Hi @ilkosta
Which version of Metabase?
When playing around with the API, I would highly recommend that you start by using the regular Metabase interface, while having your browser developer Network-tab open. It’s definitely the easiest way to learn the API.
The parameters is a little special and needs to be serialized - see the API docs:
-d 'parameters=%5B%7B%22type%22%3A%22category%22%2C%22target%22%3A%5B%22variable%22%2C%5B%22template-tag%22%2C%22cf%22%5D%5D%2C%22value%22%3A%22foo%22%7D%5D'
