Is someone able to please write up a quick few steps on how to get the whole process in a state you can test locally on your iPhone?
This is what I have so far:
create a sandbox account in appstore (appstoreconnect → Sandbox → +)
on your iPhone log out of your normal account and login using the sandbox acc
deploy the app locally using Rider to your iPhone in “Release | iPhone” or “Debug " iPhone” mode and try to make a purchase (this is with a dev certificate and a Wildcard identifier, let’s say the identifier used is com.testing1.game1)
Get an error saying “Invalid Product: …”
Is someone able to add the steps I’m missing?
Also I’m puzzled on how to add a product to a game that is not on the appstore? (the game I’m working on is not ready to for a Test Flight)
Got it working. To support this community and for anyone wondering, the process is this:
[Optional? at testing stage] Agree to Agreements, Tax, and Banking - includes filling out tax forms / bank details Agreements, Tax, and Banking
Create a mock / placeholder / throwaway app in the appstoreconnect (this includes creating a identifier/profile) https://appstoreconnect.apple.com
(Save any changes, you won’t need to Submit for Review, you also don’t need to upload your .ipa)
copy the bundleId
Create an IAP in the app (App → Features → In-App Purchases) you created in appstoreconnect
(click Save, you don’t need to Submit for Review to test this)
copy the productId
Integrate InAppBillingPlugin (examples are provided in their documentation) into your app’s source code
Paste the bundleId and the productId into your source code respectively
Run VS/Rider to build your app to you device
Create a Sandbox Tester Account in the appstoreconnect (appstoreconnect → Sandbox → Testers → + → Fill in details, ensure country is same as app’s country)
Run the app and trigger purchase
(you don’t need to sign out of your Apple ID, a new prompt will pop up asking you to login - use your sandbox account details)
To sign out of your sandbox account on your device go to Settings → App Store → SANDBOX ACCOUNT → Click on Apple ID to Sign Out
