Create multiple rewards with single request

According to api docs, creating custom rewards endpoint takes object value, but return rewards as array so it looks like I can create multiple rewards and get them all as array. But i cant find any way do to this. Is it possible?

It just returns a matching result to the list endpoint. Instead of changing from an array to just the object it keeps a consistent result. Same thing as the webhooks, it sends an array value even though it’ll only ever be one object in the array.

You can only create one reward at a time. For clarity.
