I am looking to build a ios application that will use an auto-renewable subscription on a yearly biases.My question is, how can we be notified when a user cancels a subscription in IOS, so that we can cancel the users features

sorry if I'm duplicating the reply:

if the receipt status is 21006 and there is a key named cancellation_date, then it's a cancellation, you can find the new expiration date in that key but it's a formatted date, if you need a better value to parse check for receipt['latest_expired_receipt_info']['cancellation_date_ms'] same as expires_date

do someone known how to be notified by apple without sending verify requests? it would be reasonable to check only when the product is expiring instead to querying each times for all products because of possible cancellation

First things first. If you're app is not a periodical like a magazine, then you should steer away from ARS (auto-renewable subscriptions). Apple may reject it and insist you use NRS (non-renewing subscriptions).

It's more code than I can practically paste in here, but please follow this guide from Apple on Verifying In-App Purchase Receipts.

Basically you'll be putting the receipt and your secret in a JSON object and sending it to Apple. It's preferable to do this from your server and not from the app. Here is a good guide on Verifying Store Receipts Using PHP and cURL

The JSON object will look something like this:

{
"receipt-data" : "(receipt bytes here)",
"password"     : "(shared secret bytes here)"
}

Apple will respond with another JSON object that has info such as expiration date.

    Each time a subscription renews a new receipt will be generated which will be different from the original receipt. So, no, the receipt data is not constant for a given product ID. Also if you use `restoreCompletedTransactions` to extend a subscription to a user's new device, new receipts will be generated that reference the same subscription time period. It can become a dizzying array of receipts. – Andrew Mar 06 '13 at 10:51
  • Actually at first time i subscribed and i got the receipt-data and that receipt-data is stored in plist after one year the same receipt will sent to the apple server . second year same receipt data will send to the apple server or it will be changed – MANCHIKANTI KRISHNAKISHORE Mar 06 '13 at 11:12
  • i am doing this on auto renewable subscription .If suppose user dont cancel his subscription he will be charged again in this process how he will be charged through our app or directly he will be charged from the user credit card – MANCHIKANTI KRISHNAKISHORE Mar 06 '13 at 11:42
  • He will be charged directly from his credit card automatically by Apple at the end of each subscription period. As for your previous comment, you can simply store the original receipt and just send that to Apple each time for verification. For ARS Apple will always respond with the latest receipt for that product ID. So you don't necessarily have to store the new receipts. – Andrew Mar 06 '13 at 19:31

    Great. If you could select my answer as the correct one I would greatly appreciate it. – Andrew Mar 08 '13 at 05:11
  • Andrew a small doubt in my app there is no user login so how can i store the transaction receipt on my online server.if suppose 10 users subscribe my app all the 10 transaction receipts are stored in my online sql server how can i differentiate that this particular transaction receipt belongs to user . – MANCHIKANTI KRISHNAKISHORE Jul 04 '13 at 07:05

    When saving receipts on your server that you received from the app, you should store a unique ID along with it that identifies that device. I assume you already have a way to differentiate individual devices? The way I do it is, when the user first launches the app I create a unique ID and store it on the device. Whenever there's a request to the server, the Unique ID is sent along with it to identify the device. – Andrew Jul 06 '13 at 19:15

  • has anyone ever gotten erroneous receipts that have the expiration_date be before the purchase_date? I've got this testing in sandbox mode. – MiMo Jul 16 '14 at 22:31
  • @MiMo I haven't seen that but it wouldn't surprised me since the testing mode is a bit clunky. – Andrew Jul 20 '14 at 17:54
