uninitialized constant ChargesController::CONNECTED_STRIPE_ACCOUNT_ID

Question

Im using Stripe Connect Standalone for my application. So far the users can successfully connect their stripe account, and payments are coming through into my stripe account. The problem is that I need the users to be able to pay each other, and I retain the application fee.

At the moment, all payments simply come into my (the platforms) account, no application fee is taken, and the end user does not receive any money. after I searched for solutions, I added a stripe header to my charges controller, and used the charge method as displayed on Stripes docs. Once I submit the credit card form, I receive this error:

uninitialized constant ChargesController::CONNECTED_STRIPE_ACCOUNT_ID

this is in response to this line in my charges controller:

Stripe::Account.retrieve(CONNECTED_STRIPE_ACCOUNT_ID)

Here is my charges_controller.rb:

class ChargesController < ApplicationController

    def new
    end

def create
Stripe.api_key = "sk_test_1q2w3e4r5t6y...."

Stripe::Account.retrieve(CONNECTED_STRIPE_ACCOUNT_ID)

token = params[:stripeToken]

# Create a customer
Stripe::Customer.create(
  {:description => "[email protected]"},
  {:stripe_account => CONNECTED_STRIPE_ACCOUNT_ID}
)
# Create a Charge:
charge = Stripe::Charge.create({
  :amount => 1000,
  :currency => "cad",
  :source => token,
  :application_fee => 200 # amount in cents
}, :stripe_account => "{CONNECTED_STRIPE_ACCOUNT_ID}")

rescue Stripe::CardError => e
  flash[:error] = e.message
  redirect_to new_charge_path
end
end

initializers/stripe.rb

Rails.configuration.stripe = {
  :publishable_key => ENV['PUBLISHABLE_KEY'],
  :secret_key      => ENV['STRIPE_SECRET_KEY'],
  :stripe_account => ENV['CONNECTED_STRIPE_ACCOUNT_ID']
}
Stripe.api_key = Rails.configuration.stripe[:secret_key]

I'm new to Stripe Connect, and have been stuck on this part for a while. Driving me crazy. I have a "Pay now" button on the users profiles which should allow "User A" to pay "User B", while sending me an application fee. How do I fix this error? Is this the main issue in my payment flow (allowing users to pay each other via a button in their profile)?

UPDATE:

CONNECTED_STRIPE_ACCOUNT_ID hasn't been initialized, because it must be replaced with the connected users stripe_user_id. In my database this is saved as "uid". So now the issue is calling it into my application.

UPDATE 2:

When a user connects, their publishable key, and stripe user Id (uid in my db) are saved to my database. looks like this:

name: "Testguy", publishable_key: "pk_test_6IgEWlj4y##########", provider: "stripe_connect", uid: "acct_19l9#########", access_code: "sk_test_vldP#########">]>

now, how do I call their user ID in my application?

Stripe::Account.retrieve(UID)

gets the uninitialized error

uninitialized constant ChargesController::UID

Answer 1

You need to replace CONNECTED_STRIPE_ACCOUNT_ID by the ID of the connected account. Account IDs are strings that start with "acct_" followed by random alphanumeric characters.

When an account connects to your platform's account using the OAuth flow, you get its account ID in the last step of the flow, in the stripe_user_id field. You should then save this ID in your database.

You can then use the ID to process charges or issue any API request on behalf of this account, using the Stripe-Account header.
