Create an order using the Orders API

I feel so frustrated.
So, the workflow is this: create order, pay the order and fulfill the order all in one request.
The order id is VeHsLgVkNsOy07I51kEMS0w553TZY and still not showing, all responses are 200 on API logs, and no errors displayed on my debugging . Not sure what should I do, I feel like giving up on this, was trying to get a demo done but looks like is not worth it. I am sorry saying this, but this is how I feel.
