This string includes the properties you may need to connect through a proxy server with basic authentication.

jdbc:datadirect:aha:servername;ProxyHost=proxy_host;ProxyPassword=proxy_password;
ProxyPort=proxy_port;ProxyUser=proxy_user;AuthenticationMethod=method;
user=username;password=password;[property=value[;...]];

where:

servername
specifies the base URL of the Aha! service to which you want to issue requests. For example, company.aha.io.
proxy_host
specifies the proxy server to use for the first connection.
proxy_password
specifies the password needed to connect to a proxy server for the first connection.
proxy_port
specifies the port number where the proxy server is listening for requests for the first connection. The default is 0, which means the port number is determined by the setting of the ProxyHost property. If an http URL is specified, the default port number is 80. If an https URL is specified, the default is 443.
proxy_user
specifies the user name needed to connect to a proxy server for the first connection.
user
specifies the user name that is used to connect to the Aha! service. For example, jsmith@company.com.
password
specifies the password used to connect to your Aha! service.
property=value
specifies connection property settings. Multiple properties are separated by a semi-colon.
Note: The User and Password properties are not required to be stored in the connection string. They can also be passed separately by the application.

The following example connection string includes the properties required for using a proxy server with OAuth 2.0 refresh token grant authentication.

Connection conn = DriverManager.getConnection
  ("jdbc:datadirect:aha:company.aha.io;ProxyHost=pserver;ProxyPassword=secret;
    ProxyPort=808;ProxyUser=jsmith;user=jsmith@company.com;password=secret;");
