Hey @lohith.arcot. I think this is the best use case for the Rasa forms - you can define which slots are required and must be filled before an assistant can run a specific action. Until all required slots are populated, an assistant will ask the user for those details. We actually wrote a tutorial on Rasa forms, I hope it helps: [Building contextual assistants with Rasa Forms](https://blog.rasa.com/building-contextual-assistants-with-rasa-formaction/)
