Real world examples
- SendGrid, an email API, sends events whenever an email is processed, delivered, opened etc... (https://sendgrid.com/docs/API_Reference/Webhooks/event.html)
- Chargify, a billing API, exposes payment activity through various events (https://docs.chargify.com/api-events)
- Amazon's AWS Lambda, lets you execute code in response to events such as changes to Amazon S3 buckets, updates to an Amazon DynamoDB table, or custom events generated by your applications or devices. (https://aws.amazon.com/lambda)
- MySQL runs triggers based on events such as inserts and update events happening on database tables.
