This string includes the properties used to connect with URL parameter (API key) authentication.

jdbc:datadirect:aha:servername;AuthenticationMethod=UrlParameter;SecurityToken=security_token;
[property=value[;...]];

where:

servername
specifies the base URL of the Aha! service to which you want to issue requests. For example, company.aha.io.
security_token
specifies the API key required to make a connection to your endpoint. API keys can be generated through the Aha! user interface. Refer to the Aha! documentation for more information.
property=value
specifies connection property settings. Multiple properties are separated by a semi-colon.

The following example connection string demonstrates the properties required for connecting with URL parameter authentication.

Connection conn = DriverManager.getConnection
  ("jdbc:datadirect:aha://company.aha.io;authenticationMethod=UrlParameter;
    securitytoken=1234abc5d6789efg;");
