notion

Create, read, and update Notion pages, data sources (databases), and blocks via the API.

Setup

• API key (ntn_ prefix) stored at ~/.config/notion/api_key
• Load: NOTION_KEY=$(cat ~/.config/notion/api_key)
• Target pages/databases must be shared with the integration

API Basics

NOTION_KEY=$(cat ~/.config/notion/api_key)

# Helper — all examples below use this
notion_api() {
  local method=$1 endpoint=$2 data=$3
  curl -s -X "$method" "https://api.notion.com/v1$endpoint" \
    -H "Authorization: Bearer $NOTION_KEY" \
    -H "Notion-Version: 2025-09-03" \
    -H "Content-Type: application/json" \
    ${data:+-d "$data"}
}

API version 2025-09-03 (latest). Databases are called "data sources" in this version.

Common Operations

# Search
notion_api POST /search '{"query": "page title"}'

# Get page
notion_api GET /pages/{page_id}

# Get page content (blocks)
notion_api GET /blocks/{page_id}/children

# Create page in a data source
notion_api POST /pages '{
  "parent": {"database_id": "xxx"},
  "properties": {
    "Name": {"title": [{"text": {"content": "New Item"}}]},
    "Status": {"select": {"name": "Todo"}}
  }
}'

# Query a data source
notion_api POST /data_sources/{data_source_id}/query '{
  "filter": {"property": "Status", "select": {"equals": "Active"}},
  "sorts": [{"property": "Date", "direction": "descending"}]
}'

# Create a data source
notion_api POST /data_sources '{
  "parent": {"page_id": "xxx"},
  "title": [{"text": {"content": "My Database"}}],
  "properties": {
    "Name": {"title": {}},
    "Status": {"select": {"options": [{"name": "Todo"}, {"name": "Done"}]}},
    "Date": {"date": {}}
  }
}'

# Update page properties
notion_api PATCH /pages/{page_id} \
  '{"properties": {"Status": {"select": {"name": "Done"}}}}'

# Add blocks to page
notion_api PATCH /blocks/{page_id}/children '{
  "children": [
    {"object": "block", "type": "paragraph", "paragraph": {"rich_text": [{"text": {"content": "Hello"}}]}}
  ]
}'

Property Types

• Title: {"title": [{"text": {"content": "..."}}]}
• Rich text: {"rich_text": [{"text": {"content": "..."}}]}
• Select: {"select": {"name": "Option"}}
• Multi-select: {"multi_select": [{"name": "A"}, {"name": "B"}]}
• Date: {"date": {"start": "2024-01-15", "end": "2024-01-16"}}
• Checkbox: {"checkbox": true}
• Number: {"number": 42}
• URL: {"url": "https://..."}
• Email: {"email": "[e-mail]"}
• Relation: {"relation": [{"id": "page_id"}]}

2025-09-03 API Changes

• Databases → Data Sources: Use /data_sources/ endpoints for queries
• Two IDs per database: database_id (for creating pages) and data_source_id (for querying)
• Search results: Databases return as "object": "data_source"
• Page responses: Include both parent.data_source_id and parent.database_id

Environment

• Key location: ~/.config/notion/api_key (also ~/.config/notion/access_token)
• OAuth config: ~/.config/notion/oauth.env
• Discover workspace page IDs via notion_api POST /search '{"query": "page name"}'

Visual Design Rules (미감 가이드)

1. Use mention links for page references

Mention links create backlinks and show page icons automatically.

// ✓ mention
{"type": "mention", "mention": {"type": "page", "page": {"id": "페이지-UUID"}}}

// ✗ plain text
{"type": "text", "text": {"content": "페이지 이름"}}

2. Skip emoji in text when using mentions

Mentions display the page icon automatically — adding emoji causes duplication.

3. Use callout + mention for navigation hubs

{"object": "block", "type": "callout", "callout": {
    "rich_text": [
        {"type": "mention", "mention": {"type": "page", "page": {"id": "대시보드-UUID"}}},
        {"type": "text", "text": {"content": " · "}},
        {"type": "mention", "mention": {"type"    
    
        
     

4. Preserve child_page blocks

Deleting child_page blocks archives subpages permanently. Always filter them out:

for block in children:
    if block["type"] != "child_page":
        delete_block(block["id"])

5. Page structure pattern

callout (intro/slogan) + color_background
divider
heading_2 (section)
callout (mention links) + gray_background  ← navigation
divider
heading_2 (Quick Links)
bulleted_list_item (mention → description)

6. Icons & covers

• Set a meaningful emoji icon on every page
• Add Unsplash cover images on key pages (w=1500)

7. Mention caveats

• Archived pages render mentions as plain text
• Integration needs access to the target page
• Rate limit: ~3 req/s — use time.sleep(0.35)

Notes

• Page/database IDs are UUIDs (dashes optional)
• Database view filters are UI-only (not settable via API)
• Use is_inline: true to embed data sources in pages
