In the documentation for FCM https://docs.mendix.com/howto6/setting-up-google-firebase-cloud-messaging-server there still talking about sender id and server id. However the current version requires a private key file. Anybody familiar with setting this up with FCM?
Hi Ramli, received from Mendix support: You should generate a new private key through Project Settings > Service Accounts from the Firebase Console. You can then take the private key from the generated JSON document.
You might want to use the Mendix support for that matter. I myself had the same trouble and decided to contact the support directly to get the right instructions. They are still updating the documentation apparently.
