Attributes synced from a CRM integration only accept `prompt`, `should_prompt_override` and `is_visible`. **Scope requis :** `CRM_WRITE` Cet endpoint effectue une mise à jour partielle. Seuls les champs envoyés sont modifiés. `key` et `type` ne peuvent pas être modifiés. ## Champs du body | Champ | Type | Description | | - | - | - | | `label` | string | Nouveau nom affiché | | `options` | array | Remplace toute la liste d'options avec des objets `{ label, key? }`. Attributs `DROPDOWN` uniquement | | `prompt` | string | Consigne pour l'AI CRM Manager. Une valeur vide l'efface | | `should_prompt_override` | boolean | Indique si l'IA peut écraser une valeur déjà renseignée | | `is_visible` | boolean | Affiche ou masque l'attribut dans les apps Allo | ## Renommer des options Les clés d'options restent stables. Pour renommer une option, envoyez sa `key` actuelle avec le nouveau `label`. Une option envoyée sans `key` correspondante est considérée comme nouvelle et reçoit une clé dérivée de son label. Les options absentes de la liste sont supprimées. ## Attributs synchronisés depuis un CRM Un attribut dont la `source` n'est pas `allo` est géré par votre intégration CRM. Seuls `prompt`, `should_prompt_override` et `is_visible` peuvent être modifiés. Envoyer `label` ou `options` renvoie `409 ATTRIBUTE_MANAGED_BY_INTEGRATION`. ## Réponse Renvoie `200` avec l'attribut mis à jour, dans le même format que [Lister les attributs d'entreprise](/fr/v2/api-reference/crm/list-company-attributes). ## Erreurs | Statut | Code | Quand | | - | - | - | | `400` | `ATTRIBUTE_LABEL_INVALID` | `label` est vide, dépasse 255 caractères ou ne contient ni lettre ni chiffre | | `400` | `ATTRIBUTE_OPTION_INVALID` | `options` est vide, ou un label d'option est vide, dépasse 255 caractères ou est en doublon | | `400` | `ATTRIBUTE_OPTIONS_NOT_SUPPORTED` | `options` envoyé pour un attribut qui n'est pas `DROPDOWN` | | `403` | `API_KEY_INSUFFICIENT_SCOPE` | La clé n'a pas le scope `CRM_WRITE` | | `404` | `TEAM_NOT_FOUND` | Le workspace n'utilise pas le nouveau modèle de contacts | | `404` | `ATTRIBUTE_NOT_FOUND` | Aucun attribut avec cette clé | | `409` | `ATTRIBUTE_MANAGED_BY_INTEGRATION` | `label` ou `options` envoyés pour un attribut géré par une intégration CRM | | `409` | `ATTRIBUTE_CONCURRENT_MODIFICATION` | Les attributs ont été modifiés en même temps.
