in-app purchase for auto-renewal subscriptions notifications - ios

I've been reading the various threads on in-app purchases auto-renewal subscriptions, and I think I've pieced together most of the information I need, but there are a few missing pieces. I'm hoping someone can help me.
The situation:
I have various subscription packages the user can subscribe to (e.g., package A for £1 a month, package B for £2 a month, etc.). I store the user's subscription information in my database. When the user logs in, I check which package he's on and if it's expired or not. My website, android and iOS all use the same database, hence this approach seems to make sense.
Subscribing users via in-app purchase seems straight forward enough. I check paymentQueue and once the payment is cleared, I can update my database.
My questions:
1) My understanding is the user can use iTunes to manage their subscription. Say, they go in to iTunes and cancel their subscription, how can I be notified so I can update my database? Do I need a daemon that checks expired subscriptions to see if the user renewed?
2) If the user wants to upgrade their subscription from Package A to Package B, how do I handle the pricing? Say on Jan 1st, they buy Package A, I charge them £1.00 and set the expiry date to Jan. 31st. On Jan. 15th, they want to upgrade to package B via in-app purchase. Ideally, I would charge them £2 for Package B minus £0.50 of credit they have for Package A and set the new expiry date to feb 14th. However, Apple forces me to associate each package with a tier price. How can I handle this? I don't want the user to wait until the end of the month to put them on a higher tier package...if they upgraded mid-month, it means they want the new content package B will deliver to them immediately.
Any help appreciated!
Thanks!

1) Yes you'll have to reverify your receipt check out the Receipt Validation Programming Guide in the documentation. They mention some important keys:
status - 0 if receipt is valid, or an error code
receipt - JSON response of the receipt
latest_receipt (auto-renewable only) - base 64 encoded receipt for the most recent renewal
latest_receipt_info - JSON version of latest_receipt
With this information, when a purchase is made, send the receipt to your backend for validation, the backend will keep the receipt in the DB and verify with status = 0 that it's a valid receipt. From there, every x days you can validate that receipt with a chron job, daemon, etc. and reverify. The response back each time will have latest_receipt_info that you now need to save to your DB so you have an up-to-date receipt for the next check in x days. This way you will always have the latest receipt. There is no instant notification for telling when a user cancels a subscription, but with this you'll know every x days if they have the subscription still.
2) Pricing like this unfortunately can't be handled. It was not intended for a user to "upgrade" with subscriptions - each subscription is access to it's own exclusive content as of this writing. However, if a customer emails in and complains about it, you could ask for their user name and figure out in your DB if this user has indeed upgraded mid-month and reimburse them appropriately. Very old-school and not feasible for a big user base, but hopefully you won't have that many and can keep them happy.

EDITED
For the second question, Apple's auto-renewable subscription system does not technically offer upgradeable plans between different products.
Every subscription is a stand alone product and it's up to the user to turn on/off subscriptions manually using the Subscription Manager in the iTunes Store.
However if package A and package B offer the exact same content only different duration than what ajay_nasa said is correct, you can create an single auto-subscription product with different duration options. If the user is on 1 month subscription and then the user tries to change to 2-months subscription they will get the following error message asking them go to the App Store's subscriptions manager
So basically the ONLY place the user can actually change the subscription's length is in the App Store. Whether Apple decide to pro-rate the amount left on the old subscription or just append it to the current one is really up to Apple. You need to make sure the user have access to the subscription as long as it's active by reading the Original Purchase Date and Subscription Expiration Date field from each receipt entry and determining the start and end dates of the subscription.

Answering question 1, you can verify subscription receipts in the same way as other IAP, but you'll need to check it periodically to see if the subscription has expired (the verification will tell you if it's expired).
There is more info on the Apple docs here:
http://developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/RenewableSubscriptions/RenewableSubscriptions.html

Actually, Apple's auto-renewable subscription system does offer upgradeable plans.
To achieve this we simply should add duration in existing Auto-Renewable Subscription. Every Auto-Renewable Subscription could be family of Subscriptions so whenever developer wants to achieve upgradation in subscription he should add duration in existing Auto-Renewable Subscription with different productID.
Whenever, user upgrade his plan in between the month then his upgrade plan will be automatically works from next month.

