Notion

Talk to Notion two ways. Same integration token works for both — pick by what's available.

◆ ntn CLI — Notion's official CLI. Shorter syntax, one-line file uploads, required for Workers. macOS + Linux only as of May 2026 (Windows support "coming soon"). Default when installed. ◆ HTTP + curl — works everywhere including Windows. Default fallback when ntn isn't installed.

Setup

1. Get an integration token (required for both paths)

1. Create an integration at https://notion.so/my-integrations
2. Copy the API key (starts with ntn_ or secret_)
3. Store in ${HERMES_HOME:-~/.hermes}/.env:

   NOTION_API_KEY=ntn_your_key_here
   

4. Share target pages/databases with the integration in Notion: page menu ... → Connect to → your integration name. Without this, the API returns 404 for that page even though it exists.

2. Install ntn (preferred path on macOS / Linux)

# Recommended
curl -fsSL https://ntn.dev | bash

# Or via npm (needs Node 22+, npm 10+)
npm install --global ntn

ntn --version    # verify

Skip ntn login — use the integration token instead. This works headlessly, no browser needed:

export NOTION_API_TOKEN=$NOTION_API_KEY      # ntn reads NOTION_API_TOKEN
export NOTION_KEYRING=0                       # don't try to use the OS keychain

Add those exports to your shell profile (or to ${HERMES_HOME:-~/.hermes}/.env) so every session inherits them.

3. Choose path at runtime

if command -v ntn >/dev/null 2>&1; then
  # use ntn
else
  # fall back to curl
fi

Windows users: skip step 2 entirely until native ntn ships — Path B works fine. If you want CLI ergonomics now, install ntn inside WSL2.

API Basics

Notion-Version: 2025-09-03 is required on all HTTP requests. ntn handles this for you. In this version, what users call "databases" are called data sources in the API.

Path A — ntn CLI (preferred, macOS / Linux)

Raw API calls (shorthand for curl)

ntn api v1/users                                  # GET
ntn api v1/pages parent[page_id]=abc123 \         # POST with inline body
  properties[title][0][text][content]="Notes"
ntn api v1/pages/abc123 -X PATCH archived:=true   # PATCH; := is non-string (bool/num/null)
