Connect to Trello Data and Transfer Data in Talend

This article shows how you can easily integrate the CData JDBC driver for Trello into your workflow in Talend. This article uses the CData JDBC Driver for Trello to transfer Trello data in a job flow in Talend.

Connect to Trello in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Trello:

1. Add a new database connection to Trello data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
2. In the resulting wizard, enter a name for the connection.

3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

   Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

   Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

   • Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
   • OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.trello.jar

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

   A typical JDBC URL is below:

   jdbc:trello:APIKey=myApiKey;Token=myGeneratedToken;InitiateOAuth=GETANDREFRESH
4. Enter the path to the cdata.jdbc.trello.jar file, located in the lib subfolder of the installation directory.
5. Right-click the connection and then click Retrieve Schema.
6. Click Next with the default options to select the tables you want to import.
7. Finish the wizard with the default options.

Output the Boards Table to a Flat File

You can follow the procedure below to transfer the Boards table to a flat file output component:

1. In the Table Schemas node, drag the tables to the workspace.
2. In the dialog that is displayed, select the tJDBCInput component.
3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
4. Right-click the Boards tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
