Stripe.net

Stripe.net is a full service .net api for http://stripe.com. It includes support for Plans, Tokens, Customers, Charges, Subscriptions, Invoices, and Events.

For more information about the examples below, you can visit https://stripe.com/docs/api for a full reference.

Quick Start

Add a reference to Stripe.net.dll (You can find a pre-compiled version in the build folder of this repository or install Stripe.net via NuGet)

Add an AppSetting with your api key

<appSettings>
...
	<add key="StripeApiKey" value="[your api key here]" />
...
</appSettings>

Use the library :)

Examples

Plans

Creating a plan

If your site has multiple offerings, plans are perfect. You can create as many plans as you want and then just assign customers to those plans later on.

var myPlan = new StripePlanCreateOptions();
myPlan.AmountInCents = 1000;	// all amounts on Stripe are in cents
myPlan.Currency = "usd";		// "usd" only supported right now
myPlan.Interval = "month";		// "month" or "year"
myPlan.Name = "Bronze";
myPlan.TrialPeriodDays = 30;	// amount of time that will lapse before the customer is billed

var planService = new StripePlanService();
StripePlan response = planService.Create(myPlan);

The returned StripePlan entity above will have a unique Id. You will want to persist this for later. When you create a customer you will be able to assign them to a plan id (or not)

Retrieving a plan

var planService = new StripePlanService();
StripePlan response = planService.Get(*planId*);

Deleting a plan

var planService = new StripePlanService();
planService.Delete(*planId*);

List all plans

var planService = new StripePlanService();
IEnumerable<StripePlan> response = planService.List(); // can optionally pass count (defaults to 10) and offset

Coupons (queue-pons not coo-pons)

Creating a coupon

var myCoupon = new StripeCouponCreateOptions();
myCoupon.Id = "HOLIDAY10OFF";
myCoupon.PercentOff = "10";
myCoupon.Duration = "repeating";	// "forever", "once", or "repeating"
myCoupon.DurationInMonths = 3;		// valid when "repeating" only

// set these if you want to
myCoupon.MaxRedemptions = 100;
myCoupon.RedeemBy = '12/31/2012';

var couponService = new StripeCouponService();
StripeCoupon response = couponService.Create(myCoupon);

Retrieving a coupon

var couponService = new StripeCouponService();
StripeCoupon response = couponService.Get(*couponId*);

Deleting a coupon

var couponService = new StripeCouponService();
couponService.Delete(*couponId*);

List all coupons

var couponService = new StripeCouponService();
IEnumerable<StripeCoupon> response = couponService.List();	// can optionally pass count (defaults to 10) and offset

Tokens

Creating a token

A token can be used anywhere on Stripe where you would normally pass a card. Once it's created, it can be used on a customer or a charge, but only used once.

var myToken = new StripeTokenCreateOptions();
myToken.CardAddressCountry = "US";
myToken.CardAddressLine1 = "24 Portal St";
myToken.CardAddressLine2 = "Unit B";
myToken.CardAddressState = "NC";
myToken.CardAddressZip = "27617";
myToken.CardCvc = "1223";
myToken.CardExpirationMonth = "10";
myToken.CardExpirationYear = "2012";
myToken.CardName = "Gabe Newell";
myToken.CardNumber = "4242424242424242";
myToken.AmountInCents = 5153;
myToken.Currency = "usd";

var tokenService = new StripeTokenService();
StripeToken stripeToken = tokenService.Create(myToken);

Tokens are very useful if you don't want to store the customers credit card information on your servers (very good for pci compliance).

Retrieving a token

var tokenService = new StripeTokenService();
StripeToken stripeToken = tokenService.Get(*tokenId*);

Customers

Creating a customer

When creating a customer, you can specify any plan they are on, any coupons that will apply, a credit card or token, and various meta data.

var myCustomer = new StripeCustomerCreateOptions();

// set these properties if it makes you happy
myCustomer.Email = "[email protected]";
myCustomer.Description = "Johnny Tenderloin ([email protected])";

// set these properties if using a card
myCustomer.CardNumber = "4242424242424242";
myCustomer.CardExpirationYear = "2012";
myCustomer.CardExpirationMonth = "10";
myCustomer.CardAddressCountry = "US";				// optional
myCustomer.CardAddressLine1 = "24 Beef Flank St";	// optional
myCustomer.CardAddressLine2 = "Apt 24";				// optional
myCustomer.CardAddressState = "NC";					// optional
myCustomer.CardAddressZip = "27617";				// optional
myCustomer.CardName = "Joe Meatballs";				// optional
myCustomer.CardCvc = "1223";						// optional

// set this property if using a token
myCustomer.TokenId = *tokenId*;

myCustomer.PlanId = *planId*;								// only if you have a plan
myCustomer.Coupon = *couponId*;							// only if you have a coupon
myCustomer.TrialEnd = DateTime.UtcNow.AddMonths(1);		// when the customers trial ends (overrides the plan if applicable)

var customerService = new StripeCustomerService();
StripeCustomer stripeCustomer = customerService.Create(myCustomer);

Don't let this be intimidating - all of these fields are optional. You could just create a customer with an email if you wanted.

