Register Business Central On-Premises in Microsoft Entra ID for Integrating with Other Services

  • Artikkeli

APPLIES TO Business Central on-premises. Business Central online is automatically configured for integration with other online services.

Note

Azure Active Directory is now Microsoft Entra ID. Learn more

This article describes how to set up Business Central on-premises to use services that are based on Microsoft Azure. There are several services that you can integrate with Business Central on-premises, like Cortana Intelligence and Power BI. Before using the services, you have to register Business Central on-premises in Microsoft Entra ID and give it access to the services. For example, the Sales and Inventory Forecast extension requires that you specify an API key and API URI. Other services require similar information.

Note

In Business Central version earlier than 16.4, the Set up Microsoft Entra ID wizard has an Auto register action. Previously, you could use this action to automatically register Business Central in Microsoft Entra ID. The auto-register functionality has since been removed. Now, you must register the application manually, regardless of your version. The wizard in earlier versions still includes the Auto register link. But the link now opens this article, which guides you through the manual registration.

Prerequisites

  • A Microsoft Entra tenant.

    You need a tenant on Microsoft Entra ID that has at least one user. For more information, see Quickstart: Set up a tenant.

    If the Business Central deployment is using Microsoft Entra authentication, then you already have a tenant with users. See Authenticating Business Central Users with Microsoft Entra ID.

    If your deployment uses NavUserPassword authentication, you need the credentials (sign in email and password) of a user account later in this article.

  • An Azure portal account

    You need an account for accessing the Azure portal. In most cases, this account is the same as your Business Central account. You use this account to access Microsoft Entra tenant via the Azure portal. The account must have application administrator permissions to create and manage app registrations.

Register an application in Microsoft Entra ID

The first task is to use Azure portal to register an application for Business Central on your Microsoft Entra tenant. As part of the registration, you also give the relevant services access to the application. The purpose of registration is to ensure Business Central on-premises and the services know each other's Microsoft Entra ID details.

Tip

The following steps describe how to register a new application. However, if you're using Microsoft Entra authentication, you already have a registered application for Business Central. So instead of registering a new application, you can use the existing application. But if you do, make sure you modify it based on the information in the steps that follow.

  1. Sign in to the Azure portal and register an application for Business Central on-premises in Microsoft Entra tenant.

    1. Follow the general guidelines at Register your application with your Microsoft Entra tenant.

      When you add an application to a Microsoft Entra tenant, you must specify the following information:

      Setting Description
      Name Specify a name for your Business Central on-premises solution, such as Business Central on-premises or Azure Services for Business Central on-premises.
      Supported account types Select Accounts in any organizational directory (Any Microsoft Entra ID directory - Multitenant)

      Note: Business Central doesn't require the organization to be multitenant, not even if this field is set to multitenant.
      Redirect URI Set the first box to Web to specify a web application. Enter the URL for your Business Central on-premises browser client, followed by OAuthLanding.htm, for example: https://localhost/BC240/OAuthLanding.htm https://MyServer/BC240/OAuthLanding.htm or https://cronus.onmicrosoft.com/BC240/OAuthLanding.htm. This file is used to manage the exchange of data between Business Central on-premises and other services through Microsoft Entra ID.

      Important: The URL must match the URL of Web client, as it appears in the browser address of the computer you're working on. For example, even though the actual URL might be https://MyServer:443/BC240/OAuthLanding.htm, the browser typically removes the port number :443.

      When completed, an Overview displays in the portal for the new application.

    2. Copy the Application (Client) ID that was assigned the application and also redirect URL that you specified. You'll use this information later.

  2. Create a client secret for the registered application.

    1. Follow the general guidelines at Add credentials to your web application.

    2. Before you leave the Certificates & secrets page, copy the secret's value to a temporary location. The value isn't accessible once you leave the page. You'll use this key later in your client application code.

  3. Grant the registered application delegated permission to access the required service APIs, like Power BI.

    From the registered application's overview page, select API permissions > Add a permission. Then, use the Request API permissions pane to locate the API and add permissions. For more information, see Add permissions to access web APIs in the Azure documentation.

    Use the following table to help you set the minimum permissions:

    Feature API Permission name Type Description
    All Microsoft Graph User.Read Delegated Sign in and read user profile
    Business Central add-in for Excel The exposed API of the registered app used for authenticating Business Central users. Select this API from the APIs may organization uses tab. Select the Business Central app permission name under Permisssions Delegated Allows users of the add-in for Excel to access the OData web services to read and write data.
    Business Central Add-in for Outlook Microsoft Graph EWS.AccessAsUser.All Delegated Gives the Business Central add-in for Outlook permission to mailbox data in Microsoft 365 (Exchange Online) or Exchange Server.
    Exchange Contact Sync Office 365 Exchange Online Contacts.ReadWrite Delegated Allows the app to create, read, update, and delete user contacts.

