Hi , I have a Intent “leave_balance” , withen which i have different types of leave like paid leave , sick leave etc , hence I have created a entity “leave_type” type : list . the Nlu is able to categorize different types of leaves . Not When the slot is set to sick leave i want to get only the sick leave balance from web service . please check my actions.py file below

class GetLeaveBalance(Action):

def name(self):
    return 'get_leave_balance'




def run(self, dispatcher, tracker, domain):
    
    
    #importing librires to connect with wsdl 
    from suds.client import Client
    from suds.sax.element import Element
    
    #specfying the wsdl url and setting the client 
    url = "http://devmobileapi.xxxxxxxxxxxxxxxxxxxx.in/API/xxxxxxxxxxxxxxxx.svc?wsdl"
    client = Client(url)
    
    #creating the headers for auth in service xml and setting the values for both API-key and API-Code
    Namespace = ('ns2', 'http://xxxxxxxxxxxxxxxxxxxxxx.com/v1')
    name_space = Element('APICode', ns=Namespace).setText('xxxxxxxxxxxxxxxxxxx')

    Apikey =('ns2',"http://beehivehronline.com/v1")
    api_key = Element('APIKey',ns= Apikey).setText('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx')
    
    client.set_options(soapheaders=(name_space,api_key))
    
    # getting the leave data from GetLeaveBalance for specific user 
    leave=client.service.GetLeaveBalance('1')
    leave_data= Client.dict(leave)

##################### Creating list of leave types

    leave_type=["short_leave", "casual_leave", "sick_leave","earned_leave", "leave_without_pay",
                "paid_leave","paternity_leave","leave"]
    
    # saving the leave type
    leave_t= tracker.get_slot("leave_type")
    #leave_t=latest_message.get("leave_type")
    
    # specifing conditions for different leave types
    if leave_t =="leave":
        
        
        short_l=leave_data['LeaveBalance']["LeaveBalanceData"][0]["Balance"]
        casual_l=leave_data['LeaveBalance']["LeaveBalanceData"][1]["Balance"]
        sick_l=leave_data['LeaveBalance']["LeaveBalanceData"][2]["Balance"]
        earned_l=leave_data['LeaveBalance']["LeaveBalanceData"][3]["Balance"]
        without_pay_l=leave_data['LeaveBalance']["LeaveBalanceData"][4]["Balance"]
        privilege_l=leave_data['LeaveBalance']["LeaveBalanceData"][5]["Balance"]
        Paternity_l=leave_data['LeaveBalance']["LeaveBalanceData"][6]["Balance"]
        
        
        text_leave=(""" Your Leave balance summary is as follows:
                Short Leave :{}

    dispatcher.utter_message(text_leave)

    return []

Domain file

I did manage to solve this

To use list slot , you need to make minor change

# saving the leave type
   leave_list= tracker.get_slot("leave_type")
   leave_t = leave_list[0]

Thank you Aashay
