My application called AddItem, but it never received a response. How do I know if the item was added successfully or not?

Your application should pass a unique # (GUID) into the UUID argument of AddItem. If for any reason a response is not received, your application may retry the request. If the item had previously been added, then your application will receive an XML error indicating this condition.

Here is a sample request section with the UUID:

<?xml version="1.0" encoding="utf-8"?>
<AddItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<Description>item description.</Description>

Here is the error message in the response if the item is already listed with the UUID:

<ShortMessage>Duplicate UUID used.</ShortMessage>
<LongMessage>The specified UUID has already been used; ListedByRequestAppId=1, item ID=4503632367.</LongMessage>
<ErrorParameters ParamID="0">
<ErrorParameters ParamID="1">
