Look at the in_app field: The document says that:

in JSON file , The value of this key is in an array that contains all in-app purchase receipts. In the ASN.1 file, there are several fields in which all have 17 types, each of which has an in-app purchase receipt.

In many of my tests, the in_app list is the receipt information that I was sent to Apple's server. But what are the other two elements?

I send different receipts to verify, the other two elements are always the same.

Why is that so? help me!
