Use the CData Connector for Bullhorn CRM in APOS Live Data Gateway to build Semantic Layer Views for Bullhorn CRM data.
APOS Live Data Gateway (LDG) is a data connection and data transformation solution that enables live data connectivity and expanded data source options for SAP Analytics Cloud and other SAP solutions. When paired with CData Connectors, users can build semantic layer views for live Bullhorn CRM data, enabling real-time analytics on Bullhorn CRM just like working with a relational database.
With built-in optimized data processing, the CData Connector offers unmatched performance for interacting with live Bullhorn CRM data. When you issue complex SQL queries to Bullhorn CRM, the driver pushes supported SQL operations, like filters and aggregations, directly to Bullhorn CRM 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 Bullhorn CRM data using native data types.
Download and Install the Connector Files
In order to access Bullhorn CRM data through the APOS Live Data Gateway, you will need to download the connector files from APOS and install them on the machine hosting the Live Data Gateway. An APOS representative can deliver the necessary files.
- Install the CData DLL file (System.Data.CData.BullhornCRM.dll) to the APOS Live Data Gateway installation directory (C:\Program Files\Live Data Gateway\Admin\ by default).
- Install the CData JAR file (cdata.jdbc.bullhorncrm.jar) to the ConnectionTest_lib folder in the installation directory (C:\Program Files\Live Data Gateway\Admin\ConnectionTest_lib\ by default).
- Install the CData JAR file (cdata.jdbc.bullhorncrm.jar) to the lib folder in the Web UI installation directory (e.g.: C:\LDG_WebUI\lib\)
Configuring the Bullhorn CRM Connection String
Before establishing the connection to Bullhorn CRM from the APOS Live Data Gateway, you need to configure the Bullhorn CRM JDBC Connection String.
Built-in Connection String Designer
For assistance in constructing the JDBC Connection String, use the connection string designer built into the Bullhorn CRM JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.bullhorncrm.jar
Fill in the connection properties and copy the connection string to the clipboard.
Begin by providing your Bullhorn CRM account credentials in the following:
- DataCenterCode: Set this to the data center code which responds to your data center. Refer to the list of data-center-specific Bullhorn API URLs: https://bullhorn.github.io/Data-Center-URLs/
If you are uncertain about your data center code, codes like CLS2, CLS21, etc. are cluster IDs that are contained in a user's browser URL (address bar) once they are logged in.
Example: https://cls21.bullhornstaffing.com/BullhornSTAFFING/MainFrame.jsp?#no-ba... indicates that the logged in user is on CLS21.
Authenticating with OAuth
Bullhorn CRM uses the OAuth 2.0 authentication standard. To authenticate using OAuth, create and configure a custom OAuth app. See the Help documentation for more information.

Your connection string will look similar to the following:
jdbc:BullhornCRM:DataCenterCode=CLS33;OAuthClientId=myoauthclientid;OAuthClientSecret=myoauthclientsecret;
Connecting to Bullhorn CRM & Creating a Semantic Layer View
After installing the connector files and configuring the connection string, you are ready to connect to Bullhorn CRM in the Live Data Gateway Admin tool and build a semantic layer view in the Live Data Gateway Web UI.
Configuring the Connection to Bullhorn CRM
- Log into your APOS Live Data Gateway Manager
- If you haven't already, update your APOS LDG license file
- Click File -> Configurations
- Click on the "..." Menu for the License
- Select the license file from the APOS team that includes your CData Connector license
- In the APOS Live Data Gateway Manager, click "Add"
- In the APOS Live Data Gateway On the Connection tab, configure the connection:
- Set Data Source to "Database"
- Set Database to "CData Drivers"
- Set Database CData Drivers to "Bullhorn CRM"
- Set Connection String to the connection string configured earlier (e.g.:
jdbc:BullhornCRM:DataCenterCode=CLS33;OAuthClientId=myoauthclientid;OAuthClientSecret=myoauthclientsecret;
- Set Driver Class to "cdata.jdbc.bullhorncrm.BullhornCRMDriver" (this should be set by default)
- Click Test Connection
- Click Save
- Give your connection a unique prefix (e.g. "bullhorncrm")
- Highlight the newly created connection and click File -> "Approve Users For Web UI"
- Approve the appropriate DB users to create views and click "Save"
At this point, we are ready to build our semantic layer view in the Live Data Gateway Web UI.
Creating a Semantic Layer View
- In your browser, navigate to the APOS Live Data Gateway Portal
- Select a Connection (e.g. "bullhorncrm")
- Since Bullhorn CRM does not require a User or Password to authenticate, you may use whatever values you wish for User Name and Password
- Click "Login"
- Once connected, click "Semantic Layer" to create a new semantic layer view
- Click "New Semantic Layer View"
- Set the Semantic Layer View Prefix and Semantic Layer View Name
- Click "Step 2"
- Select the table(s) and column(s) you wish to include in your view
- Click "Step 3"
- Select the Measures from the available table columns
- Click "Step 5" (we skipped the "Extra Dimensions" step)
- Add any Variable Prompts
- Click "Step 6"
- Define any Table Joins
- Click "Review"
- Review you semantic layer view and click "Save"
With the Semantic Layer View created, you are ready to access your Bullhorn CRM data through the APOS Live Data Gateway, enabling real-time data connectivity to Bullhorn CRM data from SAP Analytics Cloud and other SAP solutions.
