OneNote Hello World

Overview

Create your first OneNote notebook, section, and page through the Graph API. The critical pitfall this skill addresses: OneNote pages require strict XHTML (not regular HTML). Missing closing tags, unsupported attributes, or table features like rowspan/colspan cause silent content corruption where the API returns 200 OK but the page renders incorrectly or with missing content.

This skill walks through the full creation chain — notebook, section, page — with correct XHTML, then reads back the content to demonstrate that output HTML differs from input HTML.

Prerequisites

Completed onenote-install-auth — you have a working GraphServiceClient (Python) or Client (TypeScript)
Azure AD app with Notes.ReadWrite permission scope
Node.js 18+ or Python 3.10+

Instructions

Step 1: Create a Notebook

// TypeScript — create a new notebook
const notebook = await client.api("/me/onenote/notebooks").post({
  displayName: "Dev Integration Test"
});
console.log(`Notebook created: ${notebook.displayName} (${notebook.id})`);
// Save notebook.id — you need it for creating sections

# Python — create a new notebook
from msgraph.generated.models.notebook import Notebook

request_body = Notebook(display_name="Dev Integration Test")
notebook = await client.me.onenote.notebooks.post(request_body)
print(f"Notebook created: {notebook.display_name} ({notebook.id})")

Naming rules: Notebook names must be unique per user. If a notebook with the same name exists, you get a 400 error with code 20117. Use a timestamp suffix for test notebooks: f"Test-{datetime.now().isoformat()}".

Step 2: Create a Section

// TypeScript — create a section inside the notebook
const section = await client
  .api(`/me/onenote/notebooks/${notebook.id}/sections`)
  .post({ displayName: "Getting Started" });
console.log(`Section created: ${section.displayName} (${section.id})`);

# Python — create a section
from msgraph.generated.models.onenote_section import OnenoteSection

section_body = OnenoteSection(display_name="Getting Started")
section = await client.me.onenote.notebooks.by_notebook_id(
    notebook.id
).sections.post(section_body)
print(f"Section created: {section.display_name} ({section.id})")

Step 3: Create a Page with Correct XHTML

This is where most integrations break. OneNote requires XHTML — every tag must close, the document must be UTF-8, and several HTML features are silently dropped.

VALID XHTML (this works):

<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>Sprint Planning — March 2026</title>
    <meta name="created" content="2026-03-23T10:00:00-05:00" />
  </head>
  <body>
    <h1>Sprint Planning Notes</h1>
    <p>Attendees: Alice, Bob, Charlie</p>

    <h2>Action Items</h2>
    <ul>
      <li data-tag="to-do">Deploy feature X by Friday</li>
      <li data-tag="to-do">Review PR #488</li>
      <li data-tag="to-do:completed">Set up CI pipeline</li>
    </ul>

    <h2>Decisions</h2>
    <p>Approved migration to delegated auth. Deadline: <strong>April 15</strong>.</p>

    <table>
      <tr>
        <td>Task</td>
        <td>Owner</td>
        <td>Status</td>
      </tr>
      <tr>
        <td>Auth migration</td>
        <td>Alice</td>
        <td>In progress</td>
      </tr>
    </table>

    <br />
    <p><em>Next meeting: March 30, 2026</em></p>
  </body>
</html>

INVALID HTML (common mistakes that cause silent failures):

<!-- WRONG: unclosed tags — content after <br> may be lost -->
<p>Line one<br>Line two</p>

<!-- CORRECT: self-closing tags -->
<p>Line one<br />Line two</p>

<!-- WRONG: rowspan/colspan — silently dropped, table layout breaks -->
<td rowspan="2">Merged cell</td>

<!-- CORRECT: use separate rows, no merge attributes -->
<td>Row 1</td>

<!-- WRONG: <img> without self-close -->
<img src="https://example.com/chart.png" alt="Chart">

<!-- CORRECT: self-closing img -->
<img src="https://example.com/chart.png" alt="Chart" />

<!-- WRONG: style attributes with unsupported CSS — silently ignored -->
<p style="display: flex; gap: 8px;">Content</p>

