Was this a scheduled API change? I hadn’t seen a notice about it, and from talking to another third party Twitch library developer, they also didn’t expect this change.
Helix has always used duplicate params rather than CSV’s
This endpoint (Get All Stream Tags) never documented the use of a CSV
An ID that identifies a specific tag to return. Include the query parameter for each tag you want returned. For example, tag_id=123&tag_id=456. You may specify a maximum of 100 IDs.
