How to build a simple VCL Application to view ServiceDesk Plus data in RAD Studio using the CData ODBC Driver for ServiceDesk Plus.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for ServiceDesk Plus, you gain access to live ServiceDesk Plus data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve ServiceDesk Plus data. This article will walk through connecting to ServiceDesk Plus and creating a simple VCL application with the Form Designer.

Create a Connection to ServiceDesk Plus Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Using OAuth Authentication

ServiceDeskPlus uses Zoho OAuth 2.0 for secure authentication. To set up OAuth access:

  1. Register your application in the Zoho Developer Console at https://api-console.zoho.com
  2. Configure your redirect URI to match your application setup
  3. Note your Client ID and Client Secret from the application settings

After setting the following connection properties, you are ready to connect:

  • AuthScheme: Set this to OAuth.
  • OAuthClientId: Set this to your Zoho application Client ID.
  • OAuthClientSecret: Set this to your Zoho application Client Secret.
  • Scope: Set this to the required ServiceDeskPlus permissions (default includes read access to requests, problems, assets, and projects).
  • Domain: Set this to your ServiceDeskPlus domain
  • Portal: Set this to your ServiceDeskPlus portal

Example Connection String

Profile=C:\profiles\ServiceDeskPlus.apip;ProfileSettings="Portal=itdesk;Domain=.in;Scope=SDPOnDemand.requests.READ SDPOnDemand.problems.READ SDPOnDemand.assets.READ SDPOnDemand.projects.READ";AuthScheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to ServiceDesk Plus data.

  1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
  2. Right-click the ODBC Data Source node in the Data Explorer.
  3. Click Add New Connection.
  4. Enter a name for the connection.
  5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for ServiceDesk Plus.

Create VCL Applications with Connectivity to ServiceDesk Plus Data

Follow the procedure below to start executing queries to ServiceDesk Plus data from a simple VCL application that displays the results of a query in a grid.

  1. Drop a TFDConnection component onto the form and set the following properties:

    • ConnectionDefName: Select the FireDAC connection to ServiceDesk Plus data.
    • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
  2. Drop a TFDQuery component onto the form and set the properties below:

    • Connection: Set this property to the TFDConnection component, if this component is not already specified.
    • SQL: Click the button in the SQL property and enter a query. For example:

      SELECT ,  FROM AnnouncementComments WHERE AnnouncementId = '12345'
      
    • Active: Set this property to true.
  3. Drop a TDataSource component onto the form and set the following property:

    • DataSet: In the menu for this property, select the name of the TFDQuery component.
  4. Drop a TDBGrid control onto the form and set the following property:

    • DataSource: Select the name of the TDataSource.
  5. Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
