Chatbot RequirementsRealtime InfrastructureSome level of Artificial IntelligenceDomain specific knowledge
But remember...Requirements, not focus
So... Don’t build your own Realtime InfrastructureDon’t build your own Artificial Intelligence

Conversation Service
Create Intents
Create Entities
Create Dialogs
Process Dialogvar url = creds.url+'/v1/workspaces/'+creds.workspaceID+'/message?version=2016-09-20';
