OutSystems is actively supporting integration of ODC and O11. Currently, the only way to consume logic from each other is to use a REST API. This is cumbersome and portentially unsafe. It would be much easier if the Platform allowed consuming Service Actions instead (which in essence are also REST methods, but easier to use).
So O11 logic could consume an ODC Service Action, and ODC logic could consume an O11 Service Action. This would greatly enhance easy operability, and be secure out of the box.
