# n8n

ToolJet can trigger n8n workflows using webhook URLs. Please refer [this](https://docs.n8n.io/) to know more about n8n.

## 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](https://docs.tooljet.com/docs/data-sources/overview) page from the ToolJet dashboard.

n8n webhooks can be called with or without an **Authentication**. You can keep the `Authentication type` as `none` if your webhook didn't have one or if it has one then you can choose the one from the dropdown and provide credentials:

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