.. py:method:: IoTFleetWise.Client.list_signal_catalogs(**kwargs)

  

  Lists all the created signal catalogs in an Amazon Web Services account.

   

  You can use to list information about each signal (node) specified in a signal catalog.

   

  .. note::

    

    This API operation uses pagination. Specify the ``nextToken`` parameter in the request to return more results.

  **Request Syntax**
  ::

    response = client.list_signal_catalogs(
        nextToken='string',
        maxResults=123
    )
    
  :type nextToken: string
  :param nextToken: 

    A pagination token for the next set of results.

     

    If the results of a search are large, only a portion of the results are returned, and a ``nextToken`` pagination token is returned in the response. To retrieve the next set of results, reissue the search request and include the returned token. When all results have been returned, the response does not contain a pagination token value.

    

  
  :type maxResults: integer
  :param maxResults: 

    The maximum number of items to return, between 1 and 100, inclusive.
