Connect to Customer.io Data in JRuby

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Customer.io makes it easy to integrate connectivity to live Customer.io data in JRuby. This article shows how to create a simple JRuby app that connects to Customer.io data, executes a query, and displays the results.

Configure a JDBC Connection to Customer.io Data

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Customer.io\lib).

JRuby natively supports JDBC, so you can easily connect to Customer.io and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

Using API Key Authentication

To obtain your Customer.io App API Key, navigate to the Customer.io UI under Data & Integrations > Integrations > Customer.io API and generate your API key.

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

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Customer.io App API Key.

Example Connection String

Profile=C:\profiles\CustomerIO.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";

Built-in Connection String Designer

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

java -jar cdata.jdbc.api.jar

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

Below is a typical JDBC connection string for Customer.io:

jdbc:api:Profile=C:\profiles\CustomerIO.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";

Create a JRuby App with Connectivity to Customer.io Data

Create a new Ruby file (for example: APISelect.rb) and open it in a text editor. Copy the following code into your file:

require 'java'
require 'rubygems'
require 'C:/Program Files/CData/CData JDBC Driver for Customer.io 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\CustomerIO.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT ,  FROM Customers")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

With the file completed, you are ready to display your Customer.io data with JRuby. To do so, simply run your file from the command line:

jruby -S APISelect.rb
