Hi Premkumar,

Thank you for reaching out. We do not currently provide a feature to track notifications or secure messages. Our endpoints will attempt to send the notication/message and in the case of a failure, provide more details, however, they do provide additional information that would enable you to determine whether or not a customer opens the message/ notification. I will create a ticket for our team to investigate the possibility of adding this functionality in the future.

Thanks,
Solène
