Stripe error: "The card object must have a value for 'number'" when creating a Customer

Question

I am using Stripe's ruby gem to (try to) perform two steps:

1. Collect a card using Stripe's "Checkout" form
2. Create a Customer using the token provided by the redirect from the form submission

The latter of these steps raises a Stripe::CardError whose message is:

The card object must have a value for 'number'

The API doc describes the process: https://stripe.com/docs/tutorials/subscriptions#subscribing-a-customer-to-a-plan

My code (a Rails controller action)

def receive_redirect
    customer = Stripe::Customer.create(
      plan: "stripe_plan_name",
      card: params[:stripeToken]
    )
end

params[:stripeToken] looks like this:

{"id"=>"tok_1044TY4GgNdNSosPXdAmIZdt", "livemode"=>"false", "created"=>"1400620581", "used"=>"false", "object"=>"token", "type"=>"card", "card"=>{"id"=>"card_1044TY4GgNdNSosPuDSuygow", "object"=>"card", "last4"=>"9424", "type"=>"Discover", "exp_month"=>"9", "exp_year"=>"2014", "fingerprint"=>"Lz5ASwlmyseG0gYo", "customer"=>"", "country"=>"US", "name"=>"[email protected]", "address_line1"=>"", "address_line2"=>"", "address_city"=>"", "address_state"=>"", "address_zip"=>"", "address_country"=>""}, "email"=>"<my_email>@<my_host>"}

...As you can see, they don't give me a number, so what am I to do?

Answer 1

The value you should be setting card: to is just the id of the token and not the entire object you are passing right now. Something like this (my ruby is a bit rusty):

card: params[:stripeToken][:id]

You can see an example of valid inputs to Customer.create in the Stripe API Docs.
