Warning
- A new order always answers status 0. It is never the final answer.
- A timeout or any HTTP error means you do not know yet. Treat it as 0.
- Get the final status from the webhook or Check a status — never by placing the order again.
- Only retry with a new
order_id, and only on status 2. - Sending the same
order_idtwice is safe: you get the first order back.
What each status means, and what to do: Order status.
