Hello, How do I fill the slots using custom actions? For example: I have a form where I have defined the slots in function such as: @staticmethod def required_slots(tracker: Tracker) -> List[Text]: return ["name","cuisine","time"] I want to define the utter_ask_cuisine as a custom action because the value will be shown as a button and be fetched from the backend (which is dynamic in nature). class ActionCuisine(Action): def name(self) -> Text: return "utter_ask_cuisine" def run(self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]) -> List[Dict[Text, Any]]: cuisine_data = grabCuisine() buttons = [] for data in cuisine_data: buttons.append({"title": data, "payload": "/cuisine"}) slot_name = tracker.get_slot('name') dispatcher.utter_message( text="Please choose your liking", buttons=buttons) return [] Is it possible to fill the slot value by calling a custom action that fetches the values from the backend? If I am defining the utter_ask_cusine template as part of the response in the domain.yml file, it wont be dynamic but will have fixed button values. I am getting the following error: UserWarning: Utterance ‘utter_ask_cuisine’ is listed as an action in the domain file, but there is no matching utterance template. Any reference would be really helpful :slight_smile: Thanks.

Hey @_adityaK you can just add the following code to your return[] return [SlotSet('slot_name', 'slot_value')] Hope it helps :slightly_smiling_face:

Hey @jusce17 , thanks for your reply. :slight_smile: But I will take a step back. To set the slot_value for cuisine, I need the input from the user. How can I call the ActionCuisine when the bot comes to the slot cuisine in the function required_slots. Can we define utter_ask_cusine as a custom action the way I have done it above? Apologies if I am not clear with my question :frowning:

I was able to achieve this by using request_next_slot(). Thanks @jusce17 for your input. It was helpful
