Using Deepgram Management API (.NET SDK)

Administrative REST endpoints for projects, models, API keys, members, invites, usage, balances, and auth token grants.

When to use this product

• List or mutate projects.
• List models or per-project model availability.
• Manage keys, members, invites, scopes, usage, balances.
• Mint short-lived bearer tokens with GrantToken().

Use a different skill when:

• You want to run a live agent session → deepgram-dotnet-voice-agent.
• You want STT/TTS rather than project administration.

Authentication

dotnet add package Deepgram

using Deepgram;

Library.Initialize();
var manageClient = ClientFactory.CreateManageClient();
var authClient = ClientFactory.CreateAuthClient();

Both factory calls read credentials from the DEEPGRAMAPIKEY (or DEEPGRAMACCESSTOKEN) environment variable by default. To pass them explicitly: ClientFactory.CreateManageClient(apiKey: "...", options: ...) / ClientFactory.CreateAuthClient(apiKey: "...", options: ...). DeepgramHttpClientOptions throws if neither the env var nor an explicit credential is provided.

Quick start — projects and models

using Deepgram.Models.Manage.v1;

var client = ClientFactory.CreateManageClient();

var projects = await client.GetProjects();
var projectId = projects.Projects[0].ProjectId;

var project = await client.GetProject(projectId);
var models = await client.GetModels(new ModelSchema { IncludeOutdated = true });
var projectModels = await client.GetProjectModels(projectId);

Quick start — keys / invites / members / usage

var client = ClientFactory.CreateManageClient();
var projectId = (await client.GetProjects()).Projects[0].ProjectId;

var key = await client.CreateKey(projectId, new KeySchema()
{
    Comment = "MyTestKey",
    Scopes = new List<string> { "member" },
});

await client.SendInvite(projectId, new InviteSchema()
{
    Email = "[email protected]",
    Scope = "member",
});

var members = await client.GetMembers(projectId);
var usage = await client.GetUsageRequests(projectId, new UsageRequestsSchema());
var balances = await client.GetBalances(projectId);

Quick start — auth token grant

using Deepgram.Models.Auth.v1;
using Deepgram.Models.Authenticate.v1;

var authClient = ClientFactory.CreateAuthClient();
var token = await authClient.GrantToken(new GrantTokenSchema
{
    TtlSeconds = 300,
});

var bearerOptions = new DeepgramHttpClientOptions(accessToken: token.AccessToken);
var prerecordClient = ClientFactory.CreateListenRESTClient(options: bearerOptions);

Guard pattern for destructive operations

// 1. Verify the resource exists
var key = await client.GetKey(projectId, keyId);
Console.WriteLine($"Found key: {key.ApiKey.Comment} ({keyId})");

// 2. Delete
await client.DeleteKey(projectId, keyId);

// 3. Verify deletion succeeded
try
{
    await client.GetKey(projectId, keyId);
    Console.Error.WriteLine("ERROR: key still exists after deletion");
}
catch
{
    Console.WriteLine("Key deleted successfully.");
}

Gotchas

1. This repo does not currently expose Voice Agent configuration CRUD. Do not copy Python client.voice_agent.configurations.* examples into C#.
2. Destructive methods are irreversible. DeleteProject, DeleteKey, DeleteInvite, and RemoveMember should always use the verify-delete-verify pattern above.
3. Bearer-token auth is supported. DeepgramHttpClientOptions prefers explicit accessToken over apiKey, then env vars in that order.
4. Most sub-resources are project-scoped. Fetch a project ID first via GetProjects() before calling key/member/usage methods.
