The official Stripe .NET library, supporting .NET Standard 2.0+, .NET Core 2.0+, and .NET Framework 4.6.1+.

Using the .NET Core command-line interface (CLI) tools:

dotnet add package Stripe.net

Using the NuGet Command Line Interface (CLI):

nuget install Stripe.net

Using the Package Manager Console:

Install-Package Stripe.net

From within Visual Studio:

1. Open the Solution Explorer.
2. Right-click on a project within your solution.
3. Click on Manage NuGet Packages...
4. Click on the Browse tab and search for "Stripe.net".
5. Click on the Stripe.net package, select the appropriate version in the right-tab and click Install.

For a comprehensive list of examples, check out the API documentation.

All of the service methods accept an optional RequestOptions object. This is used if you want to set an idempotency key, if you are using Stripe Connect, or if you want to pass the secret API key on each method.

var requestOptions = new RequestOptions();
requestOptions.ApiKey = "SECRET API KEY";
requestOptions.IdempotencyKey = "SOME STRING";
requestOptions.StripeAccount = "CONNECTED ACCOUNT ID";

You can configure the library with your own custom HttpClient:

StripeConfiguration.StripeClient = new StripeClient(
    apiKey,
    httpClient: new SystemNetHttpClient(httpClient));

Please refer to the Advanced client usage wiki page to see more examples of using custom clients, e.g. for using a proxy server, a custom message handler, etc.

The library automatically retries requests on intermittent failures like on a connection error, timeout, or on certain API responses like a status 409 Conflict. Idempotency keys are always added to requests to make any such subsequent retries safe.

By default, it will perform up to two retries. That number can be configured with StripeConfiguration.MaxNetworkRetries:

StripeConfiguration.MaxNetworkRetries = 0; // Zero retries

If you're writing a plugin that uses the library, we'd appreciate it if you identified using StripeConfiguration.AppInfo:

StripeConfiguration.AppInfo = new AppInfo
{
    Name = "MyAwesomePlugin",
    Url = "https://myawesomeplugin.info",
    Version = "1.2.34",
};

This information is passed along when the library makes calls to the Stripe API. Note that while Name is always required, Url and Version are optional.

The test suite depends on stripe-mock, so make sure to fetch and run it from a background terminal (stripe-mock's README also contains instructions for installing via Homebrew and other methods):

go get -u github.com/stripe/stripe-mock
stripe-mock

Run all tests from the src/StripeTests directory:

dotnet test

Run some tests, filtering by name:

dotnet test --filter FullyQualifiedName~InvoiceServiceTest

Run tests for a single target framework:

dotnet test --framework netcoreapp2.1

The library uses dotnet-format for code formatting. Code must be formatted before PRs are submitted, otherwise CI will fail. Run the formatter with:

dotnet format src/Stripe.net.sln
