Possible in v2 using custom operations and documented: https://github.com/api-platform/docs/blob/master/core/operations.md

I am having problems with Embedabble, wich is not being deserialized.
Embedabble is common practice for those wich are trying to use the Value Objects into their domain.

I don't know if im doing somethig wrong... but im trying to solve it with a port deserialize listener

Closing, embedded are supported the last thing that needs fixing is in the documentation (#618)!
