Subscription Expiration Date

Question

I have a question regarding the receipt format for In App Purchases.

The main receipt object has a field called Subscription Expiration Date.

But what if an app has multiple types of renewing subscriptions, what will this field reflect then?

Answer 1

It is called Subscription Expiration Date in the documentation, however if you read below the actual name of the json key is expires_date, just wanted to point that out before you go on a search hunt not finding it in your app.

To answer your question, you will see that on the documentation, that specific key Subscription Expiration Date is listed under a heading called In-App Purchase Receipt Fields. That means, and I can confirm from my own experience, that this key is present for every In-App purchase of a subscription individually and every renewal thereon forth. That means there can be multiple purchases, each as their own entry into the receipt-json, with each having a expires_date.

If you want to use that key for validation, the receipt will have a request date sent from the apple server. Use that date to see if one of those subscriptions is still running.

Hope this helps.

Edit: Here's an example of an actual parsed receipt for orientation. Note That I have removed some ids for safety. Here you see a receipt where at the top you see receipt specific information, followed by a one time purchase and then a yearly subscription that was renewed about 4 times.
