问题
For consumable products, use consumeAsync(), found in the client API.
For products that aren't consumed, use acknowledgePurchase(), found in the client API.
A new acknowledge() method is also available in the server API.
After purchase the consumable product, is there any way can acknowledge the purchase in our backend side to allow second purchase?

You can use similar url which is used for server-side verification of an in-app purchase to acknowledge an in-app purchase. Its a POST method instead of a GET we use for verification. And you need to add acknowledge at the end.
