Question about channel.ad_break.begin authorization

API
1

Hi there,
I’m trying to listen to this eventsub event, but no luck.

I’m using app access token, and I added the scope channel:read:ads.
I tried to subscribe to it in two different format.

{
type : ‘channel.ad_break.begin’,
version : 1,
condition : {
broadcaster_user_id : Deno.env.get(‘BROADCASTER_ID’)!
}
}

{
type : ‘channel.ad_break.begin’,
version : 1,
condition : {
broadcaster_user_id : Deno.env.get(‘BROADCASTER_ID’)!,
moderator_user_id : Deno.env.get(‘BOT_ID’)!
}
}

But in both cases I get 403 error with this message subscription missing proper authorization.

The goal is that my webhook that my own chatbot listens to, catches the ad breaks run on my channel.

What can I do so it could work?

So for Conduits or webhooks (webhooks in your case here)

You need PRIOR Auth from the broadcaster

You need to do user auth with the scope (channel:read:ads) from the broadcaster_user_id in the condition.

Then ignore that token (or store it for other use if it has useful other scopes on it)

Generate app access token with no scopes. And away you go.

This type doesn’t support a moderator_user_id in the condition and/or using auth/permission from a moderator. It has to be the broadcaster

For future ref: App Access Tokens cannot have scopes.
They will inherit the permissions of prior authentication from the users that auth to the ClientID.

In Summary the steps are:

  • Get a User Token from the broadcaster with the scope channel:read:ads
  • After that authentication is complete, create an App Access Token (or use an existing one for the same ClientID you user token’ed with)
  • Create a subscription request

And unless noted with the presence of a moderator_id in the condition for any type/topic on a webhook that is scoped this model applies. (chat types are different but we’ll only discuss general types/topics here)

Thanks.
That made much more sense. :slight_smile:
