Issue Details

• Electron Version:
  • v11.2.1
• Operating System:
  • macOS 10.15.6
• Last Known Working Electron version:
  • This has not been working for me before

Expected Behavior

When executinginAppPurchase.restoreCompletedTransactions() I expect the app to open a dialog and to ask the user for its app store credentials. I would also expect the inAppPurchase.on('transactions-updated' ...) transaction handler to be triggered so I receive the recipe.

Actual Behavior

Nothing happens after inAppPurchase.restoreCompletedTransactions() is executed.

To Reproduce

Just execute inAppPurchase.restoreCompletedTransactions() in the main process of an electron app (electron version v11.2.1).

Additional Information

The use case for this functionality is not only to restore already purchased products but also to redeem promo codes.

Thanks for reporting this and helping to make Electron better!

Would it be possible for you to make a standalone testcase with only the code necessary to reproduce the issue? For example, Electron Fiddle is a great tool for making small test cases and makes it easy to publish your test case to a gist that Electron maintainers can use.

Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.

I'm adding the blocked/needs-repro label for this reason. After you make a test case, please link to it in a followup comment.

Thanks in advance! Your help is appreciated.

Hi, did you resolve the problem? i have the same issue here, is this api broken? i'm using electron version 28.

Hi @ChrisChou-freeman,

this is a long time ago but as I remember I had a misunderstanding about how the API works.

I think:

1. you have to put a button somewhere that says "restore"
2. When the user clicks the "restore" button, you have to send an IPC message to the main process, the main process then executes inAppPurchase.restoreCompletedTransactions() when it receives the message from the render process.
3. You then can wait for inAppPurchase.on("transactions-updated" () => ...) notifications. Especially for notifications where transaction.transactionState === "restored"

Hi, sorry for take this long to response, didn't notice email before, yes this is how i implement it in my code, my problem is when i call inAppPurchase.restoreCompletedTransactions(), I didn't receive any "transactions-updated" event, it just does nothing. but when i test in testFlight environment call in-app-purchase api it can receive "transactions-updated" event normally.
