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": "[email protected]"}
- 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
