Access Token Essentials

Client ID, Secret ID, and Tenant ID

When registering an application on Azure for Graph API integration, you'll receive essential credentials:

Client ID: A unique identifier for your application.

Secret ID: A confidential key used for authentication.

Tenant ID: Identifies the organization that owns the application.

These IDs authenticate your application's identity and grant access to Microsoft Graph API resources.

Redirect URI

During app registration, you specify a Redirect URI. This URI serves as a callback endpoint where the authorization server redirects users after authentication. It plays a vital role in the OAuth 2.0 authorization flow, facilitating the exchange of authorization codes for access tokens.

---------------------------------------------------------------------------------------------------------------------------

1. Client ID, Secret ID, and Tenant ID

These credentials are obtained during the registration of your application in the Azure portal:

Client ID: After creating an Azure AD application, navigate to the "App registrations" section in the Azure portal. Select your application to view its details, including the Client ID.

Secret ID: Also known as the Application Secret or Client Secret, you can generate this key under the "Certificates & secrets" section within your application's settings in the Azure portal.

Tenant ID: This ID represents the Azure AD tenant associated with your organization. You can find it in the Azure portal by navigating to "Azure Active Directory" > "Properties" and locating the Directory (tenant) ID.

2. Redirect URI

During app registration, you specify a Redirect URI where the authorization server redirects users after authentication. You can define this URI based on your application's requirements. Typically, it's a route within your application where the authorization code is received and processed.

3. Obtaining Access Tokens

To retrieve access tokens for Microsoft Graph API:

Authentication Flow: Implement OAuth 2.0 authorization flow in your application, which involves redirecting users to the Microsoft login page for authentication and consent.

Authorization Request: Construct an authorization request URL with parameters such as Client ID, Redirect URI, and requested scopes.

User Authentication: Users log in with their Microsoft credentials and grant consent for your application to access their data.

 Access Token Retrieval: After successful authentication and consent, the authorization server issues an authorization code to your Redirect URI. Exchange this code for an access token by sending a token request to the token endpoint, including Client ID, Secret ID, Redirect URI, and Tenant ID.

Cautionary Note

Relying solely on direct token generation outside the OAuth 2.0 flow can lead to security risks and issues. It's essential to adhere to best practices by following the OAuth 2.0 authorization flow and obtaining access tokens directly from Microsoft Graph API.

By navigating through the Azure portal and integrating these credentials and flows into your application, you can ensure secure and reliable access to OneNote and other Microsoft services via Microsoft Graph API.
