      summary: Create Invoice
      description: '**Purpose:**


        Captures against an order. This can be done against part of the authorised order amount (partial capture) or its entire amount (full capture).


        For partial captures, please submit each as a separate request specifying the amount until the full amount of the associated Order is reached.


        **Preconditions:**


        - `id`: The unique identifier of the order

        - Order with `id` has a sufficient unshipped `amount` (not lower than the `amount` provided to be captured).

        - Invoice Number present as `external_code`

        - Invoice present and reachable for download at `invoice_url`


        **Success:**


        - Response Code: `HTTP 201`

        - Response body: ''uuid` -> unique identifier of the capture


        **Attention:**


        - Only one order `id` can be provided per request.

        - Don’t submit a negative `amount` value.

        - The referenced order will change its state to `shipped` if the full `amount` is captured and `partially_shipped` for a capture amount lower then the order amount.

        - Capturing an order that is already partially shipped with an amount equal to the remaining amount will change the state of the order from `partially_shipped` to `shipped`.'
