## Discussion

Discussion There’s no user interaction necessary for the framework to send this message. If the message sends successfully, the framework displays a notification indicating sending the message was successful. Upon error, this method throws a MSCriticalMessagingError/errorDomain error. note: The system may impose a rate limit on frequency of messages sent, if usage exceeds this limit the framework  returns a  MSCriticalMessagingError.sendFailed error.
