Establishing a Connection

Configure a Connection Profile

From the CData ribbon, click Get Data and select From Microsoft Dataverse connection/s to launch the CData Query window. To setup a new connection, you will have to click the New Microsoft Dataverse Connection button. Here you can set the connection settings, test the connection, and save the connection profile.

Schema

Microsoft Dataverse supports schema values of 'System' and 'Entities' and can be set using the Schema property.

Using 'System' for Schema property uses the Web API to query entities/tables.

Using 'Entities' for Schema property uses the EntityDefinitions entity set path and retrieves information about EntityMetadata EntityType entities/tables. This will often result in more user friendly names, though requires extra metadata requests.

Connecting to Microsoft Dataverse

To authenticate to the Microsoft Dataverse source, you should first set the OrganizationUrl to the URL of the organization you are connecting to, such as https://[organization].crm.dynamics.com.

Azure AD

Azure AD is a connection type that leverages OAuth to authenticate. OAuth requires the authenticating user to interact with Microsoft Dataverse using an internet browser. The add-in facilitates this in several ways as described below. Set your AuthScheme to AzureAD. The rest of the AzureAD flows assume that you have done so.

Desktop Applications

CData provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See Creating a Custom OAuth Application for information about creating custom applications and reasons for doing so.

For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.

After setting the following connection properties, you are ready to connect:

OAuthClientId: (custom applications only) Set this to the client Id in your application settings.
OAuthClientSecret: (custom applications only) Set this to the client secret in your application settings.
CallbackURL: Set this to the Redirect URL in your application settings.

When you connect the add-in opens the OAuth endpoint in your default browser. Log in and grant permissions to the application.

Client Credentials

Client credentials refers to a flow in OAuth where there is no direct user authentication taking place. Instead, credentials are created for just the app itself. All tasks taken by the app are done without a default user context. This makes the authentication flow a bit different from standard.

Client OAuth Flow

All permissions related to the client oauth flow require admin consent. This means the app embedded with the CData Excel Add-In for Microsoft Dataverse cannot be used in the client oauth flow. You must create your own OAuth app in order to use client credentials. See Creating a Custom OAuth Application for more details.

In your App Registration in portal.azure.com, navigate to API Permissions and select the Microsoft Graph permissions. There are two distinct sets of permissions - Delegated and Application permissions. The permissions used during client credential authentication are under Application Permissions. Select the applicable permissions you require for your integration.

You are ready to connect after setting one of the below connection properties groups depending on the authentication type.

Client Secret
- InitiateOAuth: Set this to GETANDREFRESH. You can cuse InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- AzureTenant: Set this to the tenant you wish to connet to.
- OAuthGrantType: Set this to CLIENT.
- OAuthClientId: Set this to the Client Id in your app settings.
- OAuthClientSecret: Set this to the Client Secret in your app settings.
Certificate
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- AzureTenant: Set this to the tenant you wish to connect to.
- OAuthGrantType: Set this to CLIENT.
- OAuthClientId: Set this to the Client Id in your app settings.
- OAuthJWTCert: Set this to the JWT Certificate store.
- OAuthJWTCertType: Set this to the type of the certificate store specified by OAuthJWTCert.

Authentication with client credentials will take place automatically like any other connection, except there will be no window opened prompting the user. Because there is no user context, there is no need for a browser popup. Connections will take place and be handled internally.

Azure Service Principal

Azure Service Principal is role-based application-based authentication. This means that authentication is done per application, rather than per user. All tasks taken on by the application are executed without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.

For information about how to set up Azure Service Principal authentication, see Creating a Custom OAuth Application.

Managed Service Identity (MSI)

If you are running Microsoft Dataverse on an Azure VM and want to leverage MSI to connect, set AuthScheme to AzureMSI.

User-Managed Identities

To obtain a token for a managed identity, use the OAuthClientId property to specify the managed identity's "client_id".

When your VM has multiple user-assigned managed identities, you must also specify OAuthClientId.

Connection Properties

The Connection properties describe the various options that can be used to establish a connection.

Managing Connections

After successfully authenticating to Microsoft Dataverse you will be able to customize the data you are importing. To learn more about this, see Managing Connections.
