New entry Call via API not working

[ITI]

We can add Accounts, Contacts ... everything else via the API.
But when we want to add an Call via the API we get unknown error.

This is not working for a call

$response = $client->request('POST', 'Call', [
'name' => 'Test'
]);

This works for example a contact

$response = $client->request('POST', ‘Contact', [
'firstName' => 'Test'
]);

Hopefully someone can help me.