    TIP To find Office 365 Exchange Online, type it the search box on the APIs my organization uses tab.
    EWS.AccessAsUser.All Delegated Allows the app to have the same access to mailboxes as the signed-in user via Exchange Web Services.
    OneDrive Integration[1] SharePoint AllSites.FullControl Delegated Have full control of all site collections
    User.ReadWrite.All Delegated Read and write user profiles
    Power BI Integration Power BI Service Report.Read.All Delegated View all reports. Required for viewing Power BI reports in Business Central.
    Workspace.Read.All Delegated View all workspaces. Required for viewing shared Power BI workspaces in Business Central.
    Universal Print integration Microsoft Graph PrinterShare.ReadBasic.All Delegated Read basic information about printer shares. Required for using Universal Print printers.
    PrintJob.Create Delegated Create print jobs. Required for using Universal Print printers
    PrintJob.ReadBasic Delegated Read basic information of user's print jobs. Required for using Universal Print printers.

    1For Business Central 2021 release wave 2 (version 19), the required permissions are different. Use these permissions instead: AllSites.Write, MyFiles.Write, User.Read.All.

  4. Configure consent on each API permission according to your organizations policies.

    Consent is a process where users or admins authorize an application to access a resource, like a user's profile or mailbox, depending on the service. When a user attempts to sign in to the registered app for the first time, the app requests permission, and the user must accept to continue. As an admin, you can consent on behalf of all users, so they don't have to. To learn more, go to More on API permissions and admin consent and Introduction to permissions and consent.

  5. If this is a new registered app, and not an update to an existing one, go to the next task to set it up in Business Central.

Set up the registered application in Business Central

After you create the application registration, the next task is to configure the Business Central tenant to use it. You need the following information about the application registration: redirect URL, application (client) ID, and client secret.

Note

Don't complete this task for configuring OneDrive integration with Business Central 2022 release wave 1 (version 20) and earlier. Instead, see Configuring Business Central On-Premises for OneDrive in the business functionality help.

  1. In the top-right corner, choose the Tell me. icon, enter Assisted Setup, and then choose the related link.

  2. Select Set up your Microsoft Entra accounts, then Next.

    The Connect With Azure page opens.

  3. In the Redirect URL field, make sure the URL matches the redirect URL that's assigned the registered Business Central application in Microsoft Entra ID.

  4. In the Application ID field, specify the application (client) ID of the Business Central application in Microsoft Entra ID that you copied in the previous task.

  5. In the Key field, specify the value of the client secret that's used by the Business Central application in Microsoft Entra ID.

  6. Choose Next.

    If you're using NavUserPassword authentication, you're prompted to sign in to the Microsoft Entra tenant. In this case, enter the sign-in email and password of a valid account.

Unless you see an error message, you're now done. The Business Central on-premises solution is registered and ready to connect to services such as Cortana Intelligence, or embedding Power BI in Business Central.

Next step

The first time a feature that uses the registered application is accessed from Business Central, consent must be given to the Azure service. Consent can only be given by a Microsoft Entra admin user account. So, after you set up the registered the application in Business Central, make the initial connection to these services and give consent. As an example, see Connect to Power BI from Business Central- one time only.

Fixing problems

This section provides solutions to problems that might occur.

Sorry, but we're having trouble signing you in

When you try to connect, you get a message similar to the following text:

AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application: '1111111-aaaa-2222-bbbb-333333333333'

To fix this issue, verify that the Reply URL in the Setup Microsoft Entra ID page is correct. It must match the Reply URL set on the registered app in Microsoft Entra ID.

Couldn't connect to service

After authorizing the Azure service, you get a message similar to the following text:

We couldn't connect to [service name] using your Microsoft Entra application registration. Run the Set Up Microsoft Entra ID assisted setup again, and make sure all values are set correctly.

This issue indicates there's a problem with the configuration of the Azure registered application used by the service. The problem is typically caused by incorrect values for either the Redirect URL, Application ID, or Key fields in the application registration. A common problem deals with the redirect URLs. Make sure the Redirect URL matches the redirect URL in the Azure portal and the URL of the Web client. To fix this issue, run the Set Up Microsoft Entra ID assisted setup and compare the values with the app registration in Azure.

Problem consenting to the Microsoft Entra (Azure) services for initial connection

While consenting to the services for the initial connection, you keep getting prompted to consent instead of connecting, there may be a problem with the reply URL that used in the Set up your Microsoft Entra accounts assisted setup guide. The first part of the reply URL, before OAuthLanding.htm, should exactly match what appears in your browser URL when you open the Business Central web client. For example, if the browser URL is https://localhost/BC240 on your computer, then the reply URL you provide must be https://localhost/BC240/OAuthLanding.htm. The reply URL must also be included in the app you registered in Microsoft Entra ID previously in this article.
