  title: Amazon EventBridge Create Rule with Targets
  summary: Create a rule on an existing event bus, attach targets, and verify them.
  description: >-
    Defines a new pattern-matching rule on an existing event bus, attaches the
    supplied targets to it, and reads the targets back to confirm the rule is
    wired up. Useful for adding routing onto the default or a pre-existing event
    bus without provisioning a new one. Every step spells out its AWS JSON
    request inline — including the documented X-Amz-Target header — so the flow
    can be read and executed without opening the underlying OpenAPI description.
