We have notifications that apply to both Sellers and Buyers and the recipient parameter indicates whether you are the buyer or the seller for the given order.
If your server does not respond at all or responds with a non-successful error code we will reattempt the notification 10, 120, 600, and 3600 seconds later. If there still has not been a successful response no more attempts will be made.
