What is Microsoft Graph API

Microsoft Graph API is a comprehensive RESTful API provided by Microsoft that allows developers to access a wide range of Microsoft 365 services and data, including Office 365, Azure Active Directory, SharePoint, OneDrive, Outlook, and more. It serves as a unified gateway to access and interact with various Microsoft services and their underlying data.

With Microsoft Graph API, developers can build applications that leverage the rich functionality and data available across Microsoft 365 services. It provides a consistent and efficient way to retrieve, create, update, and delete data in a standardized manner, simplifying the development process and reducing the need for multiple API calls.

Through Graph API, developers can access resources such as users, groups, files, calendars, contacts, messages, and other entities within Microsoft 365. They can perform tasks like retrieving user profiles, accessing documents, sending emails, creating events, managing permissions, and more.

Graph API supports a variety of authentication mechanisms, including Azure Active Directory (Azure AD), OAuth 2.0, and Microsoft account authentication. This ensures secure access to Microsoft 365 resources and protects user data.

By integrating Microsoft Graph API with SAP UI5, developers can unlock powerful capabilities, such as retrieving and manipulating data from Microsoft 365 services, enabling collaboration features, accessing user information, and integrating with various business workflows. It provides seamless connectivity between SAP applications and Microsoft services, facilitating enhanced productivity and enriched user experiences. Read more here.

Steps to Create Authorization Key of Graph API

To create an authorization key (also known as an access token) for Microsoft Graph API, you need to follow these steps:

1. Register your application: Start by registering your application in the Azure portal. This registration enables your application to authenticate and authorize access to Microsoft Graph API. Navigate to the Azure portal (https://portal.azure.com/) and sign in with your Azure account.

Microsoft Azure Portal

2. Create an Azure AD application: In the Azure portal, go to the “Azure Active Directory” section and select “App registrations” (or “App registrations (Legacy)” for older versions). Click on the “New registration” (or “New application registration”) button to create a new application.

Create Azure AD User

3. Provide application details: Fill in the required details for your application, such as a name, supported account types, and redirect URI (if applicable). The redirect URI is the URL where users are redirected after authentication.

Certificate & Secrets

4. Configure API permissions: In the application settings, navigate to the “API permissions” (or “Required permissions”) section. Click on the “Add a permission” button and select the Microsoft Graph API.

5. Select required permissions: Choose the required permissions based on the operations your application needs to perform. For example, if you need to read user profiles, select the appropriate User.Read scope. Click on the “Grant admin consent” button to grant these permissions for your application (if you have the necessary permissions).

6. Obtain the authorization code: To obtain an authorization code, construct the authorization URL by specifying the appropriate scopes and redirect URI. Users will be prompted to sign in and grant consent to your application. After successful authentication and consent, the authorization code will be included in the redirected URL.

7. Exchange authorization code for an access token: Using the authorization code, make a POST request to the token endpoint of Microsoft Graph API. Include the necessary parameters like client ID, client secret (if applicable), redirect URI, and authorization code. The response will contain an access token, which is the authorization key you can use to make authenticated requests to Microsoft Graph API.

Note: The specific implementation details may vary based on your programming language and platform. You can refer to the official Microsoft Graph API documentation for more detailed instructions and code examples specific to your scenario.

Remember to handle the authorization key securely and refresh it as needed, following the recommended practices to ensure the security of your application and user data.
