1. Click the `InputOutputProcessingMachine` state machine from the Step Functions console.
2. Click on **Start execution** and use the JSON below as your input payload.
   :::code{showCopyAction=true showLineNumbers=false language=json}
   {
   "comment": "An input comment.",
   "data": {
   "value1": 23,
   "value2": 17
   },
   "extra": "foo",
   "lambda": {
   "who": "AWS Step Functions"
   }
   }
   :::
3. Once the execution is successful, review the output in the `Execution output` tab. Notice how the data block in the input json is added to the output of the Lambda function. This output would be passed to the next state in your workflow.
