Platform notifications are triggered by events on eBay marketplaces, such as the ending of a listing or the creation of a transaction. Notifications are Simple Object Access Protocol (SOAP) messages about events on eBay marketplaces that are sent to subscribing applications.
Subscribing to platform notifications is done using SetNotificationPreferences. Once subscribed, the Platform Notifications are then asynchronously pushed to the delivery locations (i.e., URLs or email addresses,) that have been specified.
Calling GetNotificationPreferences returns information about notification events to which the eBay user is subscribed.
Calling GetNotificationsUsage returns detailed information about the notifications events that have been sent to the eBay user.
For complete information about using Platform Notifications, refer to the Platform Notifications Guide.
