Is it possible to assign a category to a topic with the Write API?

I don't see this feature in the API endpoints. Am I missing something?

What do you mean, when you create the topic or when you want to move it?

Thanks @Giggiux. I don't see how you assign a category to a topic, either when you create the topic or at a later stage.
