 This example demonstrates how to define a connector setup form using `ConfigurationForm`, `form_field`, and `Test` from the Fivetran Connector SDK. It covers plain text, password, dropdown, and toggle fields, including dropdown options with labels and descriptions. It also shows how to register a connection test that Fivetran runs when the user clicks **Test Connection** during setup.
 
-The API fields (`api_base_url`, `api_key`) in the configuration form illustrate how a real connector would collect connection details. The `configuration.json` file provided contains sample values for running the connector locally.

+> Note: This project includes an empty `configuration.json` because it is required during deployment. You can optionally populate it and then deploy with the pre-populated file so the values appear pre-filled in the [setup form](https://fivetran.com/docs/connector-sdk/technical-reference/connector-sdk-setup-form). 
 
 Refer to `def configuration_form()` and `def connection_test()` in `connector.py` for the main setup form and test implementation.
