent from endless loops, since an update in one system triggers another webhook call again. Using the ID of the task, the trigger is being locked down for 15 seconds. Depending on the detected changes, the other side is updated accordingly. Generally Notion is treaded as the main source. Using an "Obsolete" Status, it is guaranteed, that tasks never get deleted entirely by accident. The Todoist ID is stored in the Notion task, so they stay linked together An additional full sync workflow daily fixes inconsistencies, if any of them occurred, since webhooks cannot be trusted entirely. Since Todoist requires a more complex setup, a tiny workflow helps with activating the webhook. Another tiny workflow helps generating a global config, which is used by all workflows for mapping purposes. Mapping (Notion >> Todoist) Name: Task Name Priority: Priority (1: do first, 2: urgent, 3: important, 4: unset) Due: Date Status: Section (Done: completed, Obsolete: deleted) <page_link>: Description (read-only) Todoist ID: <task_id> Current limitations Changes on the same task cannot be made simultaneously in both systems within a 15-20 second time frame Subtasks are not linked automatically to their parent yet Recurring tasks are not supported yet Tasks names do not support URL’s yet Compatibility n8n v2.5.0 and above Updates This templated has been updated to work with the new "combined" Todoist API (v1). The general flow works exactly the same as before. Only the setup of the Todoist Webhook might look a tiny bit different then shown in the setup video, so please also have a look at the yellow sticky notes. Prerequisites Notion A database must already exist (get a basic template here) with the following properties (case matters!): Text: "Name" Status: "Status", containing at least the options "Backlog", "In progress", "Done", "Obsolete" Select: "Priority", containing the options "do first", "urgent", "important" Date: "Due" Checkbox: "Focus" Text: "Todoist ID" Todoist A project must already exist with the same sections like defined as Status in Notion (except Done and Obsolete) Redis Create a Free Redis Cloud instance or self-host Setup The setup involves quite a lot of steps, yet many of them can be automated for business internal purposes. Just follow the video or do the following steps: Setup credentials for Notion (access token), Todoist (access token) and Redis - you can also create empty credentials and populate these later during further setup Clone this workflow by clicking the "Use workflow" button and then choosing your n8n instance - otherwise you need to map the credentials of many nodes. Follow the instructions described within the bundle of sticky notes on the top left of the workflow How to use You can apply changes (create, update, delete) to tasks both in Notion and Todoist which then get synced over within a couple of seconds (this is handled by the differential realtime sync) The daily running full sync, resolves possible discrepancies in Todoist and sends a summary via email, if anything needed to be updated. In case that contains an unintended change, you can jump to the Task from the email directly to fix it manually.

Public Transport Delay Tracker with Microsoft Teams and Todoist ⚠️ COMMUNITY TEMPLATE DISCLAIMER: This is a community-contributed template that uses ScrapeGraphAI (a community node). Please ensure you have the ScrapeGraphAI community node installed in your n8n instance before using this template. This workflow continuously monitors public-transportation websites and apps for real-time schedule changes and delays, then posts an alert to a Microsoft Teams channel and creates a follow-up task in Todoist. It is ideal for commuters or travel coordinators who need instant, actionable updates about transit disruptions. Pre-conditions/Requirements Prerequisites An n8n instance (self-hosted or n8n cloud) ScrapeGraphAI community node installed Microsoft Teams account with permission to create an Incoming Webhook Todoist account with at least one project Access to target transit authority websites or APIs Required Credentials ScrapeGraphAI API Key** – Enables scraping of transit data Microsoft Teams Webhook URL** – Sends messages to a specific channel Todoist API Token** – Creates follow-up tasks (Optional) Transit API key if you are using a protected data