Why does GetSellerPayments not return any response for some users?
GetSellerPayments has some inherent limitations and does not work very well for large volume Half.com sellers. It takes a fairly long time to return a response and in some cases the response times out even though you set a very high timeout value on the client side. The best alternative to making this call is to use FileExchange and use the scheduled reports to get the Payment information. You can get more information about FileExchange from the Instructions and Resources page.