Updating a customer

var myCustomer = new StripeCustomerUpdateOptions()

// set these properties if it makes you happy
myCustomer.Email = "[email protected]";
myCustomer.Description = "Johnny Tenderloin ([email protected])";

// set these properties if using a card
myCustomer.CardNumber = "4242424242424242";
myCustomer.CardExpirationYear = "2012";
myCustomer.CardExpirationMonth = "10";
myCustomer.CardAddressCountry = "US";				// optional
myCustomer.CardAddressLine1 = "24 Beef Flank St";	// optional
myCustomer.CardAddressLine2 = "Apt 24";				// optional
myCustomer.CardAddressState = "NC";					// optional
myCustomer.CardAddressZip = "27617";				// optional
myCustomer.CardName = "Joe Meatballs";				// optional
myCustomer.CardCvc = "1223";						// optional

// set this property if using a token
myCustomer.TokenId = *tokenId*;

myCustomer.Coupon = *couponId*;		// only if you have a coupon

var customerService = new StripeCustomerService();
StripeCustomer stripeCustomer = customerService.Update(*customerId*, myCustomer);

Retrieving a customer

var customerService = new StripeCustomerService();
StripeCustomer stripeCustomer = customerService.Get(*customerId*);

Deleting a customer

Customers that are deleted can still be retrieved through the api. The Deleted property will be set to true if they are deleted.

var customerService = new StripeCustomerService();
customerService.Delete(*customerId*);

List all customers

var customerService = new StripeCustomerService();
IEnumerable<StripeCustomer> response = customerService.List(); // can optionally pass count (defaults to 10) and offset

Updating a customer subscription

var myUpdatedSubscription = new StripeCustomerUpdateSubscriptionOptions()

// set these properties if using a card
myUpdatedSubscription.CardNumber = "4242424242424242";
myUpdatedSubscription.CardExpirationYear = "2012";
myUpdatedSubscription.CardExpirationMonth = "10";
myUpdatedSubscription.CardAddressCountry = "US";				// optional
myUpdatedSubscription.CardAddressLine1 = "24 Beef Flank St";	// optional
myUpdatedSubscription.CardAddressLine2 = "Apt 24";				// optional
myUpdatedSubscription.CardAddressState = "NC";					// optional
myUpdatedSubscription.CardAddressZip = "27617";					// optional
myUpdatedSubscription.CardName = "Joe Meatballs";				// optional
myUpdatedSubscription.CardCvc = "1223";							// optional

// set this property if using a token
myUpdatedSubscription.TokenId = *tokenId*;

myUpdatedSubscription.PlanId = *planId*;			
myUpdatedSubscription.CouponId = *couponId*;
myUpdatedSubscription.TrialEnd = DateTime.UtcNow.AddMonths(1);

var customerService = new StripeCustomerService();
StripeSubscription = customerService.UpdateSubscription(*customerId*, myUpdatedSubscription);

Canceling a customer subscription

var customerService = new StripeCustomerService();
StripeSubscription = customerService.CancelSubscription(*customerId*);	// you can optionally pass cancelAtPeriodEnd instead of immediately cancelling 

Charges

Creating a charge

When creating a charge you can use either a card, customer, or a token. Only one is allowed.

var myCharge = new StripeChargeCreateOptions();

// always set these properties
myCharge.AmountInCents = 5153;
myCharge.Currency = "usd";

// set this if you want to
myCharge.Description = "Charge it like it's hot";

// set these properties if using a card
myCharge.CardNumber = "4242424242424242";
myCharge.CardExpirationYear = "2012";
myCharge.CardExpirationMonth = "10";
myCharge.CardAddressCountry = "US";				// optional
myCharge.CardAddressLine1 = "24 Beef Flank St";	// optional
myCharge.CardAddressLine2 = "Apt 24";			// optional
myCharge.CardAddressState = "NC";				// optional
myCharge.CardAddressZip = "27617";				// optional
myCharge.CardName = "Joe Meatballs";			// optional
myCharge.CardCvc = "1223";						// optional

// set this property if using a customer
myCharge.CustomerId = *customerId*;

// set this property if using a token
myCharge.TokenId = *tokenId*;

var chargeService = new StripeChargeService();
StripeCharge stripeCharge = chargeService.Create(myCharge);

Retrieving a charge

var chargeService = new StripeChargeService();
StripeCharge stripeCharge = chargeService.Get(*chargeId*);

Refunding a charge

If you do not specify an amountInCents, the entire charge is refunded. The StripeCharge entity has properties for "Refunded" (bool) and RefundedAmountInCents.

