.. py:method:: LexModelBuildingService.Client.get_slot_type_versions(**kwargs)

  

  Gets information about all versions of a slot type.

   

  The ``GetSlotTypeVersions`` operation returns a ``SlotTypeMetadata`` object for each version of a slot type. For example, if a slot type has three numbered versions, the ``GetSlotTypeVersions`` operation returns four ``SlotTypeMetadata`` objects in the response, one for each numbered version and one for the ``$LATEST`` version.

   

  The ``GetSlotTypeVersions`` operation always returns at least one version, the ``$LATEST`` version.

   

  This operation requires permissions for the ``lex:GetSlotTypeVersions`` action.
