The whole conversion seems to be unnecessary to me. Why not unify the API and frontend? The frontend should just use the values that the backend expects. And you are free to adjust the backend for the frontend needs.

[bjoernricks]

Should not be send via the api. At least not as methodData. We need to think about the api changes for the content composer sometime in future.

[bjoernricks]

Am really not satisfied with the alert handling and the API but we leave it as it is atm.
