Unable to start a commercial through Helix as channel's editor

[zneix]

Brief description Upon trying to start a commercial on the channel where I'm an editor I get the following response: {"error":"Bad Request","status":400,"message":"broadcaster_id and user_id do not match."}

How to reproduce Make the following call for the channel where you're an editor while it's live curl -s -H "Authorization: Bearer foobar" -H "Client-ID: foobarbaz" -H "Content-Type: application/json" -X POST "https://api.twitch.tv/helix/channels/commercial" -d '{"broadcaster_id": "97916945", "length": 30}' | jq

Expected behavior I expect being able to start a commercial in a channel that I am editor in, so most likely a 200 OK.

Screenshots N/A

Additional context or questions I called the endpoint first with a token that has only channel_commercial scope and then with another that had both channel_commercial and channel:edit:commercial. {"error":"Unauthorized","status":401,"message":"Missing scope: channel:edit:commercial or channel_commercial"}

I tried tokens with different scopes:

1. channel_commercial
2. channel:edit:commercial
3. channel_commercial and channel:edit:commercial

and got the same response on each of these.

The API doesn't support this.

And what you refer to is undocumented kraken behaviour (editor can start ads via the API)

This is a feature request not a bug. So should be on uservoice. (You mis wrote your expected behaviour as thats what the API does)

I expect being able to start a commercial in a channel that I am broadcaster in, so most likely a 200 OK.

That should be

right?

And a uservoice does exist - https://twitch.uservoice.com/forums/310213-developers/suggestions/44183481-helix-start-commercial-endpoint-should-be-usable

it kinda looks like you have reported two different issues here and I know helix doesn't support an editors token only the broadcasters tokens for creating adverts

yes, my bad, I meant to write editor instead of broadcaster. edited original post. sorry for confusion

Then yeah this uservoice

Superseeds this, as it is "not a bug".

As the old API never actually documented that an editor token works. And Helix doesn't support it at all, so the documentation is correct.
