Figured it out... You have to set "amountSpecified" = true Example: var
sub = new ARBSubscriptionType(); sub.amount = (decimal) 1.23;
sub.amountSpecified = true;
I am having the same issue. I can create, delete, and even update most
properties of the subscription... but not the amount... The response
from the test server says successful, but the amount never changes. Can
anyone shed some light on this issue? ...
