I understand this is a long shot, but I have been looking for a chatbot that allows for injecting "hidden" data into the chatbot so it automatically knows about the client even before they start the chat.
So when a client uses their custom link, the chatbot knows about their business by retrieving information from the URL, like:
chatbot-url.com?info="Roxy LLC is a fashion brand that sells unique t-shirts that never need to be washed."

I understand I can create one chatbot for that client, but I need a more dynamic solution.
