# .NET Server SDK

> The [Fingerprint Server C#/.NET SDK](https://github.com/fingerprintjs/dotnet-sdk) is an easy way to interact with our Server API from your .NET application. You can retrieve visitor history or individual identification events. View our [.NET Server SDK quickstart](/docs/dotnet-server-quickstart) for a step-by-step guide to get started.

### How to install

Install the package from NuGet.

```bash Bash theme={"theme":"github-dark-dimmed"}
dotnet add package Fingerprint.ServerSdk
```

Initialize the client instance and use it to make API requests. You need to specify your secret API key and region (if it is not US/Global).

```csharp C# theme={"theme":"github-dark-dimmed"}
using Fingerprint.ServerSdk.Api;
using Fingerprint.ServerSdk.Extensions;
using Fingerprint.ServerSdk.Client;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddFingerprint(options =>
{
    options.AddTokens(new BearerToken("SECRET-API-KEY"));
    // options.Region = Region.Eu;
});

var app = builder.Build();
var api = app.Services.GetRequiredService<IFingerprintApi>();

// Search events
var events = await api.SearchEventsAsync(new SearchEventsRequest().WithVisitorId("VISITOR_ID"));
Console.WriteLine(events.Ok());

// Get a specific identification event
var getEvent = api.GetEventAsync("EVENT_ID");
Console.WriteLine(getEvent.Ok());
```
