Unable to find the APIs for Shipping and Refund

Hi Team,

We are unable to find the APIs for the shipping and refund with item details.

Even we are not able to create the delivery/partial delivery from the UI, we are only able to change the status. Could you please provide the exact steps to create shipping/partial shipping/refund/partial refund based on that we can select the quantity while shipping.

Thanks in advance.

Regards,
M. Asharaf
