Connect to Harvest Data in Aqua Data Studio

The CData JDBC Driver for Harvest integrates Harvest data with wizards and analytics in IDEs like Aqua Data Studio. This article shows how to connect to Harvest data through the connection manager and execute queries.

Create a JDBC Data Source

You can use the connection manager to define connection properties and save them in a new JDBC data source. The Harvest data source can then be accessed from Aqua Data Studio tools.

1. In Aqua Data Studio, select Register Server from the Servers menu.
2. In the Register Server form, select the 'Generic - JDBC' connection.
3. Enter the following JDBC connection properties:
   • Name: Enter a name for the data source; for example, Harvest.
   • Driver Location: Click the Browse button and select the cdata.jdbc.api.jar file, located in the lib subfolder of the installation directory.
   • Driver: Enter the Driver's class name, cdata.jdbc.api.APIDriver.

   • URL: Enter the JDBC URL, which starts with jdbc:api: and is followed by a semicolon-separated list of connection properties.

     Start by setting the Profile connection property to the location of the Harvest Profile on disk (e.g. C:\profiles\Harvest.apip). Next, set the ProfileSettings connection property to the connection string for Harvest (see below).

     Harvest API Profile Settings

     To authenticate to Harvest, you can use either Token authentication or the OAuth standard. Use Basic authentication to connect to your own data. Use OAuth to allow other users to connect to their data.

     Using Token Authentication

     To use Token Authentication, set the APIKey to your Harvest Personal Access Token in the ProfileSettings connection property. In addition to APIKey, set your AccountId in ProfileSettings to connect.

     Using OAuth Authentication

     First, register an OAuth2 application with Harvest. The application can be created from the "Developers" section of Harvest ID.

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

     • ProfileSettings: Set your AccountId in ProfileSettings.
     • AuthScheme: Set this to OAuth.
     • OAuthClientId: Set this to the client ID that you specified in your app settings.
     • OAuthClientSecret: Set this to the client secret that you specified in your app settings.
     • CallbackURL: Set this to the Redirect URI that you specified in your app settings.
     • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage how the driver obtains and refreshes the OAuthAccessToken.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Harvest 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.

     A typical JDBC URL is below:
     jdbc:api:Profile=C:\profiles\Harvest.apip;ProfileSettings='APIKey=my_personal_key;AccountId=_your_account_id';

Query Harvest Data

You can now query the tables exposed.
