- A dynamic chatbot that demonstrates how to integrate a chatbot with a back-end database, such as Amazon DynamoDB, to build an automated order taking service (in this example, a pizza ordering service).
- When the customer starts their order, the chatbot retrieves the pizza menu from the back-end database, and displays it to the customer.
- The chatbot interacts with the customer to extract order details (for example, type and size of the pizza) and confirms the order.
- The order history is stored in a DynamoDB table, which helps facilitate a personalized customer experience.
- Functionality to automatically extract user's email, used by Amazon Cognito to authenticate the user with Amazon API Gateway, to use it as customerId.
- Support for using API keys to get weather data.
- Functionality to write customer feedback to DynamoDB.
- Synchronized audio and text response in sample web client.
- Cognito with Amplify javascript framework to have sign-in/register in place for secure access to the web application.
- Encryption to all S3 and logging S3 buckets.
- Cloudfront to the web app hosted in S3. Restricted access to the web app S3 bucket to Cloudfront only.
