📘
API Behaviour:

Above payload contains the complete details of API payload for coupon redemption.

Coupon details are mandatory and primary fields in redemption API call

You have to pass the query parameter as redeem or revert to let Rehook know that whether coupon is to be redeemed or reverted.

Coupon cannot be redeemed for non logged in users. you have to pass the source id mandatory in all redeem or revert API call, otherwise API will return error message.

You have to share the mandatory fields of order and item object in redeem or revert API call to validate the coupon conditions if you have not validated it using validate coupon API. this works as a fall mechanism to avoid redeeming inapplicable coupon codes.
