May i ask something, is consumable purchase type will receive event callback notification from App Store Server to Our Server? Notes: its comsumable type, not subscription and not auto renewal subscription. For example: User checkout an item (gems, diamond, or premium features) using in-app purchase After user click "Purchase" button, normally payment gateway sent callback to our server.... But if its not sent, then the flow just handled by frontend only? Thankyou

Is there any features in dashboard appstore connect to check or monitor if there is a callback event has been sent? Thankyou

Is comsumable purchase type will receive callback event during purchasing proccess? Maybe like flow below: User purchase premium features Store data into database callback url waiting for data from app store notification. If is not, then we only validate the purchase by frontend only? not server to server?

Hi, thankyou for answering, very hepful solution! AppStore Engineer says that non-consumeable purchases do not sent callback or events like another payment gateway. So this is unique and im new on it. I will consider to user IAPHUB then. Thankyou Marco!

Thankyou for your reply, that statement is very clear.
