Hello @AtsukiSambo
A 404 Not Found error infers the request iself is invalid (IE, there is a fault with the request path / structure / parameter value etc). That error has nothing to do with whether or not the token or the user has the relevant scope or permissions; permissions faults cause 401 Unauthorized errors.
You need to provide a COMPLETE description of your problem, which includes how you’re making the request, the actual code of the request itself, what testing you’ve done with your API test tool etc, etc, etc.
Refer to the How to ask a good question thread for an overview of the minimum that’s expected.
