Common Commands

Using Python notion-client (Primary)

python

from notion_client import Client

client = Client(auth=os.environ["NOTION_API_KEY"])

# Search pages/databases
result = client.search(query="keyword")

# Get page content
page = client.pages.retrieve(page_id="page-id")
blocks = client.blocks.children.list(block_id="page-id")

# Create pages
new_page = client.pages.create(
    parent={"database_id": "database-id"},
    properties={"title": {"title": [{"text": "Page Title"}]}}
)

# Append blocks (add content)
client.blocks.children.append(
    block_id="page-id",
    children=[{"object": "block", "type": "paragraph", "paragraph": {"rich_text": [{"text": {"content": "Text"}}]}}]
)

# Update pages
client.pages.update(
    page_id="page-id",
    properties={"Status": {"select": {"name": "Done"}}}
)

# Query databases
database = client.databases.query(database_id="database-id")

Quick Bash One-liners

bash

# Search
python3 -c 'from notion_client import Client; c=Client(); print(c.search(query="keyword"))'

# Get page
python3 -c 'from notion_client import Client; c=Client(); print(c.pages.retrieve("page-id"))'

Quick Examples

python

from notion_client import Client
import os

client = Client(auth=os.environ["NOTION_API_KEY"])

# Find pages
results = client.search(query="Project Alpha")

# Create a new page in a database
new_page = client.pages.create(
    parent={"database_id": "database-id"},
    properties={
        "Name": {"title": [{"text": "Review PR #123"}]},
        "Status": {"select": {"name": "Todo"}},
        "Priority": {"select": {"name": "High"}}
    }
)

# Append content to a page (with batch processing)
blocks = [
    {
        "type": "heading_2",
        "heading_2": {"rich_text": [{"type": "text", "text": {"content": "Notes"}}]}
    },
    {
        "type": "bulleted_list_item",
        "bulleted_list_item": {"rich_text": [{"type": "text", "text": {"content": "Item 1"}}]}
    },
    {
        "type": "bulleted_list_item",
        "bulleted_list_item": {"rich_text": [{"type": "text", "text": {"content": "Item 2"}}]}
    }
]

# Process in batches of 100 (Notion API limit)
for i in range(0, len(blocks), 100):
    batch = blocks[i:i+100]
    client.blocks.children.append(
        block_id="page-id",
        children=batch
    )

# Query database with filter
database = client.databases.query(
    database_id="database-id",
    filter={
        "property": "Date",
        "date": {"equals": "2025-02-05"}
    }
)

Bash One-liner Examples

bash

# Search
python3 -c 'from notion_client import Client; c=Client(); print(c.search(query="Project"))'

# Add page
python3 -c 'from notion_client import Client; c=Client(); c.pages.create(parent={"database_id": "db-id"}, properties={"title": {"title": [{"text": "New Page"}]}})'

Database Query Filters

Filter Type	Example
Text	`property=Name=value=MyTask`
Select	`property=Status=value=Todo`
Date	`property=Date=value=today`
Checkbox	`property=Done=value=true`
Multi-select	`property=Tags=value=Urgent`

Setup Integration

•Go to https://www.notion.so/my-integrations
•Create new integration → Copy token
•Share pages/databases with the integration
•Set NOTION_API_KEY environment variable
•Run notion-shell list to test

⚠️ Important API Constraints (Learned from Practice)

Block Type Naming (Critical)

Notion API is strict about block type names. Use exact type names:

Incorrect	Correct
`bullet_list_item`	`bulleted_list_item`
`number_list_item`	`numbered_list_item`

Rich Text Structure

python

# ❌ WRONG - annotations as direct property
{
    "type": "text",
    "text": {"content": "Bold text"},
    "annotations": {"bold": True}  # This causes API error
}

# ✅ CORRECT - annotations inside text object
{
    "type": "text",
    "text": {
        "content": "Bold text",
        "annotations": {"bold": True}  # Annotations here
    }
}

Batch Processing Limit

•Notion API allows max 100 blocks per request
•Always split large content into batches:

python

for i in range(0, len(blocks), 100):
    batch = blocks[i:i+100]
    client.blocks.children.append(block_id=page_id, children=batch)

Recommended Workflow

•Plan content in Markdown - Easier to write and review
•Convert to Notion API format - Use correct block types
•Batch into chunks of 100 - Prevent API errors
•Handle errors gracefully - Notion error messages are specific and helpful
•Style in Notion UI - Let Notion handle formatting instead of complex API calls

Common Block Types Reference

python

# Headings
{"type": "heading_1", "heading_1": {"rich_text": [{"type": "text", "text": {"content": "Title"}}]}}
{"type": "heading_2", "heading_2": {"rich_text": [{"type": "text", "text": {"content": "Subtitle"}}]}}
{"type": "heading_3", "heading_3": {"rich_text": [{"type": "text", "text": {"content": "Section"}}]}}

# Lists
{"type": "bulleted_list_item", "bulleted_list_item": {"rich_text": [{"type": "text", "text": {"content": "Item"}}]}}
{"type": "numbered_list_item", "numbered_list_item": {"rich_text": [{"type": "text", "text": {"content": "Item"}}]}}

# Basic
{"type": "paragraph", "paragraph": {"rich_text": [{"type": "text", "text": {"content": "Text"}}]}}
{"type": "divider", "divider": {}}

# Toggle
{"type": "toggle", "toggle": {"rich_text": [{"type": "text", "text": {"content": "Click to expand"}}]}}

Error Handling

Notion API errors are very specific - read them carefully:

code

body.children[10].type should be "bulleted_list_item" instead of "bullet_list_item"

This tells you exactly:

•Which block has the error (index 10)
•What the correct value should be
•Fix and retry
