Message Center Reference

Message Center is both a place in your app where you can display persistent rich messages, including HTML, video, etc., and a message type. Similar to email, Message Center represents both the medium (the in-app inbox) and the message type (the messages you send to a message center).


  • Message Center inboxes are limited to 250 messages. Exceeding the limit deletes the oldest messages first.
  • Message Center messages expire after 1 year.

See the tutorials for usage information.
