Since your bot is going to receive chat messages in everyday language from a person, it needs integration with one of the Natural Language Processing (NLP) services to extract intents and entities out of the message in plain language. NLP empowers bots to strike natural conversation with a human, and is available as APIs from Google, Microsoft, IBM and Facebook. Luckily, you don’t have to write your own NLP algorithm. Natural languages processingĪn integral part of a chatbot development is the integration with Natural Languages Processing (NLP) services. However, they, in general, follow the exercise of adding an endpoint to send and receive chat messages that depend on access tokens authorization.įurther, you must bring some channel-specific UI by integrating quick reply buttons under chat bubbles, or visual cards relevant to the conversation going on.įor instance, Facebook Messenger allows conversation rich UI using JavaScript, HTML and CSS by means of full WebView. Once the backend is in place, you must create modules to integrate with each channel. The total time to setup server and deploy backend with AWS, Node.js and Microsoft Bot Framework takes around 4 hours. ![]() NET and Node.js server-side SDKs, so you can securely choose the programming language of your choice.

The backend enforces business logic, enables integrations with existing systems, makes the bot intelligent, and, thus, leads the conversation with the user. Did you compare WhatsApp on iOS and Android lately? Implementation of a chatbot Backend DevelopmentĪ chatbot needs a backend to manage an incoming stream of messages from multi-channels and parse them with NLP services such as Watson Conversation, Facebook’s Wit.ai, Api.ai, or LUIS. We live in the world of multi-platform development with each platform having its unique design language and, thus, UI. The UI or frontend of a chatbot matches the platform it is targeted on: Messenger, Slack, Telegram, etc., which reduces the development time considerably. However, unlike conventional software and mobile applications, chatbots do not need chic UI design, provision for numerous mobile platforms, extended development cycles with the app store reviews, and exclusive acquisition strategies to draw users into apps.īut they still require the conventional software modules like backend to be built around them. And as with most pieces of software, apps, and programs, it all comes down to feature sets, structure, and value. My point is there are no certain rules regarding how much time goes into developing a chatbot. Did you know you can create a Messenger chatbot without writing a single line of code with Chatfuel in a couple of hours? I, myself, created one, to bring leads on my Facebook Page, in less than an hour. ![]()
