Notion Sync for Obsidian

Synchronize your entire Obsidian vault to Notion — preserving folder hierarchy, markdown formatting, internal links, frontmatter metadata, and attachments.

---

Features

• Full vault sync — mirrors your complete vault structure to Notion in a single command
• Incremental sync — only pushes files that have changed since the last sync
• On-save sync — automatically syncs a note to Notion the moment you save it
• Scheduled sync — runs sync automatically on a configurable interval
• Folder hierarchy — recreates your folder tree as nested Notion pages
• Markdown conversion — headings, bold, italic, code, tables, blockquotes, lists, dividers, and more all convert to native Notion blocks
• Frontmatter metadata — YAML frontmatter is parsed and synced as Notion page properties
• Internal link resolution — [[wikilinks]] are resolved to their synced Notion page URLs
• Attachment support — images and file embeds (![[file.png]]) can be uploaded to Notion via a configurable upload endpoint
• Sync log — an in-app log modal shows every sync operation with timestamps and status
• Connection test — verify your Notion API token with a single click before syncing
• Abort support — cancel an in-progress sync at any time

---

Requirements

• Obsidian 1.4.0 or later
• A Notion integration with access to your target page
• Desktop only (not supported on mobile)

---

Setup

1. Create a Notion Integration

1. Go to notion.so/my-integrations
2. Click New integration, give it a name, and select your workspace
3. Copy the Internal Integration Secret — this is your API token

2. Share Your Root Notion Page

1. Open the Notion page you want to use as the vault root
2. Click Share → Invite → search for your integration and add it
3. Copy the page ID from the URL:
   https://notion.so/Your-Page-Title-abc123def456...

3. Configure the Plugin

Open Settings → Notion Sync and fill in:

Setting	Description
Notion API Token	Your integration secret (secret_...)
Root Notion Page ID	The page ID from step 2
Sync Mode	Manual / On Save / Scheduled / Current File
Sync Attachments	Upload images and file embeds
Sync Metadata	Push YAML frontmatter as page properties
Sync Interval	How often to auto-sync (minutes, scheduled mode only)
Attachment Upload URL	Optional external endpoint for file uploads

Click Test Connection to verify everything is working.

---

Sync Modes

Mode	Behavior
Manual	Only syncs when you run a command
On Save	Syncs the current file every time you save
Scheduled	Syncs the entire vault at a set interval
Current File	Syncs only the currently open file on demand

---

Commands

All commands are available via the Command Palette (Cmd/Ctrl + P):

Command	Description
Sync entire vault to Notion	Full sync of all notes and folders
Sync current note to Notion	Push only the currently open note
Sync changed files to Notion	Incremental sync — only changed files
Rebuild Notion hierarchy	Re-create the folder structure in Notion without re-syncing content
Open sync log	View a detailed log of all sync operations

---

Markdown Support

The following Obsidian/Markdown elements are converted to native Notion blocks:

• Headings (#, ##, ###)
• Paragraphs
• Bold, italic, strikethrough, inline code
• Bulleted and numbered lists
• To-do checkboxes (- [ ] / - [x])
• Block quotes (>)
• Code blocks (fenced with language hint)
• Tables
• Horizontal dividers (---)
• Embedded images and files (![[...]])
• Internal wikilinks ([[Note Name]]) resolved to Notion URLs

---

Attachment Uploads

By default, attachment embeds are converted to placeholder callout blocks in Notion. To enable real image uploads:

1. Set up an external file hosting endpoint (e.g., Cloudflare R2, S3, or your own server)
2. Enter the endpoint URL in Settings → Attachment Upload URL

The plugin will POST the file binary to this URL and use the returned url field as the Notion image source.

---

Privacy & Security

Your Notion API token and page IDs are stored locally in data.json inside your vault and are never sent anywhere except directly to the official Notion API (api.notion.com). This file is excluded from version control by the plugin's .gitignore.

---
