Problem

When attempting to send a test push notification campaign, the notification fails, and the following message is displayed: Installed User not found for Mobile Number = 0000000000

Solution

  • Use the unique ID field of reachable user instead of the Mobile Number attribute to ensure push notifications are sent.
  • The unique ID field can be found in the user profile with the name ID.
  • The unique ID is unique to each user and is used to determine whether the user can receive push notifications.​​
