Step 1: The user sends a message to the chatbot through one of the available clients. They can be the web chat or the sd chat generated.

Step 2: The Server (where the programs generated by the Chatbot generator run) receives the message and sends it to the AI provider with whom you're working (i.e: Watson)

Step 3: The AI provider applies its NLP algorithms on the model generated with the Conversational Flows, in order to define what the user wants. Respond to the server with the intention and parameters detected. 

Step 4: The server responds to the response of the NLP Provider, and based on the action that was understood that the user wants to perform, is redirected internally to the service generated to comply with it. These "generated services" know how to communicate with the objects that the user defined as resolvers for a flow (the Conversational objects).
When do they communicate with the "resolve"?
This is decided by the provider, that is, if, when processing the message and validating the state of the context, it is understood that the flow is ready to execute an action, the conversational object is called to do what it has to do.
When are you ready to execute an action?
Canonical case: When the user answered all the parameters of the flow. -> It can vary depending on the state of those parameters in the context, or of the conditions / redirections.

Step 5: The user is answered. This response can have different formats, depending on what has been defined in the Conversational Flows for the flow in question.
