✅ Microsoft Graph API

Hello I need to create program that will load data from Outlook calendar, which is done using Microsoft Graph API, so i have this code:

var scopes = new[] { "https://graph.microsoft.com/.default" };

// Multi-tenant apps can use "common",
// single-tenant apps must use the tenant ID from the Azure portal
var tenantId = "teanantid";

// Values from app registration
var clientId = "clientid";
var clientSecret = "clientsecret";

// 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 x = await graphClient.Users["clientid"].Request().GetAsync();

var scopes = new[] { "https://graph.microsoft.com/.default" };

// Multi-tenant apps can use "common",
// single-tenant apps must use the tenant ID from the Azure portal
var tenantId = "teanantid";

// Values from app registration
var clientId = "clientid";
var clientSecret = "clientsecret";

// 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 x = await graphClient.Users["clientid"].Request().GetAsync();

Got from here: https://learn.microsoft.com/en-us/graph/sdks/choose-authentication-providers?tabs=CS#client-credentials-provider But im getting this error:

Code: Authorization_RequestDenied
Message: Insufficient privileges to complete the operation.

check the docs of what permissions this function requires

are you using the right token? maybe you've got multiple

Kukuba008OP•2y ago

it should be the right one, i have tryied it many times, with different ones

Anton•2y ago

does it work if you give it ReadWrite? are you sure it's not using the group category?

Kukuba008OP•2y ago

No idea sorry, i dont have permissions for azure, so i always have to ask someone to give them to me, i will ask them to regenerate the tokens, and allow the group calendar, which will most likely take more than day. So thanks for help, and i will be back tomorrow (if it breaks after that).

for the record, I haven't used these tools ever, I'm just giving you my best guesses

Kukuba008OP•2y ago
