This is a "Hail Mary" pass.

does anyone know where i can find a list of field elements which amazon provides in the "inbound order" request (assuming i am phrasing that correctly). so far i have not been able to locate it in their documentation.

my application makes this request and we populate our order entry module with these orders. it has done this now for several if not many years. My problem is that suddenly two of the field elements (SHIPNAME and SADDRESS1) are now arriving "blank".
thus the order arrives in our system in a state where it is not possible to fulfill the order.

The back story is that we elected to go with a 3rd party "marketing channel" provider which proved disastrous.
some time having elapsed, we dumped them and reactivated our proprietary process.

in the interim, it appears that amazon has made a change ergo the blank field elements.
so i am hoping (is that really a strategy?) that they have alternate field elements that i am not aware of that i may substitute for the blank elements.

thanks in advance for any pearls...
