Hi Isura, Thanks for your response. Let me explain bit more about what I need to accomplish. What my task need to do is retrieve some information from third party Rest API and publish those data to a BAM instance. Would it be able to do this without implementing custom classes? As you said I have to create task configuration for each and every task I create. My question is can I load those task configurations from a xml file or something rather than manually adding task configurations for each and every task I implement? I mean like what would be the correct way to configure those task configurations in a production environment?
