Configure a Connection Profile

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

Connecting to Azure Cosmos DB

Azure Cosmos DB supports connecting and authenticating by Account Key, through Azure AD, or through Azure Service Principal.

Account Key

Log in to the Azure Portal, select Azure Cosmos DB, and select your account.

Set the following to authenticate:

• AccountEndpoint: The Cosmos DB account URL. Set this to the URI value found in the Settings > Keys blade of the Cosmos DB account.
• AccountKey: A master key token or a resource token for connecting to Azure Cosmos DB. Set this to the PRIMARY KEY value found in the Settings > Keys blade of the Cosmos DB account.
• TokenType: (optional). Set this to "master" (the default value) if you are using a Master Token, which is a full permissions token generated during account creation. Otherwise, set this property to "resource" if you are using a Resource Token, which is a custom permissions token generated when a database user is set up.

Entra ID (Azure AD)

Note: Microsoft has rebranded Azure AD as Entra ID. In topics that require the user to interact with the Entra ID Admin site, we use the same names Microsoft does. However, there are still CData connection properties whose names or values reference "Azure AD".

Microsoft Entra ID is a multi-tenant, cloud-based identity and access management platform. It supports OAuth-based authentication flows that enable the add-in to access Azure Cosmos DB endpoints securely.

Authentication to Entra ID always requires that you first create and register a custom OAuth application. This enables your application to define its own redirect URI, manage credential scope, and comply with organization-specific security policies.

For full instructions on how to create and register a custom OAuth application, see Creating an Entra ID (Azure AD) Application.

After setting AuthScheme to AzureAD, the steps to authenticate vary, depending on the environment. For details on how to connect from desktop applications, web-based workflows, or headless systems, see the following sections.

Desktop Applications

During the registration of your custom application, as described in Creating an Entra ID (Azure AD) Application, record the following values: client Id, client secret, and callback URL (redirect URI).

Then, set the following connection properties:

• AuthScheme: AzureAD.
• InitiateOAuth:
  • GETANDREFRESH: Use for the initial login. Launches the login page and saves tokens.
  • REFRESH: Use this setting when you have already obtained valid access and refresh tokens. Reuses stored tokens without prompting the user again.
• OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
• OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
• CallbackURL: A redirect URI you defined during application registration.

After authentication, tokens are saved to OAuthSettingsLocation. These values persist across sessions and are used to automatically refresh the access token when it expires, so you don't need to log in again on future connections.

Azure Service Principal

Note: Microsoft has rebranded Azure AD as Entra ID. In topics that require the user to interact with the Entra ID Admin site, we use the same names Microsoft does. However, there are still CData connection properties whose names or values reference "Azure AD".

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 Service Principal App in Entra ID (Azure AD).

Connection Properties

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

Managing Connections

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