I was building a standalone HTML page which retrieves the Account records from Dynamics 365 and show them in a table.

As a prerequisite, I registered the application in Azure Active Directory’s ‘App registrations’.

Also configured the Application details in my HTML page

var organizationURI = “https://{orgname}.crm.dynamics.com”; //The URL to connect to CRM (online)
var tenant = “{Azure Tenant Name}.onmicrosoft.com”; //The name of the Azure AD organization you use
var clientId = “{Application ID}”; //The ApplicationId you got when you registered the application
var pageUrl = “http://localhost”; //The URL of your HTML page in your development environment.

After all the configuration, I was getting below error during the authentication

The reply address “http://…..” does not match the reply address configured for the application.

Reason and Fix:

• There must be a ‘Return URL’ configured with your application URL (i.e., HTML url in my case).
• To configure the ‘Return URL’
  • Connect to ‘Azure Active Directory’ –> App registrations
  • Select your configured Application
  • Under ‘Settings’, click on ‘Reply URLs’
  • Add your application URL (i.e., HTML url in my case)

• Rerun the Application and you should be able to connect and get Accounts
