Unable to Add marketplace:write:event_subscription Scope for OAuth App

Hi Team,

I’m trying to create an event subscription using the following API:
https://api.zoom.us/v2/marketplace/app/event_subscription

I’m using an access token obtained through the OAuth flow, but I receive the following error:

Invalid access token, does not contain scopes: [marketplace:write:event_subscription]

I attempted to add the marketplace:write:event_subscription scope to my app, but I’m unable to find this scope listed in the available options for a user-managed OAuth app.

Interestingly, I am able to successfully create an event subscription using the same API when I use an access token generated via basic authentication (account-level app).

Could you please clarify the following:

  1. Is it possible to use the marketplace:write:event_subscription scope with a user-managed OAuth app?
  2. If yes, how can I add this scope to my app?
  3. If no, is dynamic event subscription creation only supported through account-level apps using basic authentication?
