OneNote is a popular note-taking tool that's available online and on many mobile and tablet platforms. By integrating your apps with OneNote, it's easier than ever to create empowering apps on your favorite platforms and reach millions of users worldwide.

Take advantage of OneNote's notebook, section, and page hierarchy and easy-to-use API to help your users plan and organize ideas and information.

Note

When you use the OneNote API, you agree to the Microsoft API terms of use.

Platform overview

The OneNote service runs on the Microsoft cloud and provides a RESTful interface for programmatic access to OneNote content. The OneNote API is lightweight and simple—it's built on JSON, HTML, and OData, so you can use it with any language or platform that supports HTTP requests.

Here's a simple view of the OneNote API development stack.

First, your user must be authenticated and grant access to your app. Then you get an access token that you use to interact with OneNote content. In addition to CRUD support for OneNote resources, the API also provides capabilities such as optical character recognition (OCR), full-text search, and business card extractions.

Using the OneNote API

To use the OneNote API, you send HTTP requests to specific endpoints off OneNote's service root URL:

https://www.onenote.com/api/{version}/{location}/notes/..

You can use the OneNote API to do things like create, view, and manage pages in personal, site, and group notebooks. To give you an idea of how the API works, here's a simple POST request that creates a page in the current user's default notebook.

If successful, the request returns the following response—in this case an OData representation of the new page in JSON format.

See Create pages for a closer look at POST pages requests.

AuthPass is a stand alone password manager with support for the popular and proven Keepass (kdbx 3.x AND kdbx 4.x 🎉️) format. Store your passwords, share across all your devices and easily find. AuthPass isn't just biometric, it's true Two-Factor Authentication. Login requires your fingerprint and YOUR hardware token so no one else can use it. Protected Credentials. Tokens process all fingerprint authentications securely on-device. AuthPass never sees or stores ANY biometric data. Authpass autofill. One of them can be AuthPass, or it is also possible to use another type of password manager. When thinking of a strong key, you probably need a manager of this type of encryption to protect personal documents. This even more so at a time where you don't have the creative idea of taking care of the profiles that you keep in your possession.

Why create OneNote apps?

Integrate OneNote to create apps that people will love. You can use the OneNote API to create and manage notes, lists, pictures, files, and more in OneNote notebooks.

Collect and organize notes and ideas

Use OneNote as a canvas where users can add and arrange their content. The OneNote API makes it easy to write apps so students can take notes and do research, families share plans and ideas, shoppers share pictures—all the things that interest people most. Your app can grab the information people want, send it to OneNote, and then help them organize it.

Capture information in many formats

Capture HTML, embed images (sourced locally or at a public URL), video, audio, email messages, and other common file types. OneNote can even render webpages and PDF files as snapshots. The OneNote API supports a set of standard HTML and CSS for OneNote page layout, so you can use tables, inline images, and basic formatting to get the look you want.

Use the OneNote ecosystem to enhance your core scenarios

Tap into other powerful OneNote API features. The API runs OCR on images, supports full-text search, auto-syncs clients, processes images, and extracts business card captures and online product and recipe listings. Use OneNote as your digital memory store in the cloud for notes and lightweight media, or as a data feed for domain-specific data.

Reach millions of OneNote users on all major platforms

Use OneNote to increase your app usage. Pre-installed on new Windows devices, available for popular platforms, on the web as OneNote Online, and part of Office 365—100+ million people worldwide actively use OneNote. When you publish apps that leverage the feature-rich OneNote environment, the cross-platform market potential is simply too big to ignore.

SDKs for OneNote development

OneNote apps can use the OneDrive API SDK to get the access tokens that are required for all requests to the OneNote API. The SDK makes authentication easier for you. You just provide your identity information and integrate a few calls, and the SDK handles everything from sign in and consent to getting, storing, and refreshing tokens. Then, you can make REST calls to the OneNote API. Our iOS tutorial shows how you can use the SDK in a OneNote app.

All versions of the SDK support Microsoft account authentication (for consumer notebooks), and some also support Azure Active Directory (for enterprise notebooks). See the OneDrive documentation for the current list of supported platforms.

Note

The OneDrive API SDK replaces the Live SDK. The Live SDK is deprecated but will continue to support existing OneNote applications that use it. For new development, use the OneDrive API SDK.

At some point, we may provide libraries that both handle authentication and support native calls to the OneNote API, but for now you can use the OneDrive API SDK.

Alternatively, enterprise apps can use the Active Directory Authentication Library (ADAL) to access Office 365 and SharePoint-hosted notebooks. You might consider using ADAL directly if there's no SDK available for your platform or if you want more control over the auth process. Our ASP.NET MVC tutorial shows how you can use ADAL in a OneNote app.

Important

To interact with OneNote content and resources, you should always use the OneNote API. Don't use the OneDrive API.

What's changed

The following entries highlight changes made to the OneNote API and documentation during the past year:

July 2016

• Added the Work with staff notebooks topic.
• Documented support for embedded videos.

May 2016

• Added page preview support. Use the ./pages/{id}/preview endpoint to get text and image preview content for a page. Read the Page preview API blog post to learn more.
• Documented support for the ./users/{id}/notes/ location, which enables access to OneNote content that the specified user (in the URL) has shared with the current user. Enterprise notebooks only.
• Added permission management APIs that allow you to set access permissions on a notebook, section group, or section. Enterprise notebooks only.
• Added new class notebook operations: Insert sections from other notebooks, add a Teacher Only section group, delete class notebooks, create class notebooks in a specified language, send an email notification for a new class notebook. Enterprise notebooks only.
• Added support for the <pre> element in page HTML content. Now, content captured from sites like MSDN and StackOverflow renders with proper code formatting.

March 2016

• Released GET /pages/{id}/content?preAuthenticated=true to production. When the preAuthenticated=true query string option is used to retrieve page content, the output HTML includes public URLs to the image resources on the page. These pre-authenticated URLs are valid for one hour. See One time Authentication for Public Resource.
• Released PATCH /sections/{id} to production. This lets you rename a section by sending an application/json content type in the message body, like this: { 'name': 'New section name' }

February 2016

• Added the Subscribe for webhooks and Work with class notebooks topics. Webhooks is currently supported only for consumer notebooks on OneDrive.

January 2016

• Turned on throttling. Learn more about OneNote API throttling and best practices to avoid it.