var chargeService = new StripeChargeService();
StripeCharge stripeCharge = chargeService.Refund(*chargeId*, *amountInCents*);

List all charges

var chargeService = new StripeChargeService();
IEnumerable<StripeCharge> response = chargeService.List();	// can optionally pass count (defaults to 10), offset, and a customerId to get charges for a single customer

Invoices

Retrieving an invoice

var invoiceService = new StripeInvoiceService();
StripeInvoice response = invoiceService.Get(*invoiceId*);

Retrieving an upcoming invoice (for a single customer)

var invoiceService = new StripeInvoiceService();
StripeInvoice response = invoiceService.Upcoming(*customerId*);

List all invoices

var invoiceService = new StripeInvoiceService();
IEnumerable<StripeInvoice> response = invoiceService.List(); // can optionally pass count (defaults to 10), offset, and a customerid

Invoice Items

Creating an invoice item

Any invoice items you create for a customer will be added to their bill.

var myItem = new StripeInvoiceItemCreateOptions();
myItem.AmountInCents = 1000;		// all amounts on Stripe are in cents
myItem.Currency = "usd";			// "usd" only supported right now
myItem.CustomerId = *customerId*;
myItem.Description = "na";			// not required

var invoiceItemService = new StripeInvoiceItemService();
StripeInvoiceItem response = invoiceItemService.Create(myItem);

Retrieving an invoice item

var invoiceItemService = new StripeInvoiceItemService();
StripeInvoiceItem response = invoiceItemService.Get(*invoiceItemId*);

Updating an invoice item

var myUpdatedItem = new StripeInvoiceItemUpdateOptions();
myUpdatedItem.AmountInCents = 1010;		// all amounts on Stripe are in cents
myUpdatedItem.Currency = "usd";			// "usd" only supported right now
myUpdatedItem.Description = "test";		// not required

var invoiceItemService = new StripeInvoiceItemService();
StripeInvoiceItem response = invoiceItemService.Update(*invoiceItemId*, myUpdatedItem);

Deleting an invoice item

var invoiceItemService = new StripeInvoiceItemService();
invoiceItemService.Delete(*invoiceItemId*);

List all invoice items

var invoiceItemService = new StripeInvoiceItemService();				
IEnumerable<StripeInvoiceItem> response = invoiceItemService.List(); // can optionally pass count (defaults to 10), offset, and a customerid

Events

Stripe sends Events (or webhooks) whenever an associated action occurs. The list of events Stripe sends is documented here: https://stripe.com/docs/api#event_types

Receiving events from Stripe

1. In your application, create a handler that looks something like the below:

   namespace TheBestApplicationEverCreated { public class StripeHandler : IHttpHandler { public bool IsReusable { get { return true; } }

    	public void ProcessRequest(HttpContext context)
    	{
    		var json = new StreamReader(context.Request.InputStream).ReadToEnd();
   
    		var stripeEvent = StripeEventUtility.ParseEvent(json);
    	}
    }
   

   }

2. Create a StripeHandler.ashx in the root of your website (or wherever) that looks like this:

   <%@ WebHandler Language="C#" Class="StripeHandler" CodeBehind="StripeHandler.cs" %>

3. Login to Stripe and go to Account Settings, webhooks - from here, you can setup the url that points to your StripeHandler.ashx for testing.

Whenever an Event is received, StripeEventUtility.ParseEvent(json) will convert the response into a StripeEvent object.

Retrieving an event

If you have the id and you want to retrieve the event

var eventService = new StripeEventService();
StripeEvent response = eventService.Get(*eventId*)

List all events

You can list events in the same way everything else works in Stripe.net.

var eventService = new StripeEventService();
IEnumerable<StripeEvent> response = eventService.List(); // can optionally pass count (defaults to 10), offset, and StripeEventSearchOptions

You can also optionally pass a StripeSearchEventOptions which supports a specific Created timestamp, LessThan, LessThanOrEqualTo, GreaterThan, or GreaterThanOrEqualTo.

var eventService = new StripeEventService();

var eventSearchOptions = new StripeEventSearchOptions();

// created will match on an exact date time
eventSearchOptions.Created = DateTime.UtcNow; 

// or you could do something like
eventSearchOptions.LessThanOrEqualTo = DateTime.UtcNow;
eventSearchOptions.GreaterThanOrEqualTo = DateTime.UtcNow.AddMonths(-1);

IEnumerable<StripeEvent> response = eventService.List(10, 0, eventSearchOptions);

Errors

Any errors that occur on any of the services will throw a StripeException with the message returned from Stripe. It is a good idea to run your service calls in a try and catch StripeException.

The StripeException contains and HttpStatusCode and a StripeError entity. The StripeError entity contains the type, message, code and param. For more infomation, review the Errors section of stripe here: https://stripe.com/docs/api#errors
