Notion API

Manage pages, databases, and content blocks in Notion workspaces.

When to Use

• Create and update Notion pages
• Query and filter database entries
• Search across workspace content
• Append content blocks to pages
• Manage database schemas and properties

Prerequisites

export NOTION_TOKEN=ntn_your-integration-token

Get API Key

1. Go to https://www.notion.so/profile/integrations
2. Click "New integration"
3. Name your integration and select workspace
4. Copy the "Internal Integration Secret" (ntn_... or secret_...)
5. Important: Share pages/databases with the integration via "Add connections" in Notion

Page ID Format

Notion URLs contain page IDs. Extract and normalize them:

URL: https://www.notion.so/My-Page-2b70e96f0134807d8450c8793839c659
Page ID: 2b70e96f0134807d8450c8793839c659 (remove hyphens if present)

# Normalize page ID (remove hyphens)
PAGE_ID=$(echo "2b70e96f-0134-807d-8450-c8793839c659" | tr -d '-')

Important: When using $VAR in a command that pipes to another command, wrap the command containing $VAR in bash -c '...'. Due to a Claude Code bug, environment variables are silently cleared when pipes are used directly.

bash -c 'curl -s "https://api.example.com" -H "Authorization: Bearer $API_KEY"'

Core APIs

Read Page with Content

Replace <your-page-id> with your actual Notion page ID:

# Get page metadata
bash -c 'curl -s -X GET "https://api.notion.com/v1/pages/<your-page-id>" --header "Authorization: Bearer $NOTION_TOKEN" --header "Notion-Version: 2022-06-28" | jq '"'"'{title: .properties.title.title[0].plain_text, url, last_edited_time}'"'"

# Get page content blocks
bash -c 'curl -s -X GET "https://api.notion.com/v1/blocks/<your-page-id>/children?page_size=100" --header "Authorization: Bearer $NOTION_TOKEN" --header "Notion-Version: 2022-06-28" | jq '"'"'.results[] | {type, text: (.[.type].rich_text // [] | map(.plain_text) | join("")), has_children}'"'"

Read Nested Blocks (Toggle, etc.)

Blocks with has_children: true contain nested content. Replace <your-block-id> with your actual block ID:

bash -c 'curl -s -X GET "https://api.notion.com/v1/blocks/<your-block-id>/children" --header "Authorization: Bearer $NOTION_TOKEN" --header "Notion-Version: 2022-06-28" | jq '"'"'.results[] | {type, text: (.[.type].rich_text // [] | map(.plain_text) | join(""))}'"'"

Search Workspace

Write to /tmp/notion_request.json:

{
  "query": "Meeting Notes",
  "page_size": 10
}

Then run:

bash -c 'curl -s -X POST "https://api.notion.com/v1/search" --header "Authorization: Bearer $NOTION_TOKEN" --header "Notion-Version: 2022-06-28" --header "Content-Type: application/json" -d @/tmp/notion_request.json | jq '"'"'.results[] | {id, object, title: .properties.title.title[0].plain_text // .title[0].plain_text}'"'"

{
  "page_size": 100

All list endpoints support cursor-based pagination:

Write to /tmp/notion_request.json:

{
  "page_size": 100
}

# First request
bash -c 'curl -s -X POST "https://api.notion.com/v1/databases/<your-database-id>/query" --header "Authorization: Bearer $NOTION_TOKEN" --header "Notion-Version: 2022-06-28" --header "Content-Type: application/json" -d @/tmp/notion_request.json'
# Response includes: {"next_cursor": "abc123", "has_more": true}

Write to /tmp/notion_request.json:

{
  "page_size": 100,
  "start_cursor": "<your-cursor>"
}

# Next page
bash -c 'curl -s -X POST "https://api.notion.com/v1/databases/<your-database-id>/query" --header "Authorization: Bearer $NOTION_TOKEN" --header "Notion-Version: 2022-06-28" --header "Content-Type: application/json" -d @/tmp/notion_request.json'
