Answer 1

If you are trying to get the messages with C# code , you should try with below code

GraphServiceClient graphClient = new GraphServiceClient( authProvider );  
  
var message = await graphClient.Me.Messages["{message-id}"]  
	.Request()  
	.GetAsync();  

Ref doc - https://learn.microsoft.com/en-us/graph/api/message-get?view=graph-rest-1.0&tabs=csharp

Hi @SAC_535

You can call the endpoint using the C# Graph SDK, and since /users/{user id} only supports application contexts, you need to use the client credentials flow to get a token. Please refer to the complete code:

using Azure.Identity;   
using Microsoft.Graph;  
using Newtonsoft.Json;  
      
var scopes = new[] { "https://graph.microsoft.com/.default" };  
  
var tenantId = "{tenant id}";  
  
// Values from app registration  
var clientId = " {client id}";  
var clientSecret = "{client secret}";  
  
// using Azure.Identity;  
var options = new TokenCredentialOptions  
{  
    AuthorityHost = AzureAuthorityHosts.AzurePublicCloud  
};  
  
// https://learn.microsoft.com/dotnet/api/azure.identity.clientsecretcredential  
var clientSecretCredential = new ClientSecretCredential(  
    tenantId, clientId, clientSecret, options);  
  
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);  
  
var message = await graphClient.Users["{user id}"].Messages["{message id}"]  
      .Request()  
      .GetAsync();  
  
Console.WriteLine("message:" + JsonConvert.SerializeObject(message));
