3. Enable the plugin in the Obsidian settings.

Configuration

3. Under Installed plugins, click the gear icon next to the Ultimate Todoist Sync plugin
4. Enter your Todoist API token

Settings

1. Automatic synchronization interval time The time interval for automatic synchronization is set to 300 seconds by default, which means it runs every 5 minutes. You can modify it yourself.

2. Default project New tasks will be added to the default project, and you can change the default project in the settings or use a project tag to specify a particular project.

3. Sync direction controls

   • Obsidian → Todoist (default: on)
   • Todoist → Obsidian (default: off)

   Each direction can be independently enabled or disabled.

4. Full vault sync By enabling this option, the plugin will automatically add #todoist to all tasks in your vault.

5. Excluded folders Select folders to exclude from Full Vault Sync. Template folders, hidden folders, and plugin storage are excluded automatically.

Usage

Task format

Syntax	Description	Example
#todoist	Tasks marked with #todoist will be added to Todoist, while tasks without the #todoist tag will not be processed. If you have enabled Full vault sync in the settings, #todoist will be added automatically.	- [ ] task #todoist
📅YYYY-MM-DD	The date format is 📅YYYY-MM-DD, indicating the due date of a task.	- [ ] task content 📅2025-02-05 #todoist Supports the following calendar emojis: 📅📆🗓🗓️
#projectTag	New tasks will be added to the default project (e.g. inbox). You can change the default project in the settings or use a tag with the same name to specify a particular project.	- [ ] taskA #todoist will be added to inbox. - [ ] taskB #tag #testProject #todoist will be added to testProject.
#tag	Note that all tags without a project of the same name are treated as normal tags.	- [ ] task #tagA #tagB #tagC #todoist
!!<number>	The priority of the task (a number between 1 and 4, 4 for very urgent and 1 for natural). Note: Keep in mind that very urgent is the priority 1 on clients. So, the priority 1 in the client corresponds to the number 4 here (because that's how the official API of Todoist is designed).	- [ ] task !!4 #todoist

Set a default project for each file separately

The default project in the setting applies to all files. You can set a separate default project for each file using command.

You can see the current file's default project in the status bar at the bottom right corner.

Development

Prerequisites

• Node.js (v16+)
• npm
• An Obsidian vault for testing

Quick Start

The recommended way is to clone the repo directly into your vault's plugin directory, so that builds are immediately available to Obsidian:

cd /path/to/your-vault/.obsidian/plugins/
git clone https://github.com/HeroBlackInk/ultimate-todoist-sync-for-obsidian.git
cd ultimate-todoist-sync-for-obsidian
npm install

Build

# Development (watch mode, auto-rebuilds on file change)
npm run dev

# Production (type-check + bundle)
npm run build

After each rebuild, reload Obsidian (Ctrl/Cmd+P → "Reload app without saving") or disable and re-enable the plugin in settings.
