We are a believer in Transparency, at PushEngage. We wrote an article about how to achieve full vendor portability with Web Push Notifications here. For Push Notification to work, it needs the GCM key.

In order for you to export your subscribers successfully and to use them through another API, you will need to configure PushEngage (or for that matter any provider) with your own Firebase Cloud Messaging Sender Id.  We wrote about this in our FAQ as well. Google/Firebase Cloud Messaging  is a  service that enables developers to send push notification messages between client browser and serve them.

Note: This is a critical setting, so please make sure you make this in an email account that you or your company owns.
