Connect to Greenhouse Data in HULFT Integrate

HULFT Integrate is a modern data integration platform that provides a drag-and-drop user interface to create cooperation flows, data conversion, and processing so that complex data connections are easier than ever to execute. When paired with the CData JDBC Driver for Greenhouse, HULFT Integrate can work with live Greenhouse data. This article explains how to connect to Greenhouse and move the data into a CSV file.

With built-in optimized data processing, the CData JDBC driver offers unmatched performance for interacting with live Greenhouse data. When you issue complex SQL queries to Greenhouse, the driver pushes supported SQL operations, like filters and aggregations, directly to Greenhouse and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Greenhouse data using native data types.

Enable Access to Greenhouse

To enable access to Greenhouse data from HULFT Integrate projects:

1. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.greenhouse.jar (and cdata.jdbc.greenhouse.lic), to the jdbc_adapter subfolder for the Integrate Server
2. Restart the HULFT Integrate Server and launch HULFT Integrate Studio

Build a Project with Access to Greenhouse Data

Once you copy the JAR files, you can create a project with access to Greenhouse data. Start by opening Integrate Studio and creating a new project.

1. Name the project
2. Ensure the "Create script" checkbox is checked
3. Click Next 👁 Creating a new project.
   
4. Name the script (e.g.: GreenhousetoCSV)

Once you create the project, add components to the script to copy Greenhouse data to a CSV file.

Configure an Execute Select SQL Component

Drag an "Execute Select SQL" component from the Tool Palette (Database -> JDBC) into the Script workspace.

1. In the "Required settings" tab for the Destination, click "Add" to create a new connection for Greenhouse. Set the following properties:
   • Name: Greenhouse Connection Settings
   • Driver class name: cdata.jdbc.greenhouse.GreenhouseDriver
   • URL: jdbc:greenhouse:APIKey=YourAPIKey;
     
     👁 JDBC connection settings (Salesforce is shown).
     

     Built-in Connection String Designer

     For assistance constructing the JDBC URL, use the connection string designer built into the Greenhouse JDBC Driver. Either double-click the JAR file or execute the JAR file from the command-line.

     		java -jar cdata.jdbc.greenhouse.jar
     		

     Fill in the connection properties and copy the connection string to the clipboard.

     You need an API key to connect to Greenhouse. To create an API key, follow the steps below:

     1. Click the Configure icon in the navigation bar and locate Dev Center on the left.
     2. Select API Credential Management.
     3. Click Create New API Key.
     • Set "API Type" to Harvest.
     • Set "Partner" to custom.
     • Optionally, provide a description.
     4. Proceed to Manage permissions and select the appropriate permissions based on the resources you want to access through the driver.
     5. Copy the created key and set APIKey to that value.

2. Write your SQL statement. For example:

   SELECT Id, CandidateId FROM Applications

3. Click "Extraction test" to ensure the connection and query are configured properly
4. Click "Execute SQL statement and set output schema"
5. Click "Finish" 👁 Configuring the Execute Select SQL operation
   

Configure a Write CSV File Component

Drag a "Write CSV File" component from the Tool Palette (File -> CSV) onto the workspace.

1. Set a file to write the query results to (e.g. Applications.csv)
2. Set "Input data" to the "Select SQL" component
3. Add columns for each field selected in the SQL query
4. In the "Write settings" tab, check the checkbox to "Insert column names into first row"
5. Click "Finish"

Map Greenhouse Fields to the CSV Columns

Map each column from the "Select" component to the corresponding column for the "CSV" component.

Finish the Script

Drag the "Start" component onto the "Select" component and the "CSV" component onto the "End" component. Build the script and run the script to move Greenhouse data into a CSV file.