Answering to your question #1
Recently Apple launched a feature to enable server notification whenever the subscription is renewed. However, the subscription should be in-app.

We Need to Check Cancellation-Date provided in Receipt.

iOS auto-renewable subscriptions and restoreCompletedTransactions(): is the transaction removed from the queue after expiration or cancellation?

After a long search for an answer, I want to ask a very simple question here. Are transactions associated with a auto-renewable subscription removed after the expiration date from the list of transactions that can be obtained using the restoreCompletedTransactions() method?
In its simplest implementation, is it possible to manage application content associated with a auto-renewable subscription without using Validating Receipts? And using only the result of the restoreCompletedTransactions() method?
You have two questions here.
1) Are transactions associated with a auto-renewable subscription removed after the expiration date from the list of transactions that can be obtained using the restoreCompletedTransactions() method?
Answer:
No. Those entries will always remain there and when you validate the receipt, you will get it back in response. By Doing the Restore purchase won't delete the existing entries from receipt. When you testing the In app purchase with Sandbox account then you will have 35 mins to use that account within 8 Hours. You can do whatever you want. You can do subscription again(In this case system will say us that your subscription is still running). After 35 mins of first purchased, Plan will be considered as Cancel and you need to do Subscription again(Only in Sandbox mode, Well In production mode May be it will not ask to do subscription again? I am not sure here.)
2) Is it possible to manage application content associated with a auto-renewable subscription without using Validating Receipts
Answer: No. Its good to use the receipt validation for locking/unlocking content of your application.

Handle Auto Renew Subscription iOS SDK

I am developing an app which requires auto renew subscription monthly and I want to maintain that on per user basis who logged into my app. is it possible anyhow with in app purchase. Also how can we handle cancelation of subscriptions ?
I want to maintain all this on my own server.
In the StoreKit documentation, it mentioned in Cancellation section:
A subscription is paid for in full when it’s purchased and can be
refunded only by contacting Apple customer service. For example, if
the user accidentally buys the wrong product, customer support can
cancel the subscription and issue a refund. It’s not possible for
customers to change their mind in the middle of a subscription period
and decide they don’t want to pay for the rest of the subscription.
To check whether a purchase has been canceled, look for the
Cancellation Date field in the receipt. If the field has a date in it,
regardless of the subscription’s expiration date, the purchase has
been canceled—treat a canceled receipt the same as if no purchase had
ever been made.
Depending on the type of product, you may be able to check only the
currently active subscription, or you may need to check all past
subscriptions. For example, a magazine app would need to check all
past subscriptions to determine which issues the user had access to.
Bear in mind that users can cancel the subscription anytime without opening your App. Therefore, you have to check the status of subscription every time the user logs into your App.

How do I verify IOS In-App Purchasing Receipts in Bulk?

I'm working on an iOS app that will use Apple's in-app purchasing framework to let the user create auto-renewing subscriptions.
I want my server to check periodically that none of the subscriptions have expired. Apple's Receipt Validation Programming Guide describes a verifyReceipt web service that appears to validate a single receipt.
However, if I want to bulk-verify my entire database every few days, is there a better way to do that than a storm of individual verifyReceipt calls?
You don't need to need to bulk-verify your entire database. A subscription is valid for a fixed duration. If the user cancels their subscription then this takes effect at the next renewal period, not immediately.
Apple customer service can refund a subscription if a user has a case (wrong product purchase is one example they give) but this would be a pretty low figure - and your app should also check for a valid subscription when it starts.
So you should only need to verify subscriptions that are known to be expiring "today".
To my knowledge there's no way to send multiple receipts in one bulk request to validate them in the iTunes servers... You have to send one by one. (Multiple requests)...
I don't know if how you are planing to solve this is the best approach. Apple has extended documentation on how to handle auto renewal subscriptions, most of the times you check the validity of the subscription in the app itself.
Check the in-app purchase documentation. It's a very good read if you plan to depend on in-app subscriptions for your business model:

