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, with 429 rate_limited responses using Retry-After Append block children: up to 100 children per request, up to two levels of nesting in a single append request Payload size limits: up to 1000 block elements and 500KB overall Use is_inline: true when creating data sources to embed them in pages
