Sandbox API Explorer GetNotificationsSettings error

[dude.t54]

Am working on subscribing to notifications and using the API Explorer to test API calls. When testing the Trading API at https://developer.ebay.com/my/api_test_tool?index=0&api=trading&call=GetNotificationPreferences&vari... any api selected seems to work just fine. However, when testing the two APIs I need for event subscription, SetNotificationPreferences and GetNotificationPreference, they both fail and have been failing for several days now:

<?xml version="1.0" encoding="UTF-8" ?>
<GetNotificationPreferencesResponse 
  xmlns="urnapis:eBLBaseComponents">
  <Timestamp>2024-10-26 00:34:14</Timestamp>
  <Ack>Failure</Ack>
  <Errors>
    <ShortMessage>Internal error to the application.</ShortMessage>
    <LongMessage>Internal error to the application.</LongMessage>
    <ErrorCode>10007</ErrorCode>
    <SeverityCode>Error</SeverityCode>
    <ErrorClassification>SystemError</ErrorClassification>
  </Errors>
  <Version>967</Version>
  <Build>19146596</Build>
</GetNotificationPreferencesResponse>

The headers are as auto-filled by eBay.

Request body only thing updated is preference level.

<?xml version="1.0" encoding="utf-8"?>
<GetNotificationPreferencesRequest xmlns="urnapis:eBLBaseComponents">    
	<ErrorLanguage>en_US</ErrorLanguage>
	<WarningLevel>High</WarningLevel>
     <!-- Set the Preference Level to Application, User, Event, or UserData -->
<PreferenceLevel>Event</PreferenceLevel>
</GetNotificationPreferencesRequest>

I see the same problem all notification endpoints in sandbox seem to fail?

Hi @lizardpeoplearetakingover,

When executing the GetNotificationsUsage call you need to specify the ItemID in the request as it is a required field for the call.
