  * Function name - my-function (name-only), my-function:v1 (with alias).

  * Partial ARN - 123456789012:function:my-function.

#### InvocationType

In case of RequestResponse, Action will wait till Lambda function execution is completed. Event invocation type will complete action immediately, without waiting for Lambda response.

#### Function

* Javascript code to supply dynamic data to lambda function.
* "payload" object coming from rule or action trigger is available in this code, function can be used to modify payload before sending to lambda.

```
//Example 1

payload["speed"] = (payload.speed*5)/18; 
//Convert data on the go from km/hr to m/s.
```

#### Connection ID
