Topic: checkout sequence - payment
When is the checkout sequence is the optimal time for saving the order?
I have a:
a. cart and cart item model
b. a customers model and table
contained within these objects is all the necessary information to authorize the sale.
Is there any reason for not authorizing a sale ....just before all of these objects are saved into a customer:order:lineItem form in the respective tables.
I am asking this question because it seems cleaner and more straight forward to send information to a payment gateway before it is saved due to AVS errors.
I'm thinking that the response from the gateway would determines the conditional next step.
if the transaction passes
save the customer, order and flush the cart
proceed to 'thanks' and fulfillment
redirect to the customer/cart info for address AVS errors and
let the customer re-submit.
Is there any vulnerability that I don't 'get'.
