I was going through the various limits on the minimum payment amount. This page helped me a lot in understanding the various bounds, but then I saw the Working with monetary amounts page and in there under the EXPECTED_INTERGER error code section, it is mentioned that the regions like Australia, Japan & UK must have a minimum amount field of 100 cents.
Whereas on the earlier page, the Australian region is having a minimum payment of $1 (100 cents), and for other methods, the minimum is even 0/1 cents. So, what exactly is being specified on the latter page?
