How to register domain using OVH API

Question

I have problem with registering a domain using API OVH. In first step I create cart with:
POST /order/cart
Then I check if domain is available:
GET /order/cart/{cartId}/domain
If it is, than I add it to cart with:
POST /order/cart/{cartId}/domain
And I dont know what to do next? How to confirm and order a cart? Which method I should use?

Or maybe there is another way to register domain using diffrent methods? Thanks for any help.

It's a bit late but I'm starting to search the information because I want to implement it and looks like you have to call to the configuration endpoint (POST /order/cart/{cartId}/item/{itemId}/configuration) and then perform the checkout (POST /order/cart/{cartId}/checkout) as far as I can see.
