To retrieve the ID of the last version added to the connector definition, use the ``get-connector-definition`` command and check the ``LatestVersion`` property. ::

    aws greengrass get-connector-definition-version \
        --connector-definition-id "b5c4ebfd-f672-49a3-83cd-31c7216a7bb8" \
        --connector-definition-version-id "63c57963-c7c2-4a26-a7e2-7bf478ea2623"
