Ejemplo 2: Importación de un mensaje

En el ejemplo siguiente se muestra cómo importar un mensaje. Para obtener más información, consulte Importación de mensajes en chats y canales de Microsoft Teams mediante Microsoft Graph.

Importante

CreatedDateTime debe ser único en milisegundos dentro del chat de destino. Si existe un mensaje con el mismo createdDateTime , se produce un error en la solicitud con 409 Conflict. Ajuste createdDateTime y vuelva a intentarlo. Para obtener más información, consulte Importación de mensajes en chats y canales de Microsoft Teams mediante Microsoft Graph.
