How can I simulate a refund of an in app purchase in the sandbox environment?

Question

My application implements in app purchase of non-renewable and renewable subscriptions. I know I can use https://sandbox.itunes.apple.com/verifyReceipt to verify the validity of a receipt for one of these subscriptions, but is it possible to simulate the refund of a purchase in the sandbox environment?

If so, how is this done?

Answer 1

Refunds aren't technically possible through Apple. If your customer contacts Apple for a refund, they'll typically redirect the customer to you to handle this.

If you really want to offer refunds of your products, you'll have to keep a database somewhere of purchases and track which refunds you have given and to whom.
