This was in the API newsletter:
"OAUTH callback category
You can subscribe to notifications on canceled OAuth connections using the new OAUTH callback category."
However, when i subscribe a NotificationFilterUrl for the OAUTH category, and i cancel my App Connection in the app, no notification is received at the endpoint.
(The MUTATION category filter works instantly, so my method of subscribing and my endpoint are ok.)
Is this supposed to work in the Sandbox?
Where are the API docs about this? doc.bunq.com has no mention of this new category.
