Hello,
I’m currently integrating Samsung IAP into my app, and I’m trying to test in-app purchases using a test account.
However, when I try to make a test purchase, I get the error: IAP_NOT_SUPPORTED.
My app is uploaded as a “Beta” in the Seller Portal.
Is there a checklist for enabling IAP in test mode? Do I need special device or account settings?
Thanks!
Hello ^^
Did you download the application on the device from the Beta URL? You need to participate in the Beta from the Galaxy store in order to test the IAP functionality. Make sure to launch the closed beta first and then participate in the closed beta using the provided URL.
Check the documentation for reference: Beta Test - Samsung Galaxy Apps Seller Portal
Also make sure you followed all the steps mentioned in the documentation, including adding the billing permission in your application’s Android Manifest: Integrate the IAP SDK into Your App | Samsung Developer
