How to use the intent inform in Rasa?

Question

I am trying to create a chatbot for banking. Flow is,

User: hi 
Bot: Welcome to ABC bank services. Let me know your name?
User: Kabeer 
Bot: Hi kabeer, how can i help you?
 Buttons:
 1: Loan (/inform{“service_type”:“Loan”})
 2: Deposit (/inform{“service_type”:“Deposit”})
 3: Account Types (/inform{“service_type”:“Account Types”})
 4: Customer Support No (/inform{“service_type”:“Customer Support No”})
 5: Service Request (/inform{“service_type”:“Service Request”})
 6: Careers (/inform{“service_type”:“Careers”})
Type out your own message…
User: 1: Loan (/inform{“service_type”:“Loan”})
Bot:Please select the required Loan type from the list
  Buttons:
1: Personal Loan (/inform{“loan_type”:“Personal Loan”})
2: Home Loan (/inform{“loan_type”:“Home Loan”})
3: Two-wheeler Loan (/inform{“loan_type”:“Two-wheeler Loan”})
4: Car Loan (/inform{“loan_type”:“Car Loan”})
5: Gold Loan (/inform{“loan_type”:“Gold Loan”})
Type out your own message…
User:Car Loan (/inform{“loan_type”:“Car Loan”})
 Bot: Uttering home loan here. 

Issue is the bot always utter home loan only. The bot is not recognise the stories for other loans using entity. How can i make this work? I used inform intent because of i thought it will cause similar intnent problem

Answer 1

slots of type text are featurized in a way that it only affects the story flow if they are set or not (docs for it here) I think in your case you rather want to use a categorical slot. In this case the stories will go down different paths depending on the slot value (docs for it here)
