Build a Simple VCL Application for Reply.io Data

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

Create a Connection to Reply.io 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.

The Reply.io API uses API Key authentication via the x-api-key request header.

Using API Key Authentication

Your Reply.io API key is required to create a connection. To obtain your API key:

1. Log into your Reply.io account.
2. Click your profile icon and select Settings.
3. Navigate to the API section.
4. Copy your API Key.

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Reply.io API key.
• UserEmail (optional): Set this to the email address of the Reply.io user on whose behalf requests are made.

Example connection string:

Profile=C:\profiles\ReplyIO.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Reply.io 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 Reply.io.

Create VCL Applications with Connectivity to Reply.io Data

Follow the procedure below to start executing queries to Reply.io 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 Reply.io 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 BillingInfo WHERE  = ''
     

   • 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.
