How to Get a SharePoint User Identity or Token for Embedded Apps
Question details
A developer needs to obtain a signed identity token or access token via JavaScript to recognize and map authenticated SharePoint users within an embedded application.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Developing an application embedded inside a SharePoint page that requires seamless user authentication and account mapping.
- Observed behavior
- The user is seeking the correct Microsoft Entra ID authentication flow or JavaScript method to retrieve the user's token securely, which requires specialized developer guidance.
Obtaining access tokens for embedded applications requires administrator access to your Microsoft Entra ID (formerly Azure AD) tenant and developer privileges in SharePoint. Ensure you have the necessary permissions to register enterprise applications and configure API permissions before modifying your application code.
Seek Guidance on the Microsoft Q&A Developer Forum
Since obtaining and validating signed identity tokens involves complex developer integrations, the best place to find expert guidance is the Microsoft Q&A developer forums.
Standard end-user support communities cannot resolve code-level integration issues or authentication flows for embedded applications. Office development topics require specialized insight into Microsoft Entra ID and token validation methods.
Open your web browser and go to the official Microsoft Q&A platform at learn.microsoft.com/en-us/answers/.
When posting your question, use specific development tags such as 'SharePoint Development', 'Microsoft Graph', or 'Microsoft Entra ID' to ensure it reaches the right developer community.
Include details about your JavaScript implementation (e.g., MSAL.js), the current authentication flow you are attempting, and exactly how the application is embedded within the SharePoint page.
Switch to WPS Office for a Seamless Productivity Experience
While SharePoint handles complex web application embedding and developer integrations, managing everyday documents shouldn't require IT expertise. If you need a reliable, lightweight desktop suite for daily tasks, WPS Office is a perfect choice, offering excellent compatibility without the heavy enterprise overhead.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button for your operating system.
- 2. Install the Software: Run the downloaded setup file and follow the simple on-screen instructions to complete the installation.
- 3. Open Your Documents: Launch WPS Office and instantly open your existing Microsoft Office files without any formatting loss.
Frequently Asked Questions
What is a SharePoint identity token used for?
A SharePoint identity token is used to securely authenticate and verify the identity of a user interacting with a SharePoint add-in or embedded application. This allows the custom application to map the authenticated Microsoft 365 user to its own internal user database securely.
Can I get a SharePoint access token using only JavaScript?
Yes, developers typically use the Microsoft Authentication Library (MSAL.js) in their JavaScript code to acquire access tokens silently for users who are already signed into Microsoft 365, utilizing the OAuth 2.0 implicit grant or authorization code flow.
Why shouldn't I post SharePoint development questions in standard user forums?
Standard user forums are monitored by support agents trained in general troubleshooting and software usage. Developer questions require specialized knowledge of Microsoft Entra ID, REST APIs, and authentication tokens, which are supported exclusively by engineers and developers on the Microsoft Q&A platform.
