No idea, this is the third party developers support room, we don’t know too much about what the first party website supports or doesn’t support.
Use the API to achieve this
or use EventSub to be notified in real time.
In my opinion: this is not a permitted under the rules and not a thing I would advise the broadcasters I work with to support.
It’s not free if you are using Channel Points to enter with.
As Points are transactioned for a entry to a giveaway.
Since you can earn CP’s from Giftin Subs for example
Additionally Channel Points are not available with in all countries, so you would disallow entry to some users.
This may in fact not be allowed under the ROC/Acceptable Use Policy

A “free giveaway” may be in violation of
- When creating Points redemption opportunities, be sure to follow all applicable tax laws in your jurisdiction. Compliance with local tax laws is your responsibility and Twitch bears no responsibility for ensuring your compliance with these laws.
or
- Do not create Points redemption opportunities that constitute gambling.
or the final point
- Do not use Points in connection with any activity prohibited by Twitch’s Terms of Service, Twitch’s Terms of Sale, Twitch’s Community Guidelines, or Twitch’s Developer Services Agreement.
So I don’t not believe offering a Giveaway via Channel Points is allowed and generally is not a good idea, legally speaking.
PLEASE NOTE THIS IS NOT LEGAL ADVICE AND YOU SHOULD CONSULT A LAWYER FOR LEGAL MATTERS.
