### Authentication

To authenticate Imperva connector, an API Key is required. To obtain this key, log in to your Imperva account and navigate to **Account** > **My Profile** > **API Keys**. Click on "Add API Key" to generate a new key. Enter a name (and optionally otherparameters) for the API Key and click on "Create".
