Application Restrictions

To avoid the attacks toward mobile numbers and email addresses, SMN exerts the flow control on critical APIs as follows:

  • API for adding a subscriber: SMN publishes a confirmation message to terminals, such as a mobile number or an email address. Flow control is triggered when the total number of confirmation messages exceeds a specific threshold. SMN stops sending a confirmation message to terminals in the flow control period.
  • API for directly publishing an SMS message: SMN controls the SMS publishing frequency and total SMS numbers of a single mobile number.
