Cashback coupons rest api

Hi There,

I am trying to make an app from my WordPress website using REST apis. While placing an order through REST api, the Woocommerce coupon attribute [coupon_lines] is working fine with coupon codes of discount coupons. But, the coupon codes that are marked as cashback are not working properly through REST api. The system is treating them as normal coupons rather than cashback coupons. The order is being placed with a discounted price. When the order is placed from website, the coupon code works fine as the system treats it as a cashback coupon.

What additional information must I pass to the system while placing the order through REST api so that the cashback coupon codes work as they do on the website?
