voip push payload

With the introduction of iOS 13 and the modification to the voip pushkit handling, we are attempting to seperate our push message and push voip call notification.


We are looking to upgrade from the legacy push binary system to the new HTTP/2 gateway. However we are having trouble figuring out how to format the json message to trigger the voip call to trigger pushkit.


Does anyone know have an example of how to trigger the voip pushkit call with the HTTP/2 gateway.

We are going to use this project to send pushes from our backend: https://github.com/node-apn/node-apn
I know they are updated to the current push system using HTTP/2, so maybe you can find your answer there.
