Utilization

To send text, image and buttons you can just go do a

dispatcher.utter_message(text = str, image = "", buttons = [])

sms_modifier.py automatically converts the text, image, buttons to a single text message.

---

To restart a conversation, you have to write in actions.py

dispatcher.utter_message(json_message = {"cmd": "restart"})

This will create the data in the users_data.json file and works as same as rasa's restart

To neglect the user message, you have to write in actions.py

dispatcher.utter_message(json_message = {"cmd" : "neglect"})

This will check whether a payload is available and if not the same user message in text will be sent to rasa server. If there is a payload then the corresponding payload will be send to rasa server

Note: You are always welcomed to implement your own commands. Make sure the working of the command is written in executeCommands function of checkElements class in sms_modifier.py file

Usage

To change RASA server URL, go to whatsapp.py and change

RASA_URL = "http://localhost:5005/webhooks/rest/webhook/"

to your RASA server URL

If you wish to change the database from JSON to any other database you can find methods in sms_modifier.py. You have to change StoreTemporaryData and JSONModifier classes and update the methods.

Also do not forget to change the TODO section in whatsapp.py to your service provider API
