How to remove notification setting

Hi there, I check the settings for one of my customers (seller id 1122731) and I found thet there are 15607 notification settings of the same type (Curl_Default) and all with the same URL (that's the correct one).
I did not find any othe notification setting, but the notification works fine.
I need to add a new setting to a different URL but I would like to remove the old ones.
I did not find any call to remove a setting,
Could someone remove all the setting, but the first one?
Thank you for your help
Daniele

Thank you Benjamin for the quick reply.
I run the getNotificationSettings and I've got the following return data
stdClass Object
(
[data] => Array
(
[0] => stdClass Object
(
[id_notification] =>
[id_user] =>
[channel] =>
[type] =>
[destination] =>
[active] =>
)

[1] => stdClass Object
(
[id_notification] =>
[id_user] =>
[channel] =>
[type] =>
[destination] =>
[active] =>
)

[2] => stdClass Object
(
[id_notification] =>
[id_user] =>
[channel] =>
[type] =>
[destination] =>
[active] =>
)

[3] => stdClass Object
(
[id_notification] =>
[id_user] =>
[channel] =>
[type] =>
[destination] =>
[active] =>
)

[4] => stdClass Object
(
[id_notification] =>
[id_user] =>
[channel] =>
[type] =>
[destination] =>
[active] =>
)

[5] => stdClass Object
(
[id_notification] =>
[id_user] =>
[channel] =>
[type] =>
[destination] =>
[active] =>
)

)

[status] => 1
[errorMsg] =>
[personal_reference] =>
)

Any Idea?
Thank you

The php code is quite simple:
$return = $DcSoapClient->getNotificationSettings($dctok);
echo "<pre>";
print_r($return);
echo "</pre>";

($dctok is the token returned by authenticateUser )

I wait for you to cjeck before setting the notification data.

Thank you

Thank you Benjamin,
unfortunately I developed tons of code based on SOAP APIs and the idea of moving to REST APIs is quite terrific

I made the test few seconds ago with the same results.

Now I'm going to set the other notification parameters.

Kind regards
Daniele
