This post says the Company Name field was supposed to be added to Accept Payment form in May of 2018 but its not showing on ours?
I also tried sending the Company Name in the BillTo Transaction Request and it still doesnt get saved in the Company field when the transacation is processed.
I do have the same issue (well, my client has).
My client is putting pressure on me saying I am the one not correctly implementing your API.
Please, add the Company Name field on the Accept Hosted Payment Form as soon as possible.
AND/OR, fill the transaction details with information sent in <billTo><company>.
