CData Power BI Connector for Google BigQuery 2019 - Build 19.0.7354

This section describes how to edit the DSN configuration and then authenticate and connect to Google BigQuery APIs.

Editing the DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process, as described in Installing the Connector.

Complete the following steps to edit the DSN configuration:

  1. Select Start > Search, and enter ODBC Data Sources in the Search box.
  2. Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
  3. Click the System DSN tab.
  4. Select the system data source and click Configure.
  5. Edit the information on the Connection tab and click OK.

Authenticate via OAuth Authentication

Use the OAuth authentication standard to connect to Google BigQuery. You can authenticate with a user account or with a service account. A service account is required to grant organization-wide access scopes to the connector. The connector facilitates these authentication flows as described below.

Authenticate with a User Account

You can connect without setting any connection properties for your user credentials. After setting the following, you are ready to connect:

  • DatasetId: Set this to the Id of the dataset you want to connect to.
  • ProjectId: Set this to the Id of the project you want to connect to.
When you connect the connector opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process.

See Using OAuth Authentication for other OAuth authentication flows.

Authenticate with a Service Account

Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the connector.

You need to create an OAuth application in this flow. See Creating a Custom OAuth App in the Getting Started section to create and authorize an app. You can then connect to Google BigQuery data that the service account has permission to access.

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

  • OAuthJWTCertType: Set this to "PFXFILE".
  • OAuthJWTCert: Set this to the path to the .p12 file you generated.
  • OAuthJWTCertPassword: Set this to the password of the .p12 file.
  • OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
  • OAuthJWTSubject: Set this to the email address of the user for whom the application is requesting delegate access. Note that delegate access must be granted by an administrator.
  • OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
  • DatasetId: Set this to the Id of the dataset you want to connect to.
  • ProjectId: Set this to the Id of the project you want to connect to.
When you connect the connector completes the OAuth flow for a service account.

Next Step

See Getting Data for the next step, which is connecting to the data that you want to work with.
