Invoke

Invoke a Lambda function.

Invocations may be synchronous or asynchronous. In a synchronous invocation, Lambda waits for a response that contains details or errors. In an asynchronous invocation, Lambda adds an event to a queue. After the event is sent, the response includes a status code only.
