Getting error message when sending test notification request. Sandbox notification is configured properly. I have tried to delete and add it again, tried with both v1 and v2. Getting same message anyways. When I do same request to production API URL it works fine. I can also get notifications history for sandbox but obviously it is empty: {"notificationHistory"=>[], "hasMore"=>false}
Please confirm the bid field is correct in your JWT header.
bid field is correct. As I mentioned I don't have such error for production environment.
Based on our server logs, I think the bid you're submitting may be incorrect. Bundle IDs are case-sensitive, so be sure the one you submit matches your app's Bundle ID exactly. If you're still experiencing issues, I suggest filing a Feedback Ticket as my colleague suggested, and we can investigate further. Thanks!
