OneNote — Full CRUD Lifecycle (Notebooks, Sections, Pages)

Overview

OneNote's hierarchy — Notebook, Section Group, Section, Page — maps cleanly to Graph API endpoints, but the implementation has sharp edges. Section groups created via API sometimes don't render in the desktop client. Page content must be strict XHTML with self-closing tags, and the HTML you send in differs from the HTML you get back. This skill covers the full create/read/update/delete lifecycle with production-safe patterns for every level of the hierarchy.

Key pain points addressed:

Page content requires XHTML (all tags must close, UTF-8 encoded, no rowspan/colspan)
Section groups support API nesting depths that the desktop app cannot render beyond two levels
Output HTML from GET /pages/{id}/content contains Graph-injected data-id attributes and rewritten image URLs that differ from your input HTML
PATCH page updates use a JSON array with target/action/content — not raw HTML

Prerequisites

Azure app registration with delegated permissions: Notes.ReadWrite or Notes.ReadWrite.All
App-only auth deprecated March 31, 2025 — use delegated auth only (DeviceCodeCredential or InteractiveBrowserCredential)
Python: pip install msgraph-sdk azure-identity
Node/TypeScript: npm install @microsoft/microsoft-graph-client @azure/identity @azure/msal-node

Instructions

Step 1 — Authenticate with Delegated Credentials

TypeScript:

import { Client } from "@microsoft/microsoft-graph-client";
import { TokenCredentialAuthenticationProvider } from "@microsoft/microsoft-graph-client/authProviders/azureTokenCredentials";
import { DeviceCodeCredential } from "@azure/identity";

const credential = new DeviceCodeCredential({
  clientId: process.env.AZURE_CLIENT_ID!,
  tenantId: process.env.AZURE_TENANT_ID!,
});
const scopes = ["Notes.ReadWrite"];
const authProvider = new TokenCredentialAuthenticationProvider(credential, { scopes });
const client = Client.initWithMiddleware({ authProvider });

Python:

from azure.identity import DeviceCodeCredential
from msgraph import GraphServiceClient

credential = DeviceCodeCredential(
    client_id=os.environ["AZURE_CLIENT_ID"],
    tenant_id=os.environ["AZURE_TENANT_ID"],
)
scopes = ["Notes.ReadWrite"]
client = GraphServiceClient(credentials=credential, scopes=scopes)

Step 2 — Create a Notebook

const notebook = await client.api("/me/onenote/notebooks").post({
  displayName: "Project Notes Q2 2026",
});
// notebook.id is the resource identifier for all child operations
console.log(`Created notebook: ${notebook.id}`);

Notebook names must be unique per user. Attempting to create a duplicate returns 400 Bad Request with code 20117.

Step 3 — Create Section Groups and Sections

// Create a section group (top-level organization)
const group = await client.api(
  `/me/onenote/notebooks/${notebook.id}/sectionGroups`
).post({ displayName: "Engineering" });

// Create a section inside the group
const section = await client.api(
  `/me/onenote/sectionGroups/${group.id}/sections`
).post({ displayName: "Sprint 1" });

// Create a section directly in the notebook (no group)
const standaloneSection = await client.api(
  `/me/onenote/notebooks/${notebook.id}/sections`
).post({ displayName: "Quick Notes" });

Gotcha: The API allows nesting section groups three or more levels deep, but the OneNote desktop app only renders two levels. The web app may show deeper nesting inconsistently. Stick to a maximum of two levels for cross-client compatibility.

Step 4 — Create a Page with XHTML Content

OneNote pages use strict XHTML. Every tag must close. Use data-tag attributes for checkboxes and note tags.

const htmlContent = `<!DOCTYPE html>
<html lang="en-US">
<head>
  <title>Sprint Planning - March 2026</title>
  <meta name="created" content="2026-03-23T10:00:00-05:00" />
</head>
<body>
  <h1>Sprint Planning</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 staging environment</li>
  </ul>
  <table>
    <tr><td>Task</td><td>Owner</td><td>Due</td></tr>
    <tr><td>API integration</td><td>Alice</td><td>March 28</td></tr>
  </table>
  <p>Next meeting: <time datetime="2026-03-30T10:00:00-05:00">March 30</time></p>
</body>
</html>`;

const page = await client.api(
  `/me/onenote/sections/${section.id}/pages`
).header("Content-Type", "text/html").post(htmlContent);
console.log(`Page created: ${page.id} — "${page.title}"`);

