I am working on getting all orders from amazon and displaying them on my site.
I just want to get the user's comments that are placed by customers against their order.
I was looking at the Amazon MWS documentation, but didn't find anything. I also tried to search it on google but nothing was found.
Is it possible to get comments on orders?
If so, then how?
I assume that you're talking about Amazon's Buyer-Seller Messaging Service. I've looked around and there does not seem any API to access that information. But you can relay those mails to a regular email client (which might be integrated into your web app through POP3 or IMAP). Your responses (sent through SMTP) will appear in Seller Central just like manually entered messages.
