Webhooks and command line together?

Yes indeed I was trying that. The problem is I can not use GET “http://…/follows?first=1”. It gives error.

Code:
curl -X GET https://api.twitch.tv/helix/users/follows?first=1&to_id=user_id -H Client-ID:client_id -s

Result:
{“error”:“Unauthorized”,“status”:401,“message”:“Must provide a valid Client-ID or OAuth token”}‘firzst’ is not recognized as an internal or external command,
operable program or batch file.

When I put first parameter I get this result. But If I remove it I get normal result.
