Are you struggling to get Microsoft Graph API login with Single Sign-On (SSO) to work? You’re not alone! In this article, we’ll dive into the common issues and provide step-by-step solutions to get you up and running in no time.
What is Microsoft Graph API?
Microsoft Graph API is a powerful tool that allows developers to access Microsoft services and data, including Azure Active Directory (AAD), Office 365, and more. With Graph API, you can build custom applications that integrate seamlessly with Microsoft products, enhancing user experience and productivity.
What is Single Sign-On (SSO)?
Single Sign-On (SSO) is an authentication mechanism that enables users to access multiple applications and services with a single set of login credentials. In the context of Microsoft Graph API, SSO allows users to access your application without having to re-enter their credentials, providing a seamless and secure experience.
The Problem: Microsoft Graph API Login with SSO not working
So, you’ve set up your Microsoft Graph API, configured SSO, and… nothing. Your users are still prompted to enter their credentials, and you’re left scratching your head. Don’t worry; we’ve got you covered! Let’s explore the common issues and their solutions.
Issue 1: Incorrect Azure AD Configuration
Azure Active Directory (AAD) is the foundation of Microsoft Graph API’s SSO capabilities. If your AAD configuration is incorrect, SSO won’t work. Here’s what to check:
- Ensure you have the correct Azure AD tenant ID and client ID.
- Verify that you have created an Azure AD application with the correct permissions.
- Check that you have configured the correct redirect URI in your Azure AD application.
Azure AD Configuration Checklist:
- Tenant ID: _______________
- Client ID: _______________
- Redirect URI: _______________
- Permissions: _______________
Issue 2: Incorrect Microsoft Graph API Configuration
Misconfigured Microsoft Graph API settings can also prevent SSO from working. Here’s what to check:
- Verify that you have enabled the correct permissions for your Microsoft Graph API application.
- Check that you have configured the correct authentication flow (e.g., authorization code flow or implicit flow).
- Ensure you are using the correct Microsoft Graph API endpoint (e.g.,
https://graph.microsoft.com/v1.0
).

- Permissions: _______________
- Authentication Flow: _______________
- Endpoint: _______________
Issue 3: Token Acquisition and Validation
Token acquisition and validation are critical steps in the SSO process. Here’s what to check:
- Verify that you are acquiring an access token using the correct Azure AD endpoint (e.g.,
https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token
). - Check that you are validating the access token using the correct token validation endpoint (e.g.,
https://graph.microsoft.com/v1.0/me
). - Ensure you are handling token renewal and refresh correctly.
Token Acquisition and Validation Checklist:
- Token Endpoint: _______________
- Token Validation Endpoint: _______________
- Token Renewal and Refresh: _______________
Issue 4: CORS Configuration
Cross-Origin Resource Sharing (CORS) configuration can also impact SSO functionality. Here’s what to check:
- Verify that you have configured CORS correctly in your Azure AD application.
- Check that you have allowed the correct origins and methods in your CORS configuration.
CORS Configuration Checklist:
- Origins: _______________
- Methods: _______________
Solution: Step-by-Step Guide to Fixing Microsoft Graph API Login with SSO
Now that we’ve covered the common issues, let’s walk through a step-by-step guide to fixing Microsoft Graph API login with SSO:
-
Step 1: Verify Azure AD Configuration
- Log in to the Azure portal and navigate to your Azure AD application.
- Check that you have the correct tenant ID, client ID, and redirect URI.
- Update your Azure AD configuration if necessary.
-
Step 2: Verify Microsoft Graph API Configuration
- Log in to the Microsoft Graph API portal and navigate to your application.
- Check that you have enabled the correct permissions and configured the correct authentication flow.
- Update your Microsoft Graph API configuration if necessary.
-
Step 3: Acquire and Validate Tokens
- Use the correct Azure AD endpoint to acquire an access token.
- Validate the access token using the correct token validation endpoint.
- Handle token renewal and refresh correctly.
-
Step 4: Configure CORS
- Configure CORS in your Azure AD application.
- Allow the correct origins and methods in your CORS configuration.
-
Step 5: Implement SSO in Your Application
- Implement SSO using the Microsoft Graph API SDK or a third-party library.
- Use the acquired and validated token to authenticate users in your application.
Conclusion
Microsoft Graph API login with SSO not working? Don’t worry! By following this comprehensive guide, you should be able to identify and fix the common issues preventing SSO from working. Remember to verify your Azure AD and Microsoft Graph API configurations, acquire and validate tokens correctly, configure CORS, and implement SSO in your application. With these steps, you’ll be well on your way to providing a seamless and secure user experience with Microsoft Graph API and SSO.

Frequently Asked Question
Get the most out of Microsoft Graph API login with SSO – we’ve got the answers to your burning questions!
Why is my Microsoft Graph API login with SSO not working?
First, check that you’ve correctly configured the Azure AD app and granted the necessary permissions. Ensure that the Azure AD app ID and secret are correct, and that the Azure AD tenant ID is properly set. If you’re still stuck, try clearing the cache and retrying the login process.
Do I need to register my application in Azure AD to use Microsoft Graph API with SSO?
Yes, to use Microsoft Graph API with SSO, you need to register your application in Azure AD. This will generate an app ID and secret, which are required for authentication. Follow the Azure AD app registration guide to get started!
How do I handle expired or revoked access tokens for Microsoft Graph API with SSO?
When an access token expires or is revoked, your application should handle it by refreshing the token or re-authorizing the user. You can use the token refresh endpoint to obtain a new access token. For revocation, implement a token revocation handler to detect and handle token revocation.
What permissions do I need to grant to use Microsoft Graph API with SSO?
The required permissions depend on the specific Microsoft Graph APIs you’re using. Check the Microsoft Graph documentation for the specific API you’re calling, and grant the necessary delegated or application permissions. Don’t forget to consent to the permissions in Azure AD!
Can I use Microsoft Graph API with SSO for both Azure AD and Microsoft accounts?
Yes, Microsoft Graph API supports both Azure AD and Microsoft accounts. When registering your application in Azure AD, select the “Accounts in any organizational directory” option to allow both Azure AD and Microsoft accounts to authenticate. This will enable SSO for both types of accounts.
