Prerequisites

• Microsoft Dynamics CRM Online 2016 Update
• You must have a Microsoft Dynamics 365 (online) system user account with administrator role for the Microsoft Office 365.
• A Microsoft Azure subscription for application registration. A trial account will also work.

Register the application

1.  Sign in to Azure - https://ms.portal.azure.com , You must use an account in the same Office 365 subscription (tenant) as you intend to register the app with. You can also access the Microsoft Azure portal through the Office 365 admin center by expanding the ADMIN item in the left navigation pane and selecting Azure AD.

2. Click on New Application registration , Provide any Name , Choose the Application Type as Web App/Web API and Sign-on URL that later translates to Home Page Url also called as Redirect Url is the URL which the user should be redirected to after they sign in and this field can be changed at later point of time.

3. Once created, Click on Manifest and change the property from false to true "oauth2AllowImplicitFlow": true and Save the Manifest file , Else it would throw the error as below

"aadsts70005: response_type 'token' is not enabled for the application"
