Create Playlist with Grafana API using curl

Hello,
can someone help me to create a playlist using grafana API?
I tried this but it wont work.

curl --insecure -X PUT -H "Content-type: application/json" -d '{
         "name": "my playlist",
         "interval": "5m",
         "items": [
           {
             "type": "test-1",
             "value": "3",
             "order": 1,
             "title":"my third dasboard"
           },
           {
             "type": "test-2",
             "value": "myTag",
             "order": 2,
             "title":"my other dasboard"
           }
         ]
       }' 'http://admin:admin@localhost:8001/api/playlists/1'
    ->{"message":"Playlist not found"}

I looked at the docs and couldn’t find what I´m doing wrong :frowning:

Thanks for help
