Drive workflow via API

Hi,

Is it possible to drive a custom workflow for a Codyt project using the API?

My problem is that I want to have an extra task after the Review task only when the translation is for Japanesse. For the other languages I don't need that extra task.

I was thinking of doing this, using a webhook when the Review task is completed and then creating the extra task via API. But I have seen that the method to create tasks is only available to Standard projects.

How can I do that for Codyt projects?
