Embedding Video by video id return 400 and cors problem

[BarryCarlyon]

user_name and channel name are two names for the same thing.

A user_name has a user_id

Use the user_name in the channel embed to embed the stream.

@Roman_Tatarinov

user_name string Login name corresponding to user_id .

Yes

@Roman_Tatarinov

Then user_id it a user_name too

No they cannot be used interchangably

@Roman_Tatarinov

And is it channel name??

user_name is the channel_name
user_id is the user_id
