ReceiveMessageRequest

A list of attributes that need to be returned along with each message. These attributes include:

The maximum number of messages to return. Amazon SQS never returns more messages than this value (however, fewer messages might be returned). Valid values: 1 to 10. Default: 1.

The name of the message attribute, where N is the index.

The URL of the Amazon SQS queue from which messages are received.

This parameter applies only to FIFO (first-in-first-out) queues.

The duration (in seconds) that the received messages are hidden from subsequent retrieve requests after being retrieved by a ReceiveMessage request.

The duration (in seconds) for which the call waits for a message to arrive in the queue before returning. If a message is available, the call returns sooner than WaitTimeSeconds. If no messages are available and the wait time expires, the call returns successfully with an empty list of messages.
