After a while I found out that there are a couple of existing solutions that I was not aware of. For example servant-queryparam-core
Servant combinator to parse query params as Haskell record.
Example:
data User = User {name :: String, surname :: String}
deriving (Generic, Show, Eq)
type TestAPI = "users" :> QueryParamsRecord User :> Post '[JSON] NoContent
Derive Generic for your record to use it.
HasLink currently does not actually add params, because of
issue.
