  **Request Syntax**
  ::

    response = client.list_archives(
        NamePrefix='string',
        EventSourceArn='string',
        State='ENABLED'|'DISABLED'|'CREATING'|'UPDATING'|'CREATE_FAILED'|'UPDATE_FAILED',
        NextToken='string',
        Limit=123
    )
    
  :type NamePrefix: string
  :param NamePrefix: 

    A name prefix to filter the archives returned. Only archives with name that match the prefix are returned.

    

  
  :type EventSourceArn: string
  :param EventSourceArn: 

    The ARN of the event source associated with the archive.

    

  
  :type State: string
  :param State: 

    The state of the archive.

    

  
  :type NextToken: string
  :param NextToken: 

    The token returned by a previous call, which you can use to retrieve the next set of results.

     

    The value of ``nextToken`` is a unique pagination token for each page. To retrieve the next page of results, make the call again using the returned token. Keep all other arguments unchanged.

     

    Using an expired pagination token results in an ``HTTP 400 InvalidToken`` error.

    

  
  :type Limit: integer
  :param Limit: 

    The maximum number of results to return.
