# Créer ou modifier une entrée

Nécessite `sites:write`. Ne coûte aucun crédit. La modification ne concerne que le brouillon. Les visiteurs ne voient rien tant que vous n’avez pas [publié](/docs/api/publishing/publish).

Un champ invalide est refusé avec un `400` qui indique son nom, et rien n’est écrit. Si la collection comporte un champ de brouillon, toute nouvelle entrée est créée en tant que brouillon. Une personne peut ensuite décider de la publier.

Envoyez `create_only: true` pour refuser la requête plutôt que d’écraser une entrée existante, ou `expected_hash` pour ne remplacer que la version que vous avez lue.

```http
PUT https://api.atelier201.com/v1/sites/{site_id}/content/{collection}/{slug}
```
