Building a Chatbot with Amazon Lex

Building a chatbot with Amazon Lex involves several key steps to create a functional and intelligent assistant. Here’s a simplified breakdown of the process:

1. Start by specifying the actions your chatbot should take in response to user input, called "intents."
2. Create slots, which are the pieces of information your bot needs to fulfill a user's request. Think of slots as questions the bot will ask the user to gather the necessary data.
3. Set up fulfillment. This step involves determining how your bot will execute the intents, such as invoking AWS Lambda functions or accessing other backend services.
