The app notification API url looks like the following:
"/v3/apps/{aId}/merchants/{mId}/notifications";
The body of the post message is an AppNotification, which contains a Reference app, which appears to be "The app the notification will be sent to. This will be autopopulated by the server." Thus, it would appear that the one app could send a notification to another app. However, in trying to verify this, my receiver is not receiving the notification.
Can you confirm that one app should be able to send to another app?
Thank you.
