If we submit different document sizes using the same account, do we need to specify the different sizes? How is this controlled?
The API doesn't currently support the specification of paper size.The paper_size profile element is not generally used within the system. For most of the document formats that we deal with, we use the guidelines within the documents themselves to control the resulting image size. So setting that value on a per-job basis would actually have very little effect on the resulting faxes that you send out.
