Notion

Notion

Interact with Notion via the REST API using curl. No separate CLI install needed.

Prerequisites

No install needed beyond curl (pre-installed on macOS/Linux).

Set up credentials:

export NOTION_API_KEY="secret_xxxxxxxxxxxx"

Get your key:

1. Go to https://www.notion.so/my-integrations
2. Create a new integration → copy the "Internal Integration Token"
3. Share target pages/databases with the integration (open in Notion → Share → invite integration)

Store in shell profile or in 1Password and inject via op run.

Create a new note under a parent page: Set PARENT_ID to your workspace page ID, then:

curl -s -X POST "https://api.notion.com/v1/pages" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2022-06-28" \
  -H "Content-Type: application/json" \
  -d '{"parent": {"page_id": "'$PARENT_ID'"}, "properties": {"title": {"title": [{"text": {"content": "My New Note"}}]}}}'

Rules

• Always check that NOTION_API_KEY is set: [ -z "$NOTION_API_KEY" ] && echo "Not set"
• If not set, guide the user to https://www.notion.so/my-integrations and stop
• NEVER log or store the API key in memory or workspace files
• Always pipe curl output through jq; install with brew install jq if needed
• Page IDs are 32-char hex strings (with or without dashes) — extract from Notion URLs
• Remind the user to share the page/database with the integration if getting 404 errors
• When reading page content, save long content to workspace/notion-<page-id>.md rather than displaying raw
• Keep responses concise: confirm action in 1-2 lines and show the page title/URL