<!-- CORRECT: only supported inline styles -->
<p style="color: #333; font-size: 14pt;">Content</p>

Send the page:

// TypeScript — create page with XHTML content
const xhtml = `<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
  <head><title>Hello from Graph API</title></head>
  <body>
    <h1>Hello World</h1>
    <p>Created via Microsoft Graph API at ${new Date().toISOString()}</p>
    <ul>
      <li data-tag="to-do">First task</li>
      <li data-tag="to-do">Second task</li>
    </ul>
  </body>
</html>`;

const page = await client
  .api(`/me/onenote/sections/${section.id}/pages`)
  .header("Content-Type", "text/html")
  .post(xhtml);

console.log(`Page created: ${page.title} (${page.id})`);

# Python — create page via raw HTTP (SDK page creation uses HTML body)
import httpx

headers = {
    "Authorization": f"Bearer {token}",
    "Content-Type": "text/html",
}
xhtml = """<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
  <head><title>Hello from Graph API</title></head>
  <body>
    <h1>Hello World</h1>
    <p>Created via Microsoft Graph API</p>
    <ul>
      <li data-tag="to-do">First task</li>
    </ul>
  </body>
</html>"""

resp = httpx.post(
    f"https://graph.microsoft.com/v1.0/me/onenote/sections/{section.id}/pages",
    headers=headers,
    content=xhtml,
)
resp.raise_for_status()
page = resp.json()
print(f"Page created: {page['title']} ({page['id']})")

Step 4: Read Back Page Content

The HTML you get back from GET /pages/{id}/content is NOT the same as what you sent. Graph normalizes the HTML, adds data-id attributes, wraps content in div elements, and may reorder attributes.

// TypeScript — read page content back
// Note: small delay needed — page indexing is async
await new Promise((r) => setTimeout(r, 2000));

const content = await client
  .api(`/me/onenote/pages/${page.id}/content`)
  .get();

// content is an HTML string — not the same as what you sent
// Graph adds: data-id attributes, absolute positioning, div wrappers
console.log("Page HTML (first 500 chars):", content.substring(0, 500));

# Python — read page content
import asyncio
await asyncio.sleep(2)  # Page indexing is async

resp = httpx.get(
    f"https://graph.microsoft.com/v1.0/me/onenote/pages/{page['id']}/content",
    headers={"Authorization": f"Bearer {token}"},
)
print("Output HTML (first 500 chars):", resp.text[:500])
# Notice: output HTML has data-id attrs, absolute positions, normalized structure

Valid data-tag Values for Checklists

data-tag value	Renders as
`to-do`	Unchecked checkbox
`to-do:completed`	Checked checkbox
`important`	Star icon
`question`	Question mark icon
`critical`	Red exclamation
`remember-for-later`	Bookmark icon
`definition`	Definition marker
`highlight`	Yellow highlight

Output

After completing these steps you will have:

A new OneNote notebook with a section and page
A page with correctly formatted XHTML content including checklists
Understanding of input vs output HTML differences
Knowledge of XHTML rules that prevent silent content corruption

Error Handling

Error	Code	Root Cause	Solution
Duplicate notebook name	400 (`20117`)	Notebook with same `displayName` exists	Append timestamp or check existence first
Invalid HTML	400	Malformed XHTML — unclosed tags, bad encoding	Validate XHTML before sending; use XML parser
Section not found	404	Notebook ID or section ID is wrong	Re-fetch notebook, verify ID matches
Empty page content	200 (empty body)	Page created but content >4MB	Check payload size before POST
Missing title	400	`<title>` tag missing from `<head>`	Always include `<head><title>...</title></head>`
Content encoding error	400	Non-UTF-8 characters in HTML	Ensure UTF-8 encoding, strip BOM markers

Examples

Minimal valid page (smallest possible):

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
  <head><title>Minimal Page</title></head>
  <body><p>Content here</p></body>
</html>

Page with image from URL:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
  <head><title>Page with Image</title></head>
  <body>
    <h1>Architecture Diagram</h1>
    <img src="https://example.com/diagram.png" alt="System architecture" />
    <p>Figure 1: Current system architecture</p>
  </body>
</html>
