Is it possible to send (broadcast) a Firebase Notification from a script to all users without requiring access tokens? From within the Firebase console, no access token is required, so I was wondering if this functionality is available when sending a data notification from a PHP script.
I found this question, but all the answers required to set the to or the registration_ids JSON field. Like so:
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{ "data": { "score": "5x1","time": "15:10"},"to" : "<registration token>"}' https://fcm.googleapis.com/fcm/send
I would prefer not to handle the collection of all access tokens and send a notification to everyone using the app automatically.
