A general medium of bot API acts as a barrier that requests data access from the database of any other software and delivers it back to the chatbot. Let’s find out how chatbot API works in simple steps.

Message processing is the step where the API chatbot receives input from the user. Later process the acquired input or message using NLP (Natural Language Processing) techniques to understand user intent. Moreover, NLP helps chatbot APIs extract information and determine the desired response.

2. Intent Recognition: From words to goals as step two

what the user is trying to say. Comprises with advanced computing, chatbot API analyzes the input and identifies keywords, which it then directs to predefined intents.

4. Deliver Response: Ended as AI to human as step four

The chatbot API returns the generated response to the user’s application via the response endpoints of the API. The response could be in plain text, XML, JSON, or another format entirely, depending on how the API is built.
