Hi. I'm using the apple API to validate the originalTransactionId I'm getting from the client.
I also want to use the expireDate that comes from the last transaction. Can I trust the fact that the first element in the lastTransactions is actually the last transaction?
The lastTransaction array will contain an entry for each originalTransaction Id within the subscription group. Ensure that you are looping through the lastTransaction array and finding the subscription information of the product which you are interested in. The signedTransactionInfo will contain the current entitled transaction for a subscription for that originalTransaction Id. The expireDate will be the time on which the current entitled subscription will expire or renew as per autoRenewStatus in signedRenewalInfo.
