This article by AiTrillion talks about how you can export web push subscribers from AiTrillion or import subscribers from another app into AiTrillion.
Web push notifications typically operate on a token-based system. These tokens are a unique set of parameters that allows one to send messages to an identified and accepting device. Because these tokens cannot be transferred or changed in any way, you can neither import web push subscribers into AiTrillion nor export the same.
