Hi team! 👋 I'm having authentication issues with both Service Tokens AND Machine Identity in the .NET SDK (

Infisical.Sdk

). Issue 1: Service Token Authentication - .NET 8 - Service Token format:

<http://st.dev|st.dev>.xxx...

(valid format, starts with st.dev) - Token has Read permission for Development environment - Project ID verified - Result: Authentication fails ❌ Code:

csharp
var options = new ClientSettings
{
    Auth = new AuthenticationOptions
    {
        UniversalAuth = new UniversalAuthMethod
        {
            ClientId = serviceToken,
            ClientSecret = serviceToken
        }
    }
};

Issue 2: Machine Identity (Universal Auth) - Created Machine Identity with Viewer role (Permanent) - Added to project successfully - ClientId and ClientSecret generated and verified in dashboard - Error: "Machine Identity doesn't have permission to access environment" or similar auth failure Code:

csharp
var options = new ClientSettings
{
    Auth = new AuthenticationOptions
    {
        UniversalAuth = new UniversalAuthMethod
        {
            ClientId = "xxx...xxx", // Valid ClientId from dashboard
            ClientSecret = "xxx...xxx" // Valid ClientSecret from dashboard
        }
    }
};

var secrets = await client.ListSecretsAsync(new ListSecretsOptions
{
    ProjectId = projectId,
    Environment = "dev",
    SecretPath = "/"
});

What I've Verified: ✅ Machine Identity is added to project with Viewer role ✅ Role shows "Permanent" duration ✅ ClientId and ClientSecret copied correctly from Universal Auth tab ✅ Project ID is correct ✅ Service Token is valid and has Read permission for dev environment Questions: 1. What's the correct .NET SDK authentication pattern for Service Tokens? 2. Why would Machine Identity fail despite correct permissions in dashboard? 3. Do I need to explicitly grant environment-level access to Machine Identity somewhere? 4. Is there a working .NET SDK example with either authentication method? Happy to provide more debugging info via DM or private channel if needed! Thanks! 🙏

Hey @Muhammed, Are you using the Europe or US region?

I am using Europe

Confirm if you’re setting up the eu host:

var settings = new InfisicalSdkSettingsBuilder()
        .WithHostUri("<http://localhost:8080>") // Optional. Will default to <https://app.infisical.com>

In your case it should be: https://eu.infisical.com

yes now all is done but i have another problem for pro app I'm experiencing a critical payment authorization issue preventing me from upgrading to Pro. **ERROR MESSAGE:**"We cannot authorize your payment method. Please choose a different payment method and try again." SITUATION:- Instance: EU (https://eu.infisical.com) - Account: muhammed@techliberty.co - Organization: TechLiberty - Location: Turkey 🇹🇷 **PAYMENT ATTEMPTS (ALL FAILED):**1. ✅ Visa Credit Card (verified, international enabled) - Balance: Sufficient - Used successfully: AWS, GitHub, DigitalOcean, Stripe merchants - Result: ❌ "Cannot authorize" 2. ✅ Mastercard Credit Card (verified, international enabled) - 3D Secure: Enabled - Used successfully: Google Cloud, Azure (before boycott) - Result: ❌ "Cannot authorize" 3. ✅ Link Payment - Result: ❌ Failed **ROOT CAUSE (Suspected):**This appears to be a Stripe country restriction for Turkey, not a card issue. Our cards work perfectly with other international SaaS providers. **URGENT REQUEST:**We need Pro features for production deployment ASAP. Can you provide alternative payment methods?
