More info on tracking one-time charges

Hey!

I'm curious what the recommended way to handle one-time purchases through pay is. Specifically, I'm looking at Section 8 of the Stripe docs (https://github.com/pay-rails/pay/blob/main/docs/stripe/8_stripe_checkout.md#fulfilling-orders-after-checkout-completed) where there's some information on fulfilling orders after a checkout.

I'm struggling to figure out what should go in the # Handle fulfillment section of the given code example — 

Pay::Webhooks.delegator.subscribe "stripe.checkout.session.completed", FulfillCheckout.new
Pay::Webhooks.delegator.subscribe "stripe.checkout.session.async_payment_succeeded", FulfillCheckout.new

class FulfillCheckout
  def call(event)
    object = event.data.object

    return if object.payment_status != "paid"

    # Handle fulfillment
  end
end

I'm wondering if I should manually create a Pay::Subscription here to indicate that the User (who just purchased access or whatever) now has access to the product.

Does this seem right, or am I missing something? I'm wondering if there's a state on Pay::Customer I should set here instead; I've gone through the Pay::Customer code at https://github.com/pay-rails/pay/blob/main/app/models/pay/customer.rb but nothing stood out to me.

Thanks!

Yeah, although webhooks aren't reliable so you could end up in a situation where the user is redirected before the fulfillment happens.

I also use the redirect_url from the checkout session to call Pay::Stripe::Subscription.sync_from_checkout_session to ensure that it's fulfilled even if webhooks are delayed. This is helpful as well that you don't need to have Stripe CLI running in development for basic checkout testing. The user isn't guaranteed to hit this URL I've noticed, so the combination of this and webhooks doing fulfillment should handle every situation.

We were just talking yesterday about introducing a Pay::Stripe.sync_from_checkout_session that can handle subscriptions or one-time payments to simplify the interface for users. Gonna hack on that today if I get a chance.
