Hi,
I want to review some parameters in the ERP related to the customer before submitting the final order. It the parameters are not approved, the order must remain as a cart and display some additional information.
What is the most appropriate way to acheive this? I can't find a notification subscriber that lets me hook in on the correct spot, so I'm guessing I have to create a custom gateway provider for this (there's no other payment on the solution)?
BR.
Lars
