Connection Configuration

Once your driver is installed and licensed, you're ready to configure a connection to HubDB. The CData Power BI Connector for HubDB is built on top of an ODBC driver, so it uses a DSN (Data Source Name) to store connection properties.

Creating a DSN

Windows: Using ODBC Data Source Administrator

1. Open the ODBC Data Source Administrator (64-bit)

   Note: CData Power BI connectors use the 64-bit version.

   • Search for "ODBC" in the Windows Start menu
   • Or navigate to: Control Panel -> Administrative Tools -> ODBC Data Sources
2. Click the System DSN or User DSN tab
   • System DSN: Available to all users on the machine (recommended for services)
   • User DSN: Available only to the current user
3. Select CData PBI HubDB Source or Sys from the list (depending on User DSN or System DSN) or click Add to create a new data source.
4. Click Finish to open the connection configuration dialog.

Configuring Connection Properties

There are two authentication methods available for connecting to HubDB data source: OAuth Authentication with a public HubSpot application and authentication with a Private application token.

Using a Custom OAuth App

AuthScheme must be set to "OAuth" in all OAuth flows. Be sure to review the Help documentation for the required connection properties for you specific authentication needs (desktop applications, web applications, and headless machines).

Follow the steps below to register an application and obtain the OAuth client credentials:

1. Log into your HubSpot app developer account.
   • Note that it must be an app developer account. Standard HubSpot accounts cannot create public apps.
2. On the developer account home page, click the Apps tab.
3. Click Create app.
4. On the App info tab, enter and optionally modify values that are displayed to users when they connect. These values include the public application name, application logo, and a description of the application.
5. On the Auth tab, supply a callback URL in the "Redirect URLs" box.
   • If you're creating a desktop application, set this to a locally accessible URL like http://localhost:33333.
   • If you are creating a Web application, set this to a trusted URL where you want users to be redirected to when they authorize your application.
6. Click Create App. HubSpot then generates the application, along with its associated credentials.
7. On the Auth tab, note the Client ID and Client secret. You will use these later to configure the driver.

8. Under Scopes, select any scopes you need for your application's intended functionality.

   A minimum of the following scopes is required to access tables:

   • hubdb
   • oauth
   • crm.objects.owners.read
9. Click Save changes.
10. Install the application into a production portal with access to the features that are required by the integration.
    • Under "Install URL (OAuth)", click Copy full URL to copy the installation URL for your application.
    • Navigate to the copied link in your browser. Select a standard account in which to install the application.
    • Click Connect app. You can close the resulting tab.

Using a Private App

To connect using a HubSpot private application token, set the AuthScheme property to "PrivateApp."

You can generate a private application token by following the steps below:

1. In your HubDB account, click the settings icon (the gear) in the main navigation bar.
2. In the left sidebar menu, navigate to Integrations > Private Apps.
3. Click Create private app.
4. On the Basic Info tab, configure the details of your application (name, logo, and description).
5. On the Scopes tab, select Read or Write for each scope you want your private application to be able to access.
6. A minimum of hubdb and crm.objects.owners.read is required to access tables.
7. After you are done configuring your application, click Create app in the top right.
8. Review the info about your application's access token, click Continue creating, and then Show token.
9. Click Copy to copy the private application token.

To connect, set PrivateAppToken to the private application token you retrieved.

👁 Configure the HubDB DSN.

What's Next

Now that you have installed, licensed, and configured the driver, here are some scenarios you can use to explore our Power BI Connectors:

---

Installation & Licensing

Do I need administrator rights to install the connector?

Yes. Administrator rights are required to install the CData Power BI Connector because the installer writes to system directories and registers required components.

Is the connector available in 32-bit and 64-bit versions?

No. Power BI Desktop is 64-bit only, and all CData Power BI Connectors are distributed as 64-bit only MSI installers.

Connecting

What's the difference between System DSN and User DSN?

System DSNs are available to all users on a machine and are required when using the Power BI On-premises Data Gateway. User DSNs are only available to the Windows user who created them and are suitable for local Power BI Desktop use.

Can I use a DSN-less connection string instead of creating a DSN?

Yes. The underlying ODBC driver supports DSN-less connection strings, and Power BI can use DSN-less configuration when connecting through the ODBC connector.

Example:

Driver={CData Power BI Connector for HubDB};User=Value1;Password=Value2;SecurityToken=Value3;

(Exact properties depend on your HubDB authentication method.)

How do I connect to multiple HubDB accounts?

Create separate DSNs, one for each HubDB account, or create separate connection entries inside Power BI using different authentication credentials. Each DSN or connection stores its own settings.

Can I connect through a proxy server?

Yes. Proxy settings can be configured in the connection properties of your DSN or through the connector's Advanced Settings in Power BI.

Refer to the Firewall & Proxy section of the documentation for required properties and supported proxy scenarios.

---

Performance & Troubleshooting

Why are my queries slow?

Check the following:

• Use Import mode if you are working with large datasets or performing heavy transformations. Import mode caches data locally and reduces the number of live API calls.
• Use DirectQuery only when required, as it sends every query to HubDB in real time.
• Apply filters in Power Query to reduce the size of the dataset before loading.
• Avoid selecting all columns if only a subset is needed.
• Monitor HubDB API limits, which can throttle performance.
• Contact [email protected] for help with query optimization and best practices.

How do I enable logging for troubleshooting?

Logging can be enabled through the connector's advanced connection properties in Power BI Desktop.

In the connection dialog:

• Expand Advanced Options
• Set:
  • Logfile = path to a writable log file
  • Verbosity = 3 (or higher for detailed logs)

Be prepared to upload the log file when contacting [email protected] for analysis securely.

What ports does the connector need access to?

Most HubDB connections require outbound HTTPS (port 443) access. Ensure your firewall allows outbound secure traffic to HubDB endpoints.

For environments using proxies or additional security layers, consult the Firewall & Proxy section of the connector documentation.

Can I use the connector in a Linux container or Docker?

No. The CData Power BI Connector cannot be used in Linux containers because:

• Power BI Desktop runs only on Windows
• Power BI Gateway runs only on Windows
• Custom connector .pqx files are supported only on Windows

The Power BI Connector is a Windows-only component.
