Set up the Dynamics 365 Business Central integration
Explore our API integration with Dynamics 365 Business Central.
Before you can access data from customers who use Dynamics 365 Business Central, you need to set up the integration in the Codat Portal. You'll need to:
- Register and configure your Business Central application and then generate your client ID
- Generate your client secret
- Update access permissions
- Add your secure keys to the Codat Portal
- Enable the Dynamics 365 Business Central integration in the Codat Portal
We recommend you test your integration using a trial Business Central account before production use.
During the SMB linking process, the Dynamics 365 Business Central extension package must be successfully installed to the user's account in order for the integration to function. The extension is published by Codat.
For more information, see Extension installation process below.
A Dynamics 365 Business Central license is required to use our integration. At a minimum, you'll need a Dynamics 365 Business Central Essentials license.
For more information, see the Business Central pricing page for your region.
We also assume that your organization already has its Microsoft account configured, and the domain name in your account email has been DNS-verified. If you are creating an account for the very first time, you may need to create a tenant for your organization and verify the domain.
Register your application
Register your Business Central application on the Microsoft Azure portal.
Sign in to the Microsoft Azure portal.
If you already have a Dynamics 365 Business Central account, use those account details to sign in. If not, you can create an account.
To gain access to any Azure configuration that your company has already set up—for example, for user authentication—enter your company email when you sign up.
If your organization is using Azure Active Directory (Azure AD) to control access to Dynamics 365 Business Central, ask your Azure AD administrator to add your account to the correct group.Unable to create account
Contact your Business Central administrator if you can't create a new Business Central account. They might have disabled this feature.
After you've signed in, select Azure Active Directory on the home page or left menu.
Details of the tenant that your account is connected to are displayed.
You might have access to more than one tenant, so check the details carefully. If you don't see the expected information, select Switch tenant, then select the right tenant.
Select App registrations in the left menu, then click New registration.
Enter the following details:
Name: Enter a short name for your application. Your customers will see this name when they authorize your connection to their accounting system.
Supported account types: Select Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox). This allows Codat to access data in Dynamics 365 Business Central.
Redirect URI: Select Web, then enter the following URL:
Azure registers your application details and generates your client ID as shown the screenshot below. You'll need this later, so either copy the details now or keep the page open in a separate browser tab.

Generate and retrieve your client secret
In the Azure Portal:
Select Certificates & secrets in the left menu.

Select API permissions in the left menu.
Under Configured permissions, click Add a permission.

Extension installation process
Before you link their accounts, we recommend you inform your customers about the installation and linking process for the Dynamics 365 Business Central extension.
During the linking process, Codat installs a Dynamics 365 Business Central extension into the customer's Business Central environment. This extension has the following attributes:
- Description/Publisher: Codat
- Name: App Link
The extension might take 10–20 minutes to install and the installation page might refresh repeatedly while the installation is in progress. A message displays when the extension has been successfully installed.
Be aware that fetch errors might occur during the installation.
If the latest version of the extension is uninstalled or unpublished, Codat is unable to retrieve all the required data from the accounting platform.
