I'm trying to add UPS Surepost into the UPS shipping options but have found scant info about it. As far as I can tell, there is no API info although it's supposed to work with their standard API using service code 93 for packages over 1 pound or 92 for packages under a pound. But I haven't gotten it to work. I tried with the stock UPS module and in the Advanced Shipper module which has a decent amount of the USP module code in it. Ultimately I need it to work in AS but if anyone has it working in the stock UPS module I can probably figure out how to integrate it into AS.
