Use AWS Lex, Kendra and Comprehend to deploy a conversational chatbot with WhatsApp. The bot can answer frequently asked questions, schedule appointments, and indicate the conversation sentiment through WhatsApp. Any escalations can be passed to a human agent to Twilio Flex.

• Use Amazon Lex's Natural Language Undestanding (NLU) engine to recognize the intent of the text, automatically respond to frequently asked questions, and schedule appointments
• Connect to Twilio Flex using an AWS Lambda when users request help from a human
• When a user requests to speak to an agent, Amazon Comprehend captures the sentiment of the conversation

Use this for appointment scheduling and with any knowledge base for a better FAQ user experience.
