How do we know if messages have been successfully delivered?

SAP Live Link 365 uses standard SMS Delivery Acknowledgments (Acks). Delivery Notifications are message acknowledgments sent from the SAP network to customers. When delivering messages through our network, customers can request to receive the following three levels of acknowledgment:


  • SAP Ack
  • SMS-C Ack
  • Handset Ack.

For unsuccessful delivery attempts, SAP returns a negative acknowledgment (Nack) outlining the reason for the failure. Some Operators might not support mobile / handset acks, which means SMSC ack will be the final acknowledgement.
