Client Key – The client secret key is sent along with a Client ID when authenticating to Azure AD to call a web API. Resource Uri – The resource Uri to the Power BI resource to be authorized. [https://analysis.windows.net/powerbi/api] Authority Uri – The authority Uri is an Azure resource that takes a client id to get an access token. [https://login.windows.net/common/oauth2/authorize/] Redirect Url – A Redirect Url for the web app url. The Azure AD service redirects back to the web app url with an authentication code. 26/09/2015 | SQL Saturday #434 – Holland
