Targets are the resources that can be invoked when a rule is triggered. For example, AWS Lambda functions, Amazon Kinesis streams, and built-in targets.
Input and InputPath are mutually-exclusive and optional parameters of a target. When a rule is triggered due to a matched event, if for a target:
- Neither Input nor InputPath is specified, then the entire event is passed to the target in JSON form.
- InputPath is specified in the form of JSONPath (e.g. $.detail), then only the part of the event specified in the path is passed to the target (e.g. only the detail part of the event is passed).
- Input is specified in the form of a valid JSON, then the matched event is overridden with this constant.
