Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

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 application (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.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Ensuring Registry Access

The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:

1. Run the calling application as an administrator.
2. Connect via a User DSN instead of a System DSN.

Connecting to Avalara

By default, the driver connects to a production environment. Set UseSandbox to true to configure the driver to connect to a Avalara sandbox environment.

Authenticating to Avalara

There are two authentication methods available for connecting to the Avalara data source: Basic and LicenseKey.

Login Credentials

To use login credentials for authentication, set the following:

• AuthScheme: Set this to Basic.
• User: Set this to your Avalara username.
• Password: Set this to your Avalara password.

Account Number and License Key

Alternatively, you can authenticate using your account number and license key. Connect to the data source using the following:

• AuthScheme: Set this to LicenseKey.
• AccountId: Set this to your Avalara Account Id. The Account Id is listed in the upper right-hand corner of the Avalara admin console.
• LicenseKey: Set this to your Avalara license key. You can generate a license key by logging into Avalara as an account adminstrator and navigating to Settings > Reset License Key.
