Creating Stripe customer from Stripe Token using .Net client library & Stripe.js

Question

I have a screen in my ASP.NET MVC web application in which I ask the user for their credit card information. They type it in.

Adhering to PCI guidelines, I am using Stripe.js to send this credit card information to stripe and get back a stripe token.

I then post this stripe token to my ASP.NET MVC application. In the application, I would like to create a customer. I would not like to charge the customer just now. I simply want to create a customer so I can charge them later using their Stripe customerId.

The documentation provided here makes it look simple. However, the client library that I am using (Stripe NuGet package version 1.12.0) does not offer the StripeCustomerCreateOptions class and many other classes mentioned in that document.

Instead, it has these two methods that help you create a customer:

public StripeObject CreateCustomer(ICreditCard card = null, 
             string coupon = null, 
             string email = null, 
             string description = null, 
             string plan = null, 
             DateTimeOffset? trialEnd = default(DateTimeOffset?));

public StripeObject CreateCustomerToken(string customerId);

As you can see, none of the methods are of any help to me. The first one requires the server to pass credit card information, which I am not doing as it is against PCI guidelines.

The second one assumes that you already have a customer and you want a token for the customer to use someplace else.

How do I create a customer from within my ASP.NET MVC application if I already have a credit card token for him that I got from Stripe.js?

According to this, you should be able to pass the token ID in the card parameter of the CreateCustomer() method. — Ywain
@Ywain You are right. I looked things up in reflector. Turns out that there is a class named CreditCardToken that implements the ICreditCard interface and so it can be passed in place of the card parameter. The CreditCardToken class represents such a token and can be instantiated by giving to its ctor the string token you received from Stripe. I was able to do this immediately after writing the question. Just didn't have the time to update this question with an answer. If you will, I will mark it as the right one. — Water Cooler v2

You can construct a CreditCardToken from a token ID (see here: https://github.com/nberardi/stripe-dotnet/blob/master/src/CreditCardToken.cs#L8).

As CreditCardToken implements ICreditCard, you can then use it as the card parameter in the CreateCustomer() method.
