Google Tasks Two-Way Sync

Manage and schedule your tasks from Google Tasks directly inside Obsidian using OAuth 2.0 authentication.

Verified Integration

Google Tasks shares the same secure, verified Google OAuth infrastructure as our Google Calendar integration. You only need to authenticate your Google Account once to gain access to both Google Calendar and Google Tasks.

Quick Start: Connecting and Configuring

1️⃣ Connecting Your Google Account

If you haven't already connected a Google account: 1. Open Full Calendar Settings → Calendar Sources. 2. Under Integrations, ensure your Google Account is connected. 3. If you connected your account in a previous version of the plugin, you may need to Reconnect the account to authorize the new Google Tasks API permission scope (https://www.googleapis.com/auth/tasks).

2️⃣ Adding Google Tasks Calendars

  1. In the Calendars section of the settings, select Google Tasks from the source type dropdown and click +.
  2. Select your connected Google Account in the setup wizard.
  3. The plugin will fetch and display all available task lists from your Google Tasks account.
  4. Select one or more task lists you want to add, then click Add Google Task List to complete the configuration.

Key Features & Workflows

📥 Zero-Impact Backlog Integration

Any undated or incomplete tasks on your Google Tasks list automatically appear in the sidebar Tasks Backlog panel.

  • Access the Backlog: Open the Tasks Backlog sidebar to view all active, unscheduled tasks.
  • Drag-and-Drop Scheduling: To schedule a task, drag it from the backlog list and drop it onto any date in your calendar view. This instantly writes the corresponding due date back to Google Tasks.

📅 Two-Way Synchronization

  • Dated Tasks: Tasks with due dates appear on the calendar as all-day events.
  • Real-Time Sync: Changing a task title, changing its date on the calendar, or deleting it entirely in Obsidian syncs instantly back to Google Tasks.
  • Completion Toggling: Click the checkbox next to any task in your calendar or backlog view to toggle its completion status. This automatically marks it as completed or incomplete on the web!

📝 Linked Notes

Keep detailed project notes or task descriptions locally in Obsidian while keeping them linked to your remote task. - Click a task event in the calendar or backlog, and click Create Event Note. - A local markdown note will be created, indexed, and linked using Event Linked Notes templates. - The linked note indicator will automatically show that a local page is associated with the Google Task. - The global linked-note strategy applies: Name-based reuses the exact task-title file across due-date changes, while Deadline-based uses dated occurrence identity.

Limitations

  • No Multi-Day Tasks: Google Tasks natively only supports single due dates.
  • No Complex Recurrence: The Google Tasks API does not support standard recurring calendar rules (such as RRULEs). All synchronized tasks are mapped and handled as single events.

Troubleshooting & Mobile Support

  • Android and iOS Authentication Workaround: Direct mobile authentication can fail due to mobile sandboxing. For step-by-step instructions on authenticating Google Tasks on mobile using vault synchronization, see Mobile Authentication Workaround.
  • Manual Authorization: See the Central Troubleshooting Guide for help with manual copy-paste login flows.
