You can do it by creating the discount first, and then adding it to the coupon entity. You can do this using an API route by first getting the discount data from the request, then making a new discount entity from it like so:

createDiscount(req, res, { table: 'discount' }).then(async discountData => { const couponData = await createCoupon(req, res, { table: 'coupon', discountId: discountData.id }); return couponData; });```
