## Connection

To establish a connection with the n8n data source, click on the **+ Add new Data source** button located on the query panel or navigate to the [Data Sources](/docs/data-sources/overview) page from the ToolJet dashboard.

Webhooks in n8n can be configured to operate with or without **Authentication**. If no authentication is required, select `None` as the **Authentication type**. For webhooks that require authentication, choose the appropriate method from the dropdown and provide the corresponding credentials.

### Authentication Types
- **Basic Auth**: To connect your n8n webhooks using basic auth you'll need to provide the following credentials:
    - **Username**
    - **Password**
