Stripe.Net Integration with IronPDF

Stripe.Net is a powerful .NET library that allows developers to integrate Stripe's payment processing capabilities into .NET applications. Stripe is a popular payment gateway that enables businesses to accept payments online. With Stripe.Net, developers can manage transactions, customers, subscriptions, and more using the robust features provided by the Stripe API. In this article, we will discuss how to use Stripe with IronPDF to create PDFs.

Getting Started with Stripe.Net

Create a New Visual Studio Project

To get started with Stripe.Net, we need to create a new Visual Studio project or open an existing one. For this tutorial, we will use a Console Application project.

1. Open Visual Studio and click on "Create a New Project".

   

2. A new window will appear. Select Console Application and click on Next.

   

3. In the next window, enter your project name and select the location, then click on Next.

   

4. In the next window, select the framework and click on Create.

   

Just like that, your new Visual Studio Console Application project is created.

Installation

To start using Stripe.Net in your project, you need to install the Stripe.Net package via NuGet. You can do this using the Package Manager Console or the NuGet Package Manager in Visual Studio.

Using the Package Manager Console:

Install-Package Stripe.net

Or

dotnet add package Stripe.net

Using the NuGet Package Manager, search for "Stripe.net" and install the package.

Configuration

Once installed, you need to configure your Stripe API key, which you can find on your Stripe account. This key is essential for authenticating your requests to the Stripe API. Typically, this key is stored in a configuration file or environment variable for security purposes.

Here’s an example of how to set up your API key:

StripeConfiguration.ApiKey = "your_secret_api_key";

StripeConfiguration.ApiKey = "your_secret_api_key";

StripeConfiguration.ApiKey = "your_secret_api_key"

Basic Operations with Stripe.Net

Creating a Customer

Creating a customer is one of the fundamental operations when working with Stripe.Net. Customers can be associated with payment methods and subscriptions.

var options = new CustomerCreateOptions
{
    Email = "customer@example.com",
    Name = "John Doe",
};
var service = new CustomerService();
Customer customer = service.Create(options);

var options = new CustomerCreateOptions
{
    Email = "customer@example.com",
    Name = "John Doe",
};
var service = new CustomerService();
Customer customer = service.Create(options);

Dim options = New CustomerCreateOptions With {
	.Email = "customer@example.com",
	.Name = "John Doe"
}
Dim service = New CustomerService()
Dim customer As Customer = service.Create(options)

Creating a Payment Intent

A PaymentIntent is an object that represents a payment process in Stripe. It is designed to track the lifecycle of a payment from creation through completion.

var options = new PaymentIntentCreateOptions
{
    Amount = 2000,
    Currency = "usd",
    PaymentMethodTypes = new List<string>
    {
        "card",
    },
};
var service = new PaymentIntentService();
PaymentIntent paymentIntent = service.Create(options);

var options = new PaymentIntentCreateOptions
{
    Amount = 2000,
    Currency = "usd",
    PaymentMethodTypes = new List<string>
    {
        "card",
    },
};
var service = new PaymentIntentService();
PaymentIntent paymentIntent = service.Create(options);

Dim options = New PaymentIntentCreateOptions With {
	.Amount = 2000,
	.Currency = "usd",
	.PaymentMethodTypes = New List(Of String) From {"card"}
}
Dim service = New PaymentIntentService()
Dim paymentIntent As PaymentIntent = service.Create(options)

Advanced Features

Subscriptions

Stripe supports various subscription models, and managing subscriptions via Stripe.Net is straightforward. You can create, update, and cancel subscriptions.

var options = new SubscriptionCreateOptions
{
    Customer = "cus_123456789",
    Items = new List<SubscriptionItemOptions>
    {
        new SubscriptionItemOptions
        {
            Plan = "plan_123456789",
        },
    },
};
var service = new SubscriptionService();
Subscription subscription = service.Create(options);

var options = new SubscriptionCreateOptions
{
    Customer = "cus_123456789",
    Items = new List<SubscriptionItemOptions>
    {
        new SubscriptionItemOptions
        {
            Plan = "plan_123456789",
        },
    },
};
var service = new SubscriptionService();
Subscription subscription = service.Create(options);

Dim options = New SubscriptionCreateOptions With {
	.Customer = "cus_123456789",
	.Items = New List(Of SubscriptionItemOptions) From {
		New SubscriptionItemOptions With {.Plan = "plan_123456789"}
	}
}
Dim service = New SubscriptionService()
Dim subscription As Subscription = service.Create(options)

Handling Disputes

Disputes occur when a customer questions a charge with their bank or credit card company. Stripe.Net allows you to list, retrieve, and respond to disputes.

var service = new DisputeService();
Dispute dispute = service.Get("dp_123456789");

var service = new DisputeService();
Dispute dispute = service.Get("dp_123456789");

Dim service = New DisputeService()
Dim dispute As Dispute = service.Get("dp_123456789")

Best Practices

1. Security: Always secure your API keys and never hard-code them in your source files.
2. Error Handling: Implement robust error handling to manage exceptions and failed API calls.
3. Testing: Use Stripe’s test mode and provide test card numbers to thoroughly test your integration.
4. Documentation: Refer to the official Stripe API documentation and the Stripe.Net library documentation for up-to-date information and examples.
