The application serves as the backend for a chatbot, enabling users to interact with it through various commands and actions. Here's a detailed description of its functionality: Users initiate interactions with the chatbot by sending a message or clicking on an interactive card element in the chatbot interface. The application receives and processes these interactions, which are sent as POST requests with JSON data. The application processes user actions in two main ways: Card Click Events & Slash Commands. For certain commands and actions, the application interacts with external databases and systems to fetch or update data, perform authorization checks, and carry out other server-side operations.
