Exportar una entrada a otro sitio WordPress

Esta consulta exporta una entrada desde este sitio WordPress hacia algún sitio WordPress downstream.

El plugin Gato GraphQL (versión gratuita) debe estar instalado en el sitio web downstream. Debe exponer un endpoint con "Nested mutations" habilitado.

El parámetro $update indica si se debe crear o actualizar una entrada en el sitio downstream.

Si se actualiza la entrada, el identificador común entre los sitios upstream y downstream es el slug de la entrada.
