## Configuration
ToolJet's Databricks integration relies on a configuration form that supports the following parameters:
#### Required Parameters
- **Server hostname**: The server hostname or the IP address of your Databricks Warehouse. For example, `62596234423488486.6.gcp.databricks.com`.
- **HTTP Path**: The API endpoint path for the Databricks resource you want to access. For example, `/sql/1.0/warehouses/44899g7346c19m95`.
- **Personal access token**: Personal access tokens are used for secure authentication to the Databricks API instead of passwords. For example, `dapi783c7d155d138d8cf14`.
#### Optional Parameters
- **Port**: The port number of your Databricks Warehouse. The default port number is `443`.
- **Default Catalog**: The default catalog to use for the connection.
- **Default Schema**: The default schema to use for the connection.
### Setup
- Navigate to your Databricks workspace, select the desired SQL Warehouse, and find **Server Hostname** and **HTTP Path** within the connection details tab.
- To generate a personal access token, access your Databricks User Settings, select the Developer tab, click Manage under Access Tokens, and then click on the **Generate New Token** button.
- Navigate to the Databricks datasource configuration form in ToolJet, fill in the required parameters, and click the **Save** button. You can test the connection by clicking the **Test Connection** button.
