There is no way I'm giving out my Amazon creds which also house AWS, Amazon Payments, Amazon Sellercentral, etc...
Much more cumbersome for users but I see a report option where you can generate .csv's of every item you ordered, maybe those could be uploaded to your service, but unfortunately if I can't use this service without handing over my creds I'm not going to use it.
