Is there any possibility to retrieve/get GCM message_id in service worker push event?
We have built an application to send browser push notification, and for notification data (title, body, image, etc.) we retrieve through our internal API. All seems working as expected, but we need to pass GCM message id to our API and according to GCM message_id we serve relevant notification data to requested service worker event.
Can anyone share your idea's or solution how to pass GCM message_id?
We tried a lot but haven't found any solution.