XHTML rules that cause silent failures if violated:

All tags must self-close or have closing tags (<br />, not <br>)
No rowspan or colspan on <td> — use separate rows instead
<img> tags must include alt attribute
Content must be UTF-8 encoded

Step 5 — Retrieve Page Content

// Metadata (title, timestamps, parent info) — fast, cacheable
const metadata = await client.api(`/me/onenote/pages/${page.id}`).get();

// Full HTML content — separate endpoint, slower
const content = await client.api(`/me/onenote/pages/${page.id}/content`).get();
// content is a ReadableStream — pipe or buffer it

Important: The HTML returned by GET /content differs from your input. Graph injects data-id attributes on every element, rewrites image src URLs to Graph resource endpoints, and may restructure your table markup. Never diff input vs output HTML for change detection — compare lastModifiedDateTime instead.

Step 6 — Update Page Content (PATCH)

Updates use a JSON array describing targeted changes, not raw HTML replacement:

await client.api(`/me/onenote/pages/${page.id}/content`).patch([
  {
    target: "body",
    action: "append",
    content: "<p>Update: Feature X deployed successfully.</p>",
  },
  {
    target: "#action-items",
    action: "replace",
    content: '<ul><li data-tag="to-do:completed">All items complete</li></ul>',
  },
]);

Valid action values: append, replace, delete, insert, prepend. The target is a CSS selector matching data-id attributes from the output HTML — you must GET /content first to obtain valid targets.

Step 7 — List and Filter Pages with OData

const pages = await client.api("/me/onenote/sections/{sectionId}/pages")
  .select("id,title,lastModifiedDateTime,createdDateTime")
  .top(25)
  .orderby("lastModifiedDateTime desc")
  .get();

for (const p of pages.value) {
  console.log(`${p.title} — Last modified: ${p.lastModifiedDateTime}`);
}

Step 8 — Delete a Page

await client.api(`/me/onenote/pages/${page.id}`).delete();
// Returns 204 No Content on success
// Deleted pages may still appear in LIST results for up to 30 minutes

Output

Successful CRUD operations return:

Create notebook/section/page: 201 Created with resource JSON (includes id, self, createdDateTime)
Get content: 200 OK with XHTML stream
Patch: 204 No Content on success
Delete: 204 No Content on success

Error Handling

Status	Cause	Fix
400	Invalid XHTML, unclosed tags, duplicate notebook name	Validate HTML before sending; check notebook name uniqueness
403	Missing `Notes.ReadWrite` permission, wrong tenant	Verify Azure app permissions and consent status
404	Notebook/section/page deleted or wrong ID	Confirm resource exists with a `GET` before mutation
429	Rate limit hit (600/min per user)	Read `Retry-After` header, wait that many seconds
507	Section page limit exceeded	Archive old pages to a new section; see `onenote-performance-tuning`

Examples

Python — Create notebook and page:

notebook = await client.me.onenote.notebooks.post(
    {"displayName": "Python Notebook"}
)
sections = await client.me.onenote.notebooks.by_notebook_id(
    notebook.id
).sections.post({"displayName": "Notes"})

html = """<!DOCTYPE html>
<html><head><title>Hello from Python</title></head>
<body><p>Created via msgraph-sdk.</p></body></html>"""

page = await client.me.onenote.sections.by_onenote_section_id(
    sections.id
).pages.post(html)

TypeScript — Multipart page with embedded image:

const boundary = "MyPartBoundary";
const body = [
  `--${boundary}`,
  'Content-Disposition: form-data; name="Presentation"',
  "Content-Type: text/html",
  "",
  '<!DOCTYPE html><html><head><title>With Image</title></head>',
  '<body><p>See diagram:</p><img src="name:diagram" alt="Architecture" /></body></html>',
  `--${boundary}`,
  'Content-Disposition: form-data; name="diagram"',
  "Content-Type: image/png",
  "",
  imageBuffer.toString("binary"),
  `--${boundary}--`,
].join("\r\n");

await client.api(`/me/onenote/sections/${sectionId}/pages`)
  .header("Content-Type", `multipart/form-data; boundary=${boundary}`)
  .post(body);
