IoT / Client / list_things



Lists your things. Use the attributeName and attributeValue parameters to filter your things. For example, calling ListThings with attributeName=Color and attributeValue=Red retrieves all things in the registry that contain an attribute Color with the value Red. For more information, see List Things from the Amazon Web Services IoT Core Developer Guide.

Requires permission to access the ListThings action.


You will not be charged for calling this API if an Access denied error is returned. You will also not be charged if no attributes or pagination token was provided in request and no pagination token and no results were returned.
