Actions

from rasa_sdk import Action
from rasa_sdk.executor import CollectingDispatcher

class TrackPackageAction(Action):
    def name(self):
        return "track_package"

    def run(self, dispatcher, tracker, domain):
        package_id = tracker.get_slot("package_id")
        # Call Royal Mail API to track package
        #...
        dispatcher.utter_message(text=f"Package {package_id} is on its way!")

class FindPostOfficeAction(Action):
    def name(self):
        return "find_post_office"

    def run(self, dispatcher, tracker, domain):
        post_code = tracker.get_slot("post_code")
        # Call Royal Mail API to find nearest post office
        #...
        dispatcher.utter_message(text=f"The nearest post office to {post_code} is [insert post office name]")

class AskAboutServicesAction(Action):
    def name(self):
        return "ask_about_services"

    def run(self, dispatcher, tracker, domain):
        service_type = tracker.get_slot("service_type")
        # Call Royal Mail API to get information about service
        #...
        dispatcher.utter_message(text=f"We offer {service_type} services. Would you like to know more?")

class AskAboutPricesAction(Action):
    def name(self):
        return "ask_about_prices"

    def run(self, dispatcher, tracker, domain):
        price_range = tracker.get_slot("price_range")
        # Call Royal Mail API to get information about prices
        #...
        dispatcher.utter_message(text=f"Our prices start from {price_range[0]} and go up to {price_range[1]}")

Story

story:
  - intent: greet
    action: utter_greet
  - intent: track_package
    action: track_package_action
  - intent: find_post_office
    action: find_post_office_action
  - intent: ask_about_services
    action: ask_about_services_action
  - intent: ask_about_prices
    action: ask_about_prices_action

This is a basic implementation, and you'll need to customize it to fit your specific use case. You'll also need to implement the logic for tracking packages, finding post offices, and getting information about services and prices.

Note that this is just a starting point, and you'll need to integrate this chatbot with your Royal Mail API and handle errors and exceptions properly.
