When validating consumable item receipts on the server.

In swift, when I purchase a consumable item, it sends a receipt to the server for validation. In storekit, I know that it checks the purchase history of the consumable item on the server and then calls the finishtransaction() function inside the app.

So how can revenucat do this? When I use revenucat, I tried to check the purchase history on the server but there is no history. 

Please tell me how to do it.

Thanks.
