There is no API methods for deleting a Clip
Please provide a method
There is a way to delete Clips as a Streamer using GraphQL.
but according to twitch you are not permitted to use that existing API https://discuss.dev.twitch.tv/t/is-it-legal-to-use-https-gql-twitch-tv-gql-endpoint/21811
So this is getting my upvote and in addition I'd ask for a role based implementation, so moderators/editors can help the streamers to delete clips (that might violate TOS as a good example)
This is an essential need for developers to build tools to help broadcasters manage clips during the increase of DMCA requests
