Creates a new coupon.
The createCoupon() function returns a Promise that resolves to the new coupon when it is created.
When creating a coupon, the specification object must contain values for name, code, startTime, and either scope or minimumSubtotal. The exception is for a freeShipping coupon type, for which you cannot apply a scope and minimumSubtotal is optional.
The coupon scope defines the items a coupon applies to. A coupon can apply to all items in a specific Wix application, a group within the application, or a single item within a group. See the introduction for a table of currently supported coupon scopes.
The specification object must also contain a value for exactly 1 of the following coupon properties. This defines the coupon type.
