I want send multiple notifications with one HTTP request to Firebase using REST API
Documentation says - "You should combine requests and send" https://firebase.google.com/docs/cloud-messaging/send-message#send-messages-to-multiple-devices
curl command for send is curl *** -H 'Content-Type: multipart/mixed; boundary="subrequest_boundary"' https://fcm.googleapis.com/batch
I found that https://fcm.googleapis.com/batch url is no longer supported https://developers.googleblog.com/2018/03/discontinuing-support-for-json-rpc-and.html
What right url for send multiple notifications to FCM?
