notion
Use the Notion API to create/read/update pages, data sources (databases), and blocks.
Setup
-
Create an integration at https://notion.so/my-integrations
-
Copy the API key (starts with ntn_ or secret_ )
-
Store it:
mkdir -p ~/.config/notion echo "ntn_your_key_here" > ~/.config/notion/api_key
- Share target pages/databases with your integration (click "..." → "Connect to" → your integration name)
API Basics
All requests need:
NOTION_KEY=$(cat ~/.config/notion/api_key)
curl -X GET "https://api.notion.com/v1/..."
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
Note: The Notion-Version header is required. This skill uses 2025-09-03 (latest). In this version, databases are called "data sources" in the API.
Common Operations
Search for pages and data sources:
curl -X POST "https://api.notion.com/v1/search"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
-d '{"query": "page title"}'
Get page:
curl "https://api.notion.com/v1/pages/{page_id}"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
Get page content (blocks):
curl "https://api.notion.com/v1/blocks/{page_id}/children"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
Create page in a data source:
curl -X POST "https://api.notion.com/v1/pages"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
-d '{
"parent": {"database_id": "xxx"},
"properties": {
"Name": {"title": [{"text": {"content": "New Item"}}]},
"Status": {"select": {"name": "Todo"}}
}
}'
Query a data source (database):
curl -X POST "https://api.notion.com/v1/data_sources/{data_source_id}/query"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
-d '{
"filter": {"property": "Status", "select": {"equals": "Active"}},
"sorts": [{"property": "Date", "direction": "descending"}]
}'
Create a data source (database):
curl -X POST "https://api.notion.com/v1/data_sources"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
-d '{
"parent": {"page_id": "xxx"},
"title": [{"text": {"content": "My Database"}}],
"properties": {
"Name": {"title": {}},
"Status": {"select": {"options": [{"name": "Todo"}, {"name": "Done"}]}},
"Date": {"date": {}}
}
}'
Update page properties:
curl -X PATCH "https://api.notion.com/v1/pages/{page_id}"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
-d '{"properties": {"Status": {"select": {"name": "Done"}}}}'
Add blocks to page:
curl -X PATCH "https://api.notion.com/v1/blocks/{page_id}/children"
-H "Authorization: Bearer $NOTION_KEY"
-H "Notion-Version: 2025-09-03"
-H "Content-Type: application/json"
-d '{
"children": [
{"object": "block", "type": "paragraph", "paragraph": {"rich_text": [{"text": {"content": "Hello"}}]}}
]
}'
Property Types
Common property formats for database items:
-
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": "a@b.com"}
-
Relation: {"relation": [{"id": "page_id"}]}
Key Differences in 2025-09-03
-
Databases → Data Sources: Use /data_sources/ endpoints for queries and retrieval
-
Two IDs: Each database now has both a database_id and a data_source_id
-
Use database_id when creating pages (parent: {"database_id": "..."} )
-
Use data_source_id when querying (POST /v1/data_sources/{id}/query )
-
Search results: Databases return as "object": "data_source" with their data_source_id
-
Parent in responses: Pages show parent.data_source_id alongside parent.database_id
-
Finding the data_source_id: Search for the database, or call GET /v1/data_sources/{data_source_id}
Notes
-
Page/database IDs are UUIDs (with or without dashes)
-
The API cannot set database view filters — that's UI-only
-
Rate limit: ~3 requests/second average
-
Use is_inline: true when creating data sources to embed them in pages
