iOS In-app purchase nightmare

Question

We are developing an App with Ionic and cordova-plugin-inapppurchase. We've been struggling more than a week as we get the following error when we try to restore a purchase:

RMStore: unknown product id com.company.appname.myID

{"errorMessage":"Unknown product identifier","errorCode":100}

productId = 'com.company.appname.myID';

Answer 1

This post is old, but I was able to fix this problem for myself tonight. Using Ionic v1 with the cordova-plugin-inapppurchase, my solution was to change com.company.appname.myID to just myID (the product id of the in app purchase).

I also had a few other problems causing the same exact error message. The main one was needing to inAppPurchase.getProducts(productIds) before attempting inAppPurchase.buy(productId). Also, make sure you're testing on a real device, with a test account created on iTunes connect, and logged out of any other apple ids on your device (I signed out through the iTunes Store app).

Good luck future readers!
