Need help: do I have to subscribe to an API?

[0zxfl37]

I aim to create an application that provides users with the most recent information about winning products. I have it coded. However, I can't see where I can subscribe or whatever there is to use the API. I came across the Finding API but there wasn't anything on there I was redirected to the Marketplace Insights API and there I also couldn't find where to get it. Can someone tell me where to get it and is it free?

Hi @0zxfl37,

You can use the SetNotificationPreferences to subscribe to the platform notifications events like:

- EndOfAuction (is sent to all subscribed bidders of an auction item and to the subscribed seller of the auction item as soon as the auction listing ends with or without a winning bidder)

- AuctionCheckoutComplete ( is sent to the subscribed seller when the winning bidder or buyer has paid for the auction or fixed-price item and completed the checkout process)

- ItemUnsold (is sent to a subscribed seller when an auction listing ends with no winning bidder or when a fixed-price listing ends with no sale(s).)

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.
