You can now use the Amazon WorkMail API to programmatically receive Exchange Web Services (EWS) push notifications when events occur in your mailboxes, such as email delivery or calendar updates. This enables your services, applications, and workflows to respond in real-time to events in your mailboxes. For example, you can create a workflow that uses EWS push notifications with AWS Lambda, Amazon API Gateway, and Amazon Comprehend to analyze the sentiment of your incoming email. Visit our GitHub page for sample code to get started.
