Get Returnable Lines
For a delivered order, list which lines can still be returned and the maximum returnable quantity for each (ordered/fulfilled minus already-returned), plus ineligible lines with a reason (`not_delivered`, `window_expired`, `already_returned`). Returns 404 if the order is not on the active location.
Request a Return
Request a return for selected lines of a delivered order. Each line's quantity is validated against the returnable computation (over-quantity or ineligible lines are rejected). Creates an RMA in the requested state for merchant approval.
List Returns
List the active account's returns (RMAs).
Get Return
