Watson conversation - context - previous input tex

Question

During a conversation sequence, when an user provides an input for a response coming from the conversation service based on his/her previous question, I am building a new request to the conversation service by passing the previous question as input text and the previous context.

The previous context is to let the Conversation service know the conversation id. The previous input text (question) is to let the Conversation service identify and resume from where it was left (the right dialog node).

My application uses the user input for validation and updating the context. For instance, setting the context as user "verified" etc.

My application gets the previous input text from the context object of conversation service.

Could you please let me know if i am doing right?