iOS In-App purchase subscriptions integration with a third party system

I need to build an app for a system, which already has a subscription on its website. It looks like Apple doesn't allow to use any own subscriptions and forces to integrate any app with iOS in-app subscriptions.
Is it any way to integrate two subscription systems? The main problem is that users can manage iOS subscriptions via iTunes and I can't find whether it's possible to get information about this and to stop subscription in the existing system if it's stopped via iTunes.
So is it possible to get notifications about unsubscribed iTunes users?
Using third party subscriptions
First off, it is possible to support an existing subscription system in your app, but it must be in addition to the App Store subscriptions. Also you have to be very careful about the UI you use. You can't prompt users to bypass the App Store and purchase through your server, but you can offer existing subscribers the ability to sign in with credentials they may have previously obtained through your website.
That said, Apple can be fairly capricious in their rulings on what is and isn't allowed in the App Store. I have worked on apps that have done this sort of thing, but they have been for fairly well known magazine publications. There's no guarantee that they will allow it for everyone.
Detecting unsubscribed App Store subscriptions
As for using App Store subscriptions, when a user purchases a subscription in your app, they will receive a receipt in the SKPaymentTransaction object. This receipt should be posted to your backend server to make sure it is valid before you give the user access to anything. See the In-App Purchase Programming Guide for more details.
When you setup a subscription type, you specify how long that subscription lasts. So if you log the transaction date in the SKPaymentTransaction when you receive a receipt, you can determine exactly when that subscription should expire by adding the duration of the subscription to the transaction date.
If it's an auto-renewing subscription, you will receive a new receipt when the subscription is renewed. So once you have validated that with your backend server, you can update your expiry date based on the new transaction date. If you don't receive a new receipt before the first one expires, it's likely the user has cancelled their subscription.
On the backend, your server can also tell when a particular subscription will expire based on the response from the verification server. First there is the status code which will tell you whether the subscription has already expired, but there is also an expiry date returned in the decoded receipt which will tell you when it is expected to expire if it hasn't already.
For more details, see the Auto-Renewable Subscriptions documentation.
Testing auto-renewing subscriptions
It's worth noting that when you are testing auto-renewing subscriptions in the App Store sandbox environment, the length of the various subscription types is dramatically shortened to make it easier to test. For example a 1 week subscription lasts only 3 minutes in the sandbox environment. You can see the full list of times in the iTunes Connect Developer Guide.
So you want the people that have bought the service from the website to be able to use the app, exactly like if they had purchased it from in App Purchases and in App Purchases people to be able to join the service just like people that joined through the site? As far as I know, Apple doesn't allow you to pay through other services as you said, but let's say someone buys the service from the app. What should happen would be that the money will be transferred to the company. Then after the payment you should include some code doing what the site does after a new person has payed for the service, so create his account as a paid account. Then, the app should also have a login screen where the registered users (no matter where they registered from) will be able to login into the app and use the service. Now the problem is indeed that if the subscription is stopped through iTunes you would never know, though a way around this would be to make a check in the server of this company which should monitor the income coming from one account. Then if this user has stopped paying (or stopped the subscription) you would be able to stop the service from the app. And you should recheck the server for payment after the duration of the subscription has passed, let's say a weekly subscription should be checked every week. (Sorry I would do this a comment but I haven't got enough reputation for this)

iOS 6 - How to validate in-app renewable subscriptions?

I am building an app that offers a 30-day subscription to premium services in the app.
I am familiar with in-app purchases (consumables) and have everything setup up for that. However, I haven't found any good tutorial or explanation of what the proper procedure for validating auto-renewable subscriptions.
Can anyone point me in the right direction?
What I would like to do is have the subscription setup like this:
User purchases in-app subscription and is verified
Subscription End-Date (30 days from purchase) is added to network database with user's account info
How to detect when the subscription is renewed so I can update the network database
UPDATE
So I have figured out the original purchasing and receipt verification, so all good on that. Then getting expired date by getting the value of 'expires_date' from the receipt data.
What I need to accomplish now is the best way to check for ALL completed transactions on app load (including any auto-renewed subscriptions) so I can unlock premium services. Using 'restoreCompletedTransactions' allows me to receive old receipt data, but it forces the user to enter a password, and I would like to avoid this. What are the alternatives?
a user purchases a product and you save the receipt. keep track of a timestamp so you know how long the subscription is valid for. on each launch you validate the receipt. you will always get the latest receipt so you know whether the product was renewed. using the timestamp you can make sure the user doesnt get access after their subscription has cancelled.
