With PayPal "Transfer cart line items" set to Yes, is there a way to also transfer some of product attributes?
I've had a look at Paypal/Model/Api and Payment Details Item Type Fields, but Paypal extension's internal cart only seems to be storing only title, qty and amount.
I also tried to test with
paypal_prepare_line_items event. Interestingly enough, the whole thing would crash without an error each time I try to var_dump or in any way read content of $observer->getPaypalCart() in the observer method. I haven't been able to move from there.
I was wondering if anyone's had luck adding product attributes to Paypal line items.
