Update Stripe's Customer Credit Card Information

Question

I finally figured out how to implement Stripes Monthly Billing using this tutorial. So far, A User can Create & Delete their Subscription with Stripe. But I am having trouble calling the hashes inside the API to have the User change his credit card information. Question: How do I call/pass the child parameters in the documentation to update the Credit Card Fields using the method I have created `update_card`? This is my Code with Comments: CONTROLLER ``` class SubscriptionsController < ApplicationController def update @subscription = current_user.subscription ### I use the method update_card to update the customer's card @subscription.update_card if @subscription.update_card redirect_to edit_subscription_path, :success => 'Updated Card.' else flash.alert = 'Unable to update card.' render :edit end end end ``` MODELS ``` class Subscription < ActiveRecord::Base attr_accessible :plan_id, :user_id, :email, :stripe_customer_token, :last_4_digits, :card_token, :card_name, :exp_month, :exp_y…

Accepted Answer

either you can create a new card and delete the old one that will make the new card default_card for that customer or you can also achieve it by updating the customer and passing card details as mentioned here(check card field and its child parameters) https://stripe.com/docs/api#update_customer

Edit:

Do it like this

```
require "stripe"
Stripe.api_key = "sk_test_BQokikJOvBiI2HlWgH4olfQ2"

token = Stripe::Token.create(
   :card => {
   :number => "4242424242424242",
   :exp_month => 1,
   :exp_year => 2015,
   :cvc => "314"
   },
)
cu = Stripe::Customer.retrieve("cus_3Ok02kebTNsPDJ")
cu.card = token.id
cu.save
```
