Invoke

Invoke an AWS Lambda function.

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