Build Bullhorn CRM-Connected Apps in Mendix

Mendix is a high-productivity app platform that allows you to build and maintain both mobile and web applications at-scale. When paired with CData Connect Cloud, Mendix provides instant, cloud-to-cloud access to Bullhorn CRM data for applications. This article demonstrates how to connect to a CData Connect Cloud data source from within Mendix.

CData Connect Cloud provides a pure cloud-to-cloud interface for Bullhorn CRM, allowing you to import data from live Bullhorn CRM data in Mendix — without replicating the data to a natively supported database. As you build web and mobile applications from within Mendix, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Bullhorn CRM, leveraging server-side processing to return the requested Bullhorn CRM data quickly.

Configure Bullhorn CRM Connectivity for Mendix

Connectivity to Bullhorn CRM from Mendix is made possible through CData Connect Cloud. To work with Bullhorn CRM data from Mendix, we start by creating and configuring a Bullhorn CRM connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Bullhorn CRM" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Bullhorn CRM.

   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.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Bullhorn CRM Connection page and update the User-based permissions.
