Unable to Access Webhooks API for Draft HubSpot App

Dear HubSpot Support Team,

I have created a HubSpot application and assigned the required permissions. However, when I try to access the following endpoint using my access token and app ID:

GET https://api.hubapi.com/webhooks/v3/{APP_ID}/settings

I receive the following error response:

Error Message: Authentication credentials not found.
This API supports OAuth 2.0 authentication and you can find more details at
category: “INVALID_AUTHENTICATION”

Could you please clarify if it is possible to access all webhooks-related API calls without publishing the app? Currently, my application is in Draft mode, and I would like to confirm if this limitation is expected or if I may be missing a configuration step.

Thanks & Regards
