I want to develop an app that allows the users of the app (sellers on Amazon), to send me a notification when they receive an order on Amazon (a notification containing informations about the order).
Is it possible?
Maybe only the seller can receive notifications about his account.
I think, if it's possible, I need a MWS and a AWS account.
In the documentation of MWS (https://docs.developer.amazonservices.com/en_US/notifications/Notifications_Overview.html), there is:
The Amazon MWS push notifications enable you to receive information that is relevant to your business with Amazon without having to poll the Amazon MWS service. Instead, the information is sent directly to you when an event occurs to which you are subscribed. For more information about how to subscribe to receive notifications, see Subscriptions Overview in the Amazon MWS Subscriptions API section reference.
Then, in the 'Subscriptions API' section:
The Amazon MWS Subscriptions API section enables you to subscribe to receive notifications that are relevant to your business with Amazon. With the operations in the Subscriptions API section, you can register to receive important information from Amazon without having to poll the Amazon MWS service. Instead, the information is sent directly to you when an event occurs to which you are subscribed.
To receive notifications, you must first create and register a Destination, such as an Amazon Simple Queue Service (Amazon SQS) queue. Then, you create a Subscription for the NotificationType that you want to receive, such as a notification when another Seller has changed their offer for an item that you also sell. Finally, verify that Amazon is able to send notifications to your Destination by calling the SendTestNotificationToDestination operation.
