Idempotent HTTP requests with Amazon EventBridge API Destinations
EventBridge rule → Connection → API
Create an EventBridge event bus and API Destination to reliably send events to HTTP APIs.
This pattern describes how to use EventBridge API Destinations with the IETF HTTP Idempotency-Key header to invoke HTTP APIs supporting idempotent API operations.
Using API destinations, you can route events between AWS services, integrated software as a service (SaaS) applications, and your applications outside of AWS by using API calls.
