Exporter une entrée vers un autre site WordPress

Cette requête exporte une entrée depuis ce site WordPress vers un site WordPress en aval.

Le plugin Gato GraphQL (version gratuite) doit être installé sur le site web en aval. Il doit exposer un endpoint avec "Nested mutations" activé.

Le paramètre $update indique s'il faut créer ou mettre à jour une entrée sur le site en aval.

Si l'entrée est mise à jour, l'identifiant commun entre les sites en amont et en aval est le slug de l'entrée.
