Here you can get some guidance:

• Copy 'adaptivepayments-java-sdk.jar' to your class path.
• Copy the configuration file 'sdk_config.properties' in SDK 'resource' folder to your project.
• Import AdaptivePaymentsService into your code.

• Load the configuration file into your application with this method call as required:

  new AdaptivePaymentsService(new File(".../sdk_config.properties")); 
  

• Create a service wrapper object.
• Create a request object as per your project needs.
• Invoke the appropriate method on the service wrapper object.
