Windows Azure Active Directory Graph Prerequisites
To start developing your cloud applications that consume Windows Azure AD Graph, you need to make sure you met the following prerequisites:
An Internet connection: Windows Azure AD Graph requires internet connectivity.
Windows Azure Subscription: You need to have a valid Windows Azure subscription. You can get a 90 day free trial here: Windows Azure Free Trial. Alternatively, you can subscribe to Windows Azure AD as an Office 365 tenant. For more information about Windows Azure subscriptions, see this topic on WindowsAzure.com: Sign Up for Windows Azure as an Organization
Windows Azure AD Tenant Permissions to Access Directory Data: In order to call the Graph API against a directory tenant in Windows Azure AD, a tenant administrator must grant access. For more information about granting access, see Using the Graph API to Query Windows Azure AD.
The following prerequisites are optional:
Microsoft Office 365 Windows PowerShell Cmdlets (Optional): The Microsoft Office 365 Windows PowerShell Cmdlets can be used by an administrator to perform administrative tasks on Windows Azure AD directory entities. For example, an administrator can use these cmdlets to manage their tenant's users, service principals, and domains. While it is not a strict requirement to install the cmdlets to use Windows Azure AD Graph, if you will be managing service principals you must use these cmdlets to do so. Also, many of the how-to procedures in this documentation create a user in your tenant's directory and you may find the Office 365 cmdlets helpful in removing the user after running the example. For more information about these cmdlets, see the following topic: Windows Azure AD PowerShell Cmdlets
Windows Azure AD Graph Code Samples (Optional): While it is not required, we recommend downloading the sample applications that demonstrate the capabilities of the Windows Azure AD Graph API. For more information about the code samples available for Windows Azure AD Graph, see Windows Azure AD Graph Code Samples Index.