source Specific Setup Requirements | Resource | What you need | |--------------------------|---------------------------------------------------------------| | Teams Channel | Create a channel → Add “Incoming Webhook” → copy the URL | | Todoist Project | Create “Transit Alerts” project and note its Project ID | | Transit URLs/APIs | Confirm the URLs/pages contain the schedule & delay elements | How it works This workflow continuously monitors public-transportation websites and apps for real-time schedule changes and delays, then posts an alert to a Microsoft Teams channel and creates a follow-up task in Todoist. It is ideal for commuters or travel coordinators who need instant, actionable updates about transit disruptions. Key Steps: Webhook (Trigger)**: Starts the workflow on a schedule or via HTTP call. Set Node**: Defines target transit URLs and parsing rules. ScrapeGraphAI Node**: Scrapes live schedule and delay data. Code Node**: Normalizes scraped data, converts times, and flags delays. IF Node**: Determines if a delay exceeds the user-defined threshold. Microsoft Teams Node**: Sends formatted alert message to the selected Teams channel. Todoist Node**: Creates a “Check alternate route” task with due date equal to the delayed departure time. Sticky Note Node**: Holds a blueprint-level explanation for future editors. Set up steps Setup Time: 15–20 minutes Install community node: In n8n, go to “Manage Nodes” → “Install” → search for “ScrapeGraphAI” → install and restart n8n. Create Teams webhook: In Microsoft Teams, open target channel → “Connectors” → “Incoming Webhook” → give it a name/icon → copy the URL. Create Todoist API token: Todoist → Settings → Integrations → copy your personal API token. Add credentials in n8n: Settings → Credentials → create new for ScrapeGraphAI, Microsoft Teams, and Todoist. Import workflow template: File → Import Workflow JSON → select this template. Configure Set node: Replace example transit URLs with those of your local transit authority. Adjust delay threshold: In the Code node, edit const MAX_DELAY_MINUTES = 5; as needed. Activate workflow: Toggle “Active”. Monitor executions to ensure messages and tasks are created. Node Descriptions Core Workflow Nodes: Webhook** – Triggers workflow on schedule or external HTTP request. Set** – Supplies list of URLs and scraping selectors. ScrapeGraphAI** – Scrapes timetable, status, and delay indicators. Code** – Parses results, converts to minutes, and builds payloads. IF** – Compares delay duration to threshold. Microsoft Teams** – Posts formatted adaptive-card-style message. Todoist** – Adds a task with priority and due date. Sticky Note** – Internal documentation inside the workflow canvas. Data Flow: Webhook → Set → ScrapeGraphAI → Code → IF a. IF (true branch) → Microsoft Teams → Todoist b. IF (false branch) → (workflow ends) Customization Examples Change alert message formatting // In the Code node const message = `⚠️ Delay Alert: Route: ${item.route} Expected: ${item.scheduled} New Time: ${item.newTime} Delay: ${item.delay} min Link: ${item.url}`; return [{ json: { message } }]; Post to multiple Teams channels // Duplicate the Microsoft Teams node and reference a different credential items.forEach(item => { item.json.webhookUrl = $node["Set"].json["secondaryChannelWebhook"]; }); return items; Data Output Format The workflow outputs structured JSON data: { "route": "Blue Line", "scheduled": "2024-12-01T14:25:00Z", "newTime": "2024-12-01T14:45:00Z", "delay": 20, "status": "Delayed", "url": "https://transit.example.com/blue-line/status" } Troubleshooting Common Issues Scraping returns empty data – Verify CSS selectors/XPath in the Set node and ensure the target site hasn’t changed its markup. Teams message not sent – Check that the stored webhook URL is correct and the connector is still active. Todoist task duplicated – Add a unique key (e.g., route + timestamp) to avoid inserting duplicates. Performance Tips Limit the number of URLs per execution when monitoring many routes. Cache previous scrape results to avoid hitting site rate limits. Pro Tips: Use n8n’s built-in Cron instead of Webhook if you only need periodic polling. Add a SplitInBatches node after scraping to process large route lists incrementally. Enable execution logging to an external database for detailed audit trails.
