Access Aha Data in Mule Applications Using the CData JDBC Driver

The CData API Driver for JDBC connects Aha data to Mule applications enabling read functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze Aha data.

This article demonstrates how to use the CData API Driver for JDBC inside of a Mule project to create a Web interface for Aha data. The application created allows you to request Aha data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the 200+ available data sources.

1. Create a new Mule Project in Anypoint Studio.
2. Add an HTTP Connector to the Message Flow.
3. Configure the address for the HTTP Connector.
4. Add a Database Select Connector to the same flow, after the HTTP Connector.
5. Create a new Connection (or edit an existing one) and configure the properties.
   • Set Connection to "Generic Connection"
   • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.api.jar).
   • Set the URL to the connection string for Aha

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

     Aha! API Profile Settings

     The Aha! API uses OAuth-based authentication.

     You will first need to register an OAuth app with Aha!. This can be done from your Aha! account under 'Settings' > 'Personal' > 'Developer' > 'OAuth Applications'. Additionally, you will need to set the Domain, found in the domain name of your Aha account. For example if your Aha account is acmeinc.aha.io, then the Domain should be 'acmeinc'.

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

     • AuthScheme: Set this to OAuth.
     • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
     • OAuthClientId: Set this to the client_id that is specified in you app settings.
     • OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
     • CallbackURL: Set this to the Redirect URI you specified in your app settings.
     • Domain: Set this in the ProfileSettings to your Aha domain.

     Built-in Connection String Designer

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

   • Set the Driver class name to cdata.jdbc.api.APIDriver.
   • Click Test Connection.
6. Set the SQL Query Text to a SQL query to request Aha data. For example: SELECT Id, Name FROM Ideas WHERE AssignedToUserId = 'my_user_id'
7. Add a Transform Message Component to the flow.
8. Set the Output script to the following to convert the payload to JSON:

   %dw 2.0
   output application/json
   ---
   payload
           

9. To view your Aha data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Aha data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with Aha data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for Aha and see the CData difference in your Mule Applications today.
